Pin Name
Details
+VDC
Power supply positive connection.
iCS-17xx:20-36VDC
iCS-23xx and iCS-24xx: 20-50 VDC
GND
Power supply ground connection.
Notes:
It is recommended that power voltage of all integrated motors are 24VDC, otherwise if the motor is too hot, it is easy to
transfer heat to the drive, thus damaging the drive.
3.2 Connector P2 – Tuning Port
The P2 connector in Figure 2 is a communication port for Leadshine software connection. It is just used to modify parameters,
not for equipment control because neither precision nor stability is sufficient. If you need a Modbus-RS485 control, please use
a Leadshine iCS-RS series integrated stepper motor.The interface definition is as follows:

3.3 LED Light Indication
There are two LED lights for iCS series motor, one is red and another is green. The GREEN one is the power indicator which
will be always on generally. The RED one is a protection indicator. It is off always when a iCS-17xx operates normally, but will
flash 1, 2 or 7 times in a 5-second period when error protection is enabled. Different number of flashes indicates different
protection types.

When above protections are active, the motor shaft will be free and the red LED blinks. Reset the drive by repowering it to
make it function properly after removing above problems.
4. DIP Switch Configurations
The iCS series has a row of DIP switches, but the iCS17xx and iCS-23xx DIP switches are a bit different, as follows
