Parameters 349
An optimization setting for balancing between control
performance and motor noise level.
Note:
This is an expert level parameter and should not be
adjusted without appropriate skill.
Normal
Control performance optimized for long motor cables.
0
Low noise
Minimizes motor noise.
Note:
This setting requires derating. Refer to the rating
data in the
Hardware manual
.
1
Cyclic
Control performance optimized for cyclic load applications.
Note: This setting is not suitable for long motor cables.
2
Custom
This setting is to be used by ABB-authorized service
personnel only.
Note:
This setting may require derating. Refer to the rating
data in the Hardware manual.
3
Enables the anti-cogging function: a high-frequency
alternating signal is injected to the motor in the low speed
region to improve the stability of torque control. This
removes the “cogging” that can sometimes be seen as the
rotor passes the motor magnetic poles. Anti-cogging can
be enabled with different amplitude levels.
Notes
:
• This is an expert level parameter and should not be
adjusted without appropriate skill.
• Use as low a level as possible that gives satisfactory
performance.
• Signal injection cannot be applied to asynchronous
motors.
Disabled
Anti-cogging disabled.
0
Enabled (5 %)
Anti-cogging enabled with amplitude level of 5%.
1
Enabled (10 %)
Anti-cogging enabled with amplitude level of 10%.
2
Enabled (15 %)
Anti-cogging enabled with amplitude level of 15%.
3
Enabled (20 %)
Anti-cogging enabled with amplitude level of 20%.
4
Rotor time constant tuning.
This parameter can be used to improve torque accuracy in
closed-loop control of an induction motor. Normally, the
motor identification run provides sufficient torque accuracy,
but manual fine-tuning can be applied in exceptionally
demanding applications to achieve optimal performance.
Note:
This is an expert level parameter and should not be
adjusted without appropriate skill.
100%
25…400%
Rotor time constant tuning.
1 = 1%
No.
