Function:
active when 1-73 Flying Start is enabled. This
parameter is only available in VVC
Function:
Control the percentage of the frequency for
the pulses used to detect the motor
direction. Increasing this value will reduce
the generated torque. 100% means 2 times
the slip frequency. The parameter is active
when 1-73 Flying Start is enabled. This
parameter is only available in VVC

calculated automatically, i.e., on the
basis of the rated motor speed n
This function is not active when
1-00 Configuration Mode is set to Speed
closed-loop [1] or Torque [2] Torque
control with speed feedback or when
1-01 Motor Control Principle is set to U/f
[0] special motor mode.
Function:
[0.05 - 5.00 Enter the slip compensation reaction

s] speed. A high value results in slow
reaction, and a low value results in
quick reaction. If low-frequency
resonance problems arise, use a
longer time setting.
[0 - 500 %]
Function:
[5 - 50 ms] Set 1-64 Resonance Dampening and
1-65 Resonance Dampening Time Constant to
help eliminate high-frequency resonance
problems. Enter the time constant that
provides the best dampening.
