2 Installation and Dimendion 2 INSTALLATION AND DIMENSION 2.1 Environmental Requirements The design of the cabinet to house the CNC unit, the keyboard panel and the LCD display is the responsibility of the machine tool builder. The cabinet must be constructed and the unit installed in an environment satisfying the following conditions Ambient Temperature When operating: 0 o C to 45 o C. When storing or transporting the system: -20 o C to 55 o C. Temperature Variation Maximum: 1.1 o C/minute. Humidity Normally: 80% RH or less (Relative Humidity). For short period: maximum 95% RH. Vibration When operating: <= 0.075 mm with frequency 5 HZ. Noise When operating: withstand 2000V/100 sec pulse width every 10 m sec. Contact us when installing the system in an environment with high degree of dust, coolant, or organic solution. 2.2 Cabinet Considerations Pay attention to the following items when designing a cabinet for HUST H6C controller. The cabinet must be constructed to house the CNC unit, MDI panel and is always a completely enclosed box. The max temperature rise within the cabinet during operation should NOT exceed 10 o C higher than the ambient temperature. Sealing of the cable inlet/outlet or doors must be done thoroughly. To avoid the noise interference, various units, the connecting cable and the AC power source must be mounted at least 100 mm apart. In a magnetic field environment, this distance should be increased to at least 500 mm. When mounting the servo amplifier, please refer to the Servo Motor Manual.
HUST H9C Connecting Manual 2.3 Thermal Design for the Cabinet The cabinet for the control unit must be a closed structure, and the temperature rise within the cabinet must be 10 o C or less than the ambient temperature. When designing a metal cabinet for a CNC unit, two factors must be considered, which are the heat source and the radiation area. The heat source is from the CNC unit itself, users cannot do anything to reduce it. Therefore, the one thing that the user can do in controlling the temperature rise is the radiation area. The allowable temperature rise inside a metal cabinet can be estimated as follows: 1. With a cooling fan, the allowable temperature rise is 1 o C/6 W/1 m 2. 2. Without a cooling fan, the allowable temperature rise is 1 o C/4 W/1 m 2. This means that a cabinet with a radiation area of 1 m 2 and a cooling fan will have an internal temperature rise of 1 o C when a heating unit of 6 W (4W without a cooling) is inside the cabinet. The radiation area of a cabinet is the entire surface area of the cabinet minus the area contacting the floor. Example 1 (with a cooling fan): A cabinet has a 2 m 2 radiation area with a temperature rise of 10 o C. The maximum allowable heat value inside the cabinet is 6 W x 2 x 10 = 120 W. Therefore, the heat generated inside the cabinet must be kept less than 120 W. If the heat generated is 120 W or more in the cabinet, some other cooling devices, such as cooling fins, must be incorporated in the unit. Example 2 (without a cooling fan): A cabinet has a 2 m 2 radiation area with a temperature rise of 10 o C. The maximum allowable heat value inside the cabinet is 4 W x 2 x 10 = 80 W. Therefore, the heat generated inside the cabinet must be kept less than 80 W. If the heat generated is 80 W or more in the cabinet, some other cooling devices, such as fan, or cooling fins, must be incorporated in the unit.

HUST H9C Connection Manual 4.3 Emergency-Stop Circuit The electronic circuit in the controller requires about 100 milli-seconds to reach stable state when power is turned on. During this unstable period, the servo motor should not be turned on. To accomplish this purpose, HUST internal PLC has a "Servo-on Timer" with 1.5 seconds. When the timer is up, the controller sends an O-bit high (1) to turn on the servo driver. Fig 4-16 is an emergency stop circuit. When the hardware OT limit switch is touched or the E-stop button pushed, the controller will be in a state of emergency stop and the servo-on switch on the servo motor will trip off. For safety reason, the E-stop button, the hardware OT limit switch, and the E-stop relay should be connected in-series and the servo-release button in-parallel with the hardware OT limit switch. Please note that the E-stop button and the hardware OT limit switch are of normal-closed type. During normal operating condition, the servo-release button is at OFF position. After emergency stop has occurred and all power to servo motor has been cut off, servorelease button can be pushed in to supply power to servo motor to bring the machine tool to normal operating range. Limit Switch Fig 4-16 Emergency Stop Circuit
4 Input/Output Interface Connection Notes: 1. Relays A and B are protection circuit during power-on. The purpose is to prevent the tool from being damaged in case of power-on failure that results in a total output. 2. Relay C is a servo-on relay. 3. Relay A and B are outputs in PLC. 4. Generally, Relay C has multiple connecting points for multiple servo. Each servo motor requires independent connecting point. Do NOT connect servo motors in parallel because some servo motors cannot be connected in parallel. See Fig 4-17. 5. The arrangement of servo-on in PLC. See Fig 4-17.

Rotating Signal for Spindle Motor (S085) S085=1 signal will be sent to PLC when spindle motor is rotating (in motiom). Signals for Servo Motor Running Status (S088) When one or more of the four axis motors (X/Y/Z/A/B/C-axis) are moving (in motion), the CNC will send the signal S088=1 to PLC.
5 Interface Between CNC & PLC Key Signals from PC or Easyview (S0104~S111) When the special key that was designed on PC or Easyview is pressed, a signal is sent through RS232 to the controller which will send the status bits S104~S111 (=1) to PLC. Battery Down Signal(S120) If the battery BT1 is down, the controller displays ERROR 30 BATT. Low and sends S120=1 signal tp PLC RS232 Linkage Signal (S123) When CNC controller established linkage with PC through RS232, the CNC will send S123=1 signal to PLC. Hardware Interrupt Signal(S125) Key Strobe for Key Being Pressed Down and Hold Down (S126) When a key is pressed down and hold down, the controller will send S126 = 1 to PLC. When key is released, S126 = 0. Ladder Simulation Mode (S127) S127 =1 will be sent to PLC when a ladder program edited in PC is being simulated from the CNC controller. X/Y/Z/A/B/CU/V/W - axes Home Signal at Machine Coordinate = 0 (S160~S168) When the tool is at X-axis home location (machine coordinate X=0), S160 = 1. When the tool is at Y-axis home location (machine coordinate Y=0), S161 = 1. When the tool is at Z-axis home location (machine coordinate Z=0), S162 = 1. When the tool is at A-axis home location (machine coordinate A=0), S163 = 1. When the tool is at B-axis home location (machine coordinate B=0), S164 = 1. When the tool is at C-axis home location (machine coordinate C=0), S165 = 1. When the tool is at U-axis home location (machine coordinate A=0), S166 = 1. When the tool is at V-axis home location (machine coordinate B=0), S167 = 1. When the tool is at W-axis home location (machine coordinate C=0), S168 = 1. Positioning Execution in PLC (S208-S216) When execute the X-axis move by PLC, S208=1. S208=0 when motion completed. Please consult the illustration of C208 When execute the Y-axis move by PLC, S209=1. - 7
HUST H9C Connecting Manual S209=0 when motion completed. Please consult the illustration of C209 When execute the Z-axis move by PLC, S210=1. S210=0 when motion completed. Please consult the illustration of C210 When execute the A-axis move by PLC, S211=1. S211=0 when motion completed. Please consult the illustration of C211 When execute the B-axis move by PLC, S212=1. S212=0 when motion completed. Please consult the illustration of C212 When execute the C-axis move by PLC, S213=1. S213=0 when motion completed. Please consult the illustration of C213 When execute the U-axis move by PLC, S214=1. S214=0 when motion completed. Please consult the illustration of C214 When execute the V-axis move by PLC, S215=1. S215=0 when motion completed. Please consult the illustration of C215 When execute the W-axis move by PLC, S216=1. S216=0 when motion completed. Please consult the illustration of C216 PS1. R180R188R160R168 setting range:+32767-32767. 2. When C223=0, the value is the position of absolute coordinate in R180R188. Default#11800=10 #11800 setting range1~1000. 3. When C223=1, the value is the position of incremental coordinate in R180R188. Default#11800=1 #11800 setting range1.
