High voltage remains inside the unit after power is disconnected. Cut off the power supply and wait at least 5 minutes before performing wiring, inspection or maintenance work. Always connect the PE terminal to protective earth to prevent electric shock. Do not operate the drive beyond its rated torque and duty cycle to avoid overload damage. Unauthorized modification of the device is prohibited, which will void the warranty and may cause fire or personal injury. Install an external emergency stop circuit to cut off power immediately when abnormal conditions occur.

CACR stands for AC Servo Drive. SR represents speed and position control type SERVOPACK. The digit 02 means the rated power is 200W. Letter A indicates compatibility with R-series servo motors. Letter C refers to the product design revision. Digit 2 denotes 200VAC power supply and pulse command input for position control. Letter E means the unit matches a 1500 ppr incremental encoder. Letter R stands for rack mounting structure.

The drive supports single-phase 200V to 230V AC input with a frequency range of 50Hz to 60Hz. The three-phase output ranges from 0V to 230V AC, and the rated output current is 1.5A. It supports two control modes including pulse position control and analog speed control with ±10V signal. The matched encoder is a 1500 ppr incremental type. Built-in protection functions cover overcurrent, overvoltage, undervoltage, overheat and encoder fault protection. The operating ambient temperature is from 0°C to 45°C, and the storage temperature ranges from -20°C to 60°C. The relative ambient 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 speed loop integral time is 20 milliseconds. The encoder resolution is 1500 ppr by default. One input pulse corresponds to one encoder count under position control mode. The full range of ±10V analog input corresponds to the motor rated speed under speed control mode.

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

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 firmly connected to protective earth. The RB terminal is reserved for connecting an external regenerative resistor according to actual operating requirements.

Connector 2CN is for control input and output signals. SG is the signal ground terminal. PULS is the pulse command terminal and SIGN is the direction signal terminal for position control. VREF receives the ±10V analog speed command signal. FWD and REV are optocoupler driven terminals for forward and reverse operation. E-STOP serves as the emergency stop terminal. ALM is the alarm signal output terminal with relay contacts.

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

The unit is equipped with a 7-segment LED display. The digit 0 will show on the display when power is connected normally. The real-time motor speed or position pulse value will be displayed during regular operation. The corresponding fault code will appear once a malfunction occurs.

Complete all wiring for power, motor and encoder and check all connections carefully before use. You can use factory default parameters or adjust settings as required. Apply pulse and direction signals for position control, or input analog voltage signal for speed control. Switch running direction via forward or reverse signals. Observe the LED display continuously to monitor operating status and fault information.

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

Code 2 refers to an overvoltage fault, which is mainly triggered by excessive regenerative energy or input voltage surge. Connect an external regenerative resistor and check the stability of the power supply.

Code 3 stands for an undervoltage fault, resulting from insufficient input voltage or loose terminals. Inspect the power supply and retighten all wiring terminals.

Code A represents an encoder fault. Check for broken cables or loose connectors on the encoder line, then reconnect cables or replace the faulty encoder.

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

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

Check the LED status, abnormal noise and surface 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 cooling fan can work stably for around 3 years. Replace aging components in time to guarantee reliable operation.
