To set threshold value for zero speed clamp detection.
Zero speed clamp detection (ZSP) output signal valid when motor speed goes under the value set
in Pr4.34
-
Disregard the direction of rotation,
valid for both directions.

If the difference between velocity command and motor actual speed is below Pr4.35, Velocity
coincidence (V-COIN) output signal valid.
Due to 10RPM hysteresis:
Velocity coincidence output OFF -> ON timing (Pr4.35 -10) r/min
Velocity coincidence output ON -> OFF timing (Pr4.35 +10) r/min
