45 4. EtherCAT Communication 4. EtherCAT Communication EtherCAT stands for Ethernet for Control Automation Technology. It is a communication method for masters and slaves which uses Real-Time Ethernet, developed by the German company BECKHOff and managed by the EtherCAT Technology Group (ETG). The basic concept of the EtherCAT communication is that, when a Frame sent from a master passes through a slave, the slave inputs the received data to the Frame as soon as it receives the data. EtherCAT uses a standard Ethernet frame compliant with IEEE82.3. Since it is based on a 1BASE-TX Ethernet, cable lengths of up to 1 meters are possible and the maximum number of connected slaves is 65,535, so it is possible to configure a nearly unlimited network size. In addition to this, when using a separate Ethernet switch, you can interconnect it to common TCP/IP. 4.1 The Structure of CANopen over EtherCAT Servo Application EtherCAT State Machine SDO Object Dictionary Application Layer Registers Mailbox Process FMMU FMMU1 Link Layer Sync Manager Sync Manager1 Sync Manager2 Sync Manager3 EtherCAT Physical Layer The L7N drive uses a CiA 42 drive profile. The Object Dictionary in the application layer includes application data and mapping information from the process data interface and application data. The Process Object () consists of an Object Dictionary that can be mapped to the, and the content of the process data is defined by mapping.

49 4. EtherCAT Communication 4.5 The EtherCAT uses the Process Object () to perform real-time data transfers. There are two types of s: Rx receives data transferred from the upper level controller, and Tx sends the state from the drive to the upper level controller. The L7N uses x16 to x163 for Rx mapping and x1a to x1a3 for Tx mapping. You can map up to 1 objects on each. The following figure shows an example of mapping. x64 - Controlword UINT x67a - Target Position DINT Rx (x16) INDEX (2byte) SUB INDEX (1byte) DATA TYPE (1byte) x64 x UINT x67a x DINT x x x641 - Statusword UINT x664 - Position Actual Value DINT x66c - Velocity Actual Value DINT Tx (x1a) INDEX (2byte) SUB INDEX (1byte) DATA TYPE (1byte) x641 x UINT x664 x DINT x66c x DINT 1 x x 4-5

51 4. EtherCAT Communication 4.6 Synchronization Using the DC (Distributed Clock) The Distributed Clock (DC) synchronizes EtherCAT communication. The master and slave share a reference clock (system time) for synchronization, and the slave synchronizes its applications with the Sync event generated by the reference clock. The following synchronization modes exist in the L7N. You can change the mode with the sync control register. Free-run mode In free-run mode, the L7N operates each cycle independent of the communication cycle and master cycle. DC Synchronous Mode In DC Synchronous mode, the Sync event from the EtherCAT master synchronizes the drive.

88 6. L7 Drive Setup 6.2 Configuring Control Parameters The control parameter setting sequence is as follows: Load the inertia ratio [x21] setting. Adjust the proportional gain with [x211] and [x212]. Increase the gain so that the servo motor does not overshoot or lose control (do not use during speed operations or torque operations). Adjust the speed proportional gain with [x216] and [x217]. Increase the gain so that the servo motor does not vibrate. Adjust the speed integral time constant with [x218] and [x219]. Refer to the following table and set it according to the speed proportional gain The Inertia Ratio [x21] This sets the inertia ratio by calculating the load inertia from the machine system and rotor inertia listed on the motor specification table. The inertia/load ratio is an important control parameter for the operation of the servo. It is crucial to set the correct inertia ratio for optimal servo operation. The following table outlines the recommended control gain for different inertia ratios: Motor Flange 4 ~ 8 Categor y Low inertia Medium inertia High inertia Inertia ratio Inertia (Multiple) Position Proportional Gain Gain Speed Proportional Gain Speed Integral Gain 1 ~ 5 4 ~ 9 4 ~ 1 1 ~ 4 5 ~ 2 2 ~ 7 2 ~ 5 2 ~ 6 2 ~ 5 1 ~ 4 1 ~ 3 5 ~ 1 * You can tune the inertia ratio during a test drive if it is too hard to calculate the inertia ratio before operation. 6-4

It uses them as internal position commands after initial filtering. Current position: Counts the pulse signals received from the encoder and uses the electronic gear ratio settings to convert them to the current position. Position proportional gain [x211] and [x212]: Converts the difference between the position command and the current position into a speed command by multiplying it by the position proportional gain. Recommended = speed proportional gain [x216] / 1 Feed-forward gain [x214]: Uses the differences in to the position command to calculate the gradient. Adds the speed command to the gradient to reduce the time needed to reach the target position. If the which results is too large, then the position controller may overshoot or become unstable. It is important to gradually increase the from a small while monitoring the test drive. Feed-forward filter [x215]: The feed-forward control filter vibrates if the position command changes too drastically. If this occurs, configure the filter until the vibrations disappear. 6-5

L7 Drive Setup The Speed Control Gain Speed integral time constant [x218] Speed command Speed command filter time constant [x21a] + Speed error Speed proportional gain + - [x216] + Torque command Current speed Speed feedback filter time constant [x21b] Speed calculation Encoder signal Current torque Speed command: Operates the speed command through the speed command filter [x21a]. Current speed: Calculates the speed by counting the number of encoder signals as time progresses. Filters the speed to calculate the current speed. The algorithm uses the current torque and inertia to project the speed and compensate for errors which occur when calculating the speed at very low speeds. Therefore, an accurate motor constant and inertia ratio are closely related to the stability of the motor speed control. Speed integral time constant [x218]: Calculates the integral of the speed error. The speed error is the difference between the command speed and the current speed. The speed integral time constant converts the speed error into a torque command by multiplying it by the integral time constant. A decreased integral time constant solves transient response issues and improves speed tracking. If the integral time constant is too small, however, an overshoot occurs. On the other hand, if the integral time constant is too large, an excessive response drop occurs and proportional control takes over. Recommended = 1/speed proportional gain [x216] Speed Command speed Low High Tracking speed Time 6-6

91 6. L7 Drive Setup Speed proportional gain [x216]: Converts the speed error into a torque command by multiplying it by the proportional gain. If the resulting is large, then the speed response accelerates and speed tracking increases. However, vibrations occur if the is too large. If the is too small, then speed response slows down and speed tracking decreases. This may cause the servo to lose power. Speed Command speed High Low Time Speed feedback filter time constant [x21b]: Filters the speed feedback to control vibrations when the speed of the motor changes due to drive system vibrations or vibrations due to gain and too much load inertia. If the is too high, it reduces speed responsiveness and control power may be compromised. Recommended = to speed integral time constant [x218]/ The Torque Command Filter Time Constant Time [x21c] Use a digital filter for the analog torque command voltage to improve the stability of command signals. If the filter is set too high, responsiveness to torque commands will be reduced.

199 1. Maintenance and Inspection 1. Maintenance and Inspection 1.1 Maintenance and Inspection This chapter explains how to perform basic maintenance and inspection tasks as well as diagnose and troubleshoot the servo motor and drive Precautions 1. Measuring the motor voltage: The PWM controls the voltage output from the servo amp to the motor. Because of this, the waves take the form of pulses. Use a rectifier voltmeter for accurate measurements because different meters may produce different results. 2. Measuring the motor current: Use a moving iron ammeter and wait for the motor's reactance to smooth the pulse waveform into sine waves. 3. Measuring the electric power: Use an electrodynamometer based on the 3 power meter method. 4. Other gauges: When using an oscilloscope or digital voltmeter, do not allow them to touch the ground. Use a 1 ma or less input current gauge What to Inspect Wait at least 1 minutes after turning off the power before beginning the inspection because the condenser can hold enough voltage to cause an electrical accident. (1) Inspecting the Servo Motor Caution Wait at least 1 minutes after turning off the power before beginning the inspection because the condenser can hold enough voltage to cause an electrical accident. Inspection Item Inspection Period Inspection and Handling Notes Vibration and sound check Monthly Touch the motor and listen for sounds. The feel and sounds should be the same as usual. Inspect the exterior of the motor Depends on the amount of contamination or damage. Clean the motor with a cloth or air pressure. - Measure the insulation resistance At least once a year Disconnect the motor from the drive and measure the insulation resistance. A normal resistance level is 1 MΩ or higher. Note 1) Contact our service center if the resistance is lower than 1 MΩ. Replace the oil seal At least once every 5, hours Remove the oil seal from the motor and replace it. This only applies to motors with an oil seal. 1-1

200 1. Maintenance and Inspection Inspection Item Inspection Period Inspection and Handling Notes General inspection At least once every 2, hours or after 5 years. Contact our service center. Do not disassemble the servo motor yourself. Note 1) Measure the resistance between the FG and one of the U, V, and W power lines on the servo motor. (2) Inspecting the Servo Drive Inspection Item Inspection Period Inspection process What to do if you find an abnormality Clean the main body and control board At least once a year Check if there is any dust or oil on the components. Clean it with air pressure or a cloth. Check for loose screws At least once a year Check whether the screws are loose on the terminals and connectors. Tighten the screws. Check for defective parts on the main body or the control board At least once a year Check for discoloration, damage, or disconnection caused by heat. Contact our company. 1-2

201 1. Maintenance and Inspection Replacing Parts Mechanical friction and aging may deteriorate the following parts or even cause them to malfunction. This makes it important to conduct regular maintenance checks and replace worn parts. 1. The smoothing condenser: Ripple currents and other factors can cause this part to wear. The lifespan of this part depends on the operating temperature and environment. It normally lasts for 1 years if used continuously in a normal air-conditioned environment. Inspect the condenser at least once each year because it can rapidly age over a short period of time once it starts to deteriorate (inspect it more frequently as it approaches obsolescence). Visual inspection criteria: a. The condition of the case: Check for deformations on the sides and bottom. b. The condition of the lid: Check for notable expansion, severe cracks, or broken parts. c. The relief valve: Check for notable valve expansion and operation. d. Also regularly check whether the exterior is cracked, discolored, or leaking and whether there are any broken parts. The condenser is obsolete when its capacity degrades to less than 85% of the rated capacity. 2. The relays: Check for bad connections and wear and tear on the contacts caused by switching currents. A relay is obsolete when its accumulated number of switches reaches 1,, depending on the power capacity. 3. Motor bearings: Replace the bearings after 2, to 3, hours of operation at the rated speed under the rated load. Replace the bearings if abnormal sounds or vibrations are detected during inspection, depending on the operating conditions. The Standard Part Replacement Cycle Part Standard Replacement Cycle Method Smoothing condenser 7-8 years Replace (determine after inspection). Relays - Determine after inspection Fuses 1 years Replace Aluminum electrolytic condensers on printed boards 5 years Cooling fans 4-5 years Replace Replace with new boards (determined after inspection) Motor bearings - Determine after inspection Motor oil seal 5, hours Replace 1-3
