Name Description
two
places
Ground terminal
Used to connect grounding wire of power supply and
servo motor.
CN1
I/O connector
Used to connect external controllers. Please refer to
section 3.3 for details.
CN2
Encoder
connector
Used to connect encoder of servo motor. Please refer to
section 3.4 for details.
CN3
Communication
connector
Used to connect RS485 or RS-232. Please refer to
section 3.5 for details.
CN4

CN5
Analog voltage
output terminal
Used to monitor the operation status. The drive provides
two channels, MON1 and MON2 to output the analog
voltage data. Output voltage is reference to the power
ground (GND).
Pay special attention to the followings when wiring:
1. When the power is cutoff, do not touch R, S, T and U, V, W since the
capacitance inside the servo drive still contains huge amount of electric charge.
Wait until the charging light is off.
2. Separate R, S, T and U, V, W from the other wires. The interval should be at
least 30 cm (11.8 inches).
3. If the wire of encoder CN2 connecter is not long enough, please use shielded
twisted-pair cable which cannot exceed 20 meters (65.62 inches). If it exceeds
20 meters, please choose the bigger wire diameter of signal cable to ensure it
will not cause signal fading.
4. When selecting the wire rod, please refer to Section 3.1.6.
