Function description:
The drive outputs this signal when the motor speed is close to zero.
Instructions:
The so-called “speed closed to zero” means that the motor speed is less than the threshold set
by the parameter “vel_stop”. In addition, this feature has the hysteresis of 12 rpm to avoid the
bounce of ZSPD output signal. The parameter “vel_stop” refers to Section 8.3.
