1 RoHS-Compliant for Standard AC Motors SBW The SBW provides instantaneous stop, forward/ reverse operation, electromagnetic brake control and thermal protector open detection functions integrated into one unit. These brake packs can sense when the thermal protector is opened, further ensuring the safety of your equipment. Features Four Functions in One Integrated Unit The SBW provides instantaneous stop, forward/reverse operation, electromagnetic brake control and thermal protector open detection functions. Thermal protector open detection function (Available only when combined with a motor having a built-in thermal protector) When the motor's thermal protector (overheat protection device) is activated, the SBW outputs an alarm signal and automatically cuts the power supply to the motor. The motor will not restart by itself, even after the temperature drops and the thermal protector recovers, until the power is cycled. Possible to reset the alarm through external signals. Wide Voltage Range of 1 to 23 VAC The SBW covers a single-phase voltage range of 1 to 23 VAC 1%, /, accommodating all of the world's key voltage specifications. Conforms to Safety Standards This is the world first brake pack which conforms to safety standards. The CE marking is used in accordance with the EMC directives and low voltage directives. Supports Motors with 1 to W (1/ to 1/ HP) Output The SBW can be used with induction, reversible, electromagnetic brake and watertight, dust-resistant motors with an output range of 1 to W (1/ to 1/ HP). Switchable Sink/Source Logic Select the sink mode or source mode for the input/output circuit. You can change the setting at any time. Safety Standards and CE Marking Standards Certification Body Standards File No. CE Marking UL UL E121 CSA C22.2 No.1 Low Voltage Directives EN 1 EMC Directives Conform to EN Standards EN -1 The EMC value changes according to the wiring and layout. Therefore, the final EMC level must be checked with the brake pack incorporated in the user's equipment.

6 I/O Signal Circuit The I/O signal circuit can be switched between the sink mode and source mode using the sink/source select switch on the brake pack. The factory setting is the sink mode.

The motor does not operate if they are input ahead of AC power. The ALARM indicator will light and ALARM output will switch to "OFF." 2 The brake release input becomes ALARM-RESET input when the ALARM output is OFF. 3 Only for electromagnetic brake motors. The induction motor will not accommodate instantaneous forward/reverse switching. Turning the CW operation signal to "" causes the motor's output shaft to turn in the CW direction. Turning it to "OFF" triggers an instantaneous stop. Turning the CCW operation signal to "" causes the motor's output shaft to turn in the CCW direction. Turning it to "OFF" triggers an instantaneous stop. If both the CW and CCW operation signals are simultaneously turned to "," the CW operation signal will take priority. Therefore, the wiring must be changed with an induction motor having four lead wires. [ALARM-RESET Input] Functions as a brake release input during normal operation, and as an ALARM-RESET input when the ALARM output is OFF. When normal: [] Turning the brake release signal to "" disables both the electronic brake and electromagnetic brake. When the CW and CCW operation signals are turned to "OFF," the motor operates via inertial force before coming to a natural stop. When the motor is stationary, the electromagnetic brake is not activated, so the motor's output shaft can be moved freely. Turning the brake release signal to "OFF" (or leaving the signal unconnected) and turning both CW and CCW operation signals to "OFF" will activate the electronic brake and electromagnetic brake, bringing the motor to an instantaneous stop. Once the motor stops, the electronic brake will release automatically. However, the electromagnetic brake will continue to operate and hold the load. When ALARM output is OFF: [ALARM-RESET Input] When ALARM output is turned OFF, turn all input signals "OFF" and input. seconds or more for ALARM-RESET input. Wait at least. seconds after turning the ALARM-RESET input OFF before restarting operation. ALARM-RESET Input or OFF ALARM Activation ALARM-RESET Input. s min.. s min.

7 (Thermal Protector Open Detection) Since the SBW ALARM output function detects the operations of the thermal protector, the current flowing in the motor is monitored. Operation occurs under the following conditions: When the thermal protector built-in to the motor is opened When there is improper connection/disconnection of the power supply cable and motor cable When the input signal is turned "" before the AC power is turned on When the AC power is turned off while the motor is in operation or while it is stopped In the above conditions, state of the SBW ALARM output is "OFF," the ALARM indicator lamp (red) on the panel lights up, and power supply to the motor is stopped. With electromagnetic brake motors, the brake is activated in order to hold the load in position. When the DC power is turned on, the alarm indication lamp lights up instantaneously, but this is not an abnormality. External Controller Limiting Resistor 2. k or more Photocoupler Use a power source of 2. VDC or less, and limit the output current to 1 ma or less. Operating/Braking Repetition Cycle The repeated operation and braking of a motor will cause about a temperature increase in the motor and brake pack, thereby limiting the continuous operating time. Observe the repetition cycle given in the table below for the operation and braking of the motor. The motor may generate heat depending on the conditions in which it is driven. Ensure that the temperature of the motor case does not exceed C. Motor Output Power Repetition Cycle 12 W (1/1/3 HP) 2 seconds or more W (1/11/ HP) seconds or more (A repetition cycle of two seconds represents operation for one second and stopping for one second.) 11
