Table 3 Definition of Control Signal Port
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
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
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.
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.
