with zero speed. If the motor runs in low speed, adjust the parameter PA22 to make the
motor to be in zero speed state.
3) Slowly adjust the analog voltage, the motor speed will vary by the voltage variation. The
highest motor speed in ±10V input voltage can be adjusted by modifying parameter
PA29. Be attentive that the highest running speed is limited by PA23.
4) Modify parameter PA19 if the rotation direction is required to be changed.
When PA19=0, motor runs forward (CCW) for positive voltage, backward(CW) for
negative voltage;
When PA19=1, motor runs backward (CW) for positive voltage, forward(CCW) for
negative voltage;
5) If vibration occurs in the CNC closed loop running, adjust parameter PA08 for feedback
filtering.
