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

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
