Table 3 Definition of Control Signal Port
Signal Functional Description
PLS+(CW+) Pulse signal. In the PLS+DIR control signal mode, the signal is the
pulse control signal and the rising edge is effective.
In the CW/CCW control signal mode, the signal is the forward rotation
control signal and the rising edge is effective. The high-level time shall
not be less than 1.25uS to ensure reliable response of the internal
optocoupler.
The maximum input frequency of the pulse signal is 400 KHz
PLS-(CW-)
DIR+(CCW+) In the PLS+DIR control signal mode, the signal is direction control
signal, and the driver sets the rotation direction of the motor by
detecting the level of this signal. The signal value of the effective
moment in the rising edge of pulse signal.
In the CW/CCW control signal mode, the signal is the reverse rotation
control signal and the rising edge is effective. To ensure reliable
response of the internal optocoupler, the high-level time in this mode
shall not be less than 1.25uS.
The maximum input frequency of the pulse signal is 400 KHz
DIR-(CCW-)
FREE+ This signal is offline signal. If the signal is at a high level, the driver
turns off the power supply for the motor, and the motor rotor turns into
Free status (Offline). Adequate measures must be adopted to prevent
the motor from causing equipment damage or personal injury when it
is in the offline status.

ERR+ Alarm output signal. This signal port is the optocoupler output port for
open collector. When the driver has an exception alarm or power
failure alarm, this signal port have not outputs((level determined by the
external circuit).
For this port, the maximum allowable input voltage is 30V DC and the
maximum supply current is 10 mA.
