490 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).
See section Flux braking (page 99).
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.
2
97.06 Flux reference
select
Defines the source of flux reference.
Note: This is an expert level parameter and should not be
adjusted without appropriate skill.
Par. 80.81
Zero None. 0
User flux reference Parameter 97.07 User flux reference.1
Other Source selection (see Terms and abbreviations on page 148). -
97.07 User flux reference Defines the flux reference when parameter 97.06 Flux
reference select is set to User flux reference.
100.00%
0.00 … 200.00% User-defined flux reference. 100 = 1%
97.08 Optimizer minimum
torque
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.
0.0%
0.0 … 1600.0% Optimizer torque limit. 10 = 1%
97.09 Switching freq
mode
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
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.
