(Note): NEVER connect the PTC to the power supply.
The servo drive is directly connected to an industrial power supply, with no isolation such as transformer. In
this case, a fuse or circuit breaker must be connected on the input power supply to prevent cross electric
accidents in the servo system. The servo drive is not configured with the built-in protective grounding
circuit. Thus, connect a RCD against both overload and short-circuit or a specialized RCD combined with
protective grounding.
It is forbidden to run or stop the motor by using the electromagnetic contactor. As a high-inductance device,
the motor generates instantaneous high voltage, which may damage the contactor.
Note
1.
CN3 and CN4 are identical communication ports with the same pin definition, and either can
be used.
2. Do not start and stop the servo drive frequently by switching the contactor on and off (less
than twice per 10 minutes) nor use it to directly start the servo drive.
2.2 Wiring in Different Modes
The following are the notices for the wiring diagrams in three different modes:
●
Use the shielded twisted-pair as the AI/AO circuit cables, with both ends of the shield tied to PE.
●
In24V power supply, voltage range: 20–28 V, maximum output current: 200 mA
●
DI8 and DI9 are high-speed DIs. Use them according to their functions allocated.
●
Use the shielded twisted-pair as the cables of the high-speed/low-speed pulse terminals, with both
ends of the shield tied to PE. Connect GND and signal ground of the host controller reliably.
●
Use the shielded twisted-pair as the encoder frequency-division cables, with both ends of the shield
tied to PE. Connect GND and signal ground of the host controller reliably.
●
Customers need to prepare the power supply for DOs, with voltage range 5–24 V. The DO terminals
support 30 VDC voltage and 50 mA current to the maximum.
●
The in5 V power supply supports a maximum of 200 mA current.
