High voltage remains inside the drive after power off. Disconnect the power supply and wait for no less than 5 minutes before performing wiring, inspection or maintenance work. Always connect the PE terminal to protective earth to avoid electric shock hazards. Do not operate the drive beyond its rated torque and working cycle to prevent overload damage. Any unauthorized modification to the equipment is forbidden, which will void the warranty and may lead to fire or personal injury. Install an external emergency stop circuit to cut off power rapidly in case of abnormal conditions.

CACR stands for AC Servo Drive. SR represents speed and position control type SERVOPACK. The number 02 means the rated power is 200W. Letter A indicates compatibility with R-series servo motors. Letter C refers to the product design revision. Number 1 means 200VAC power supply and analog ±10V speed command input. Letter E stands for 1500 ppr incremental encoder matching. Letter R means rack mounting structure. Y27 is a special customized version, and its basic functions, wiring and parameters are consistent with the standard model of the same series.

The rated input is single-phase 200V to 230V AC, with a frequency range of 50Hz to 60Hz. The three-phase output is 0V to 230V AC and the rated output current is 1.5A. The main control mode is analog speed control with ±10V command signal. The matched encoder is 1500 ppr incremental type. Built-in protection functions include overcurrent protection, overvoltage protection, undervoltage protection, overheat protection and encoder fault protection. The allowable operating ambient temperature ranges from 0 degrees Celsius to 45 degrees Celsius, and the storage temperature ranges from minus 20 degrees Celsius to 60 degrees Celsius. The ambient relative humidity shall not exceed 90 percent and condensation is not allowed.

The default position loop gain is set to 40. The default speed loop gain is 200. The integral time of speed loop is 20 milliseconds. The encoder resolution is set to 1500 ppr by default. The analog input signal of ±10V corresponds to the full rated speed of the motor.

Mount the drive vertically with the heat sink facing downward. Reserve a clearance of no less than 100 millimeters at the top and bottom of the unit, and no less than 50 millimeters on both sides. Ensure smooth air circulation around the drive. Keep the equipment away from direct sunlight, dust and oil mist during installation and use.

Terminals R and S are used for AC power input. Terminals U, V and W connect to the three-phase servo motor. The PE terminal must be connected to protective earth reliably. The RB terminal is reserved for external regenerative resistor connection, which can be wired according to actual working conditions.

Connector 2CN is for control input and output signals. SG is the signal ground terminal. VREF receives the analog speed command signal of ±10V. FWD and REV are forward and reverse operation signal terminals driven by optocoupler. E-STOP is the emergency stop signal terminal. ALM is the alarm signal output terminal with relay contact.

Connector 5CN is dedicated to encoder connection. Terminals A, /A, B and /B transmit encoder phase signals. +5V and GND provide working power for the encoder.

The device is equipped with a 7-segment LED display. When the power is normally turned on, the display shows digit 0. During normal operation, the display will show the current motor speed. Once a fault occurs, the corresponding fault code will be displayed.

Follow the steps below for basic operation. Complete all power, motor and encoder wiring first and check for connection errors. Use factory default parameters or set parameters as required. Input analog speed command signal to start the motor, and use forward or reverse signals to switch operation direction. Observe the LED display in real time to monitor operating status or fault information.

Code 1 indicates overcurrent fault. This problem is usually caused by circuit short circuit, motor overload or wrong wiring. Check the wiring of U, V and W terminals and reduce the load properly.

Code 2 stands for overvoltage fault. It is mainly caused by excessive regenerative energy or input voltage surge. Connect an external regenerative resistor and check the stability of input power supply.

Code 3 means undervoltage fault, which results from insufficient input voltage or loose terminal connections. Check the power supply and fasten all wiring terminals.

Code A represents encoder fault. Check whether the encoder cable is broken or the connector is loose, reconnect the cable or replace the faulty encoder.

Code F is overheat fault. Poor ventilation, damaged cooling fan or long-term overload will trigger this alarm. Clean the heat sink, inspect the fan and reduce the operating load.

Code B and Code C are system internal faults of the drive. When these codes appear, the control board may be damaged and the whole drive needs to be replaced.

Check the LED display and listen for abnormal noise or abnormal temperature of the drive every day. Clean the heat sink and cooling fan, and check the tightness of all wiring terminals every month. Inspect the working condition of the cooling fan and test the performance of internal electrolytic capacitors every year. The service life of internal electrolytic capacitors is about 5 years, and the service life of cooling fan is about 3 years. Replace aging parts in time to ensure stable operation.
