1-58 Flystart Test Pulses Current
Range:
Function:
active when
1-73 Flying Start
is enabled. This
parameter is only available in VVC
plus
.
1-59 Flystart Test Pulses Frequency
Range:
Function:
200 %
*
[0 - 500
%]
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
plus
.

1-62 Slip Compensation
Range:
Function:

Enter the % value for slip compensation
to compensate for tolerances in the
1-62 Slip Compensation
Range:
Function:
value of n
M,N
. Slip compensation is
calculated automatically, i.e., on the
basis of the rated motor speed n
M,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.
1-63 Slip Compensation Time Constant
Range:
Function:
Size related
*
[0.05 - 5.00
s]
Enter the slip compensation reaction
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.
NOTE!
1-63 Slip Compensation Time Constant
will not have effect
when
1-10 Motor Construction
= [1] PM, non-salient SPM.
1-64 Resonance Dampening
Range:
Function:
100 %
*
[0 - 500 %]
NOTE!
1-64 Resonance Dampening
will not have effect when
1-10 Motor Construction
= [1] PM, non-salient SPM.
1-65 Resonance Dampening Time Constant
Range:
Function:
5 ms
*
[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.
NOTE!
1-65 Resonance Dampening Time Constant
will not have
effect when
1-10 Motor Construction
= [1] PM, non-salient
SPM.
