Remark
：
1)
The servo drive is connected to the industry power supply directly, and there is no power isolation like transformer. To prevent electric
shock of servo system, please put a fuse or molded case circuit breaker in the input power supply.
2)
Do not install electromagnetic contactor between the drive and the motor, which can damage the drive.
3)
Please note the power supply capacity when connect to external control power supply or 24V power supply, especially when the power
supply is connected to several drives or brakes. If power supply capacity is not enough, the output current will also be not enough,
which can lead to the damage of drive or brake. Please note that the brake power supply is 24V DC, whose capacity should be
consistent brake power. Please refer to describe of servo motor for related brake power.
4)
Check the servo motor output U, V, W terminal wiring phase. The motor will not run or run out of control and then alarm, or even
damaged by incorrect wiring.
5)
When using external resistor, P+ and D terminal should be open, and the external brake resistor should be connected to P+, C terminal.
When using internal brake resistor, P+ and D terminal should be shorted and P+ and C terminal should be open.
6)
In 1-phase 220V wiring, the main power supply terminal is L1, L2 terminal, and L3 should be empty.
7)
CN2 and CN3 are same defined communication terminals, so that you can use any one of them.
