Description
Flux level is limited during the braking. Deceleration time is
longer compared to full braking.
Maximum braking power. Almost all available current is used
to convert the mechanical braking energy to thermal energy in
the motor.
Defines the source of flux reference.
Note: This is an expert level parameter and should not be
adjusted without appropriate skill.
None.
Parameter 97.07 User flux
Source selection (see Terms and abbreviations
Defines the flux reference when parameter
reference select is set to User flux
User-defined flux reference.
This parameter can be used to improve the control dynamics
of a synchronous reluctance motor or a salient permanent
magnet synchronous motor.
As a rule of thumb, define a level to which the output torque
must rise with minimum delay. This will increase the motor
current and improve the torque response at low speeds.
Optimizer torque limit.
An optimization setting for balancing between control
performance and motor noise level.
Notes:
• This is an expert level parameter and should not be
adjusted without appropriate skill.
• Other settings than Normal
the rating data in the Hardware manual of the drive.
Control performance optimized for long motor cables.
Minimizes motor noise.
Control performance optimized for cyclic load applications.
This setting is to be used by ABB-authorized service
personnel only.
Enables signal injection. A high-frequency alternating signal is
injected into the motor at low speeds to improve the stability of
torque control. Signal injection 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.
Signal injection disabled.
Signal injection enabled with an amplitude level of 5%.
Signal injection enabled with an amplitude level of 10%.
Signal injection enabled with an amplitude level of 15%.
Signal injection enabled with an amplitude level of 20%.
