302 Parameters
97.05 Flux braking Defines the level of flux braking power. (Other stopping
and braking modes can be configured in parameter group
21 Start/stop mode).
Note: This is an expert level parameter and should not be
adjusted without appropriate skill.
Disabled
Disabled Flux braking is disabled. 0
Moderate Flux level is limited during the braking. Deceleration time
is longer compared to full braking.
1
Full Maximum braking power. Almost all available current is
used to convert the mechanical braking energy to thermal
energy in the motor.
WARNING! Using full flux braking heats up the
motor especially in cyclic operation. Make sure
that the motor can withstand this if you have a
cyclic application.

97.10 Signal injection 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
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
97.11 TR tuning 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.
