Selection
No.
Disabled / uint16
Defines the level of flux braking power. (Other stopping
and braking modes can be configured in parameter
group
).
See section
.
Note: This is an expert level parameter and should not
be adjusted without appropriate skill.
Flux braking
97.5
0
Flux braking is disabled.
Disabled
1
Flux level is limited during the braking. Deceleration
time is longer compared to full braking.
Moderate
2
Maximum braking power. Almost all available current
is used to convert the mechanical braking energy to
thermal energy in the motor.
Full
User flux reference /
uint32
Defines the source of flux reference.
Note: This is an expert level parameter and should not
be adjusted without appropriate skill.

0
None.

100.00 % / real32
Defines the flux reference when parameter
is set to
.
User flux reference
97.7
100 = 1 % / 100 = 1 %
User-defined flux reference.
0.00 ... 200.00 %
0.0 % / real32
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 minimum
torque
97.8
10 = 1 % / 10 %
Optimizer torque limit.
0.0 ... 1600.0 %
Normal / uint16
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.
Note: Other settings than
may require derating.
Refer to the rating data in the hardware manual of the
drive.
Note: To improve the control performance, the
switching frequency reference is automatically
increased with ABB sine filter if the motor/drive current
ratio is less than 0.55.
Switching freq mode
97.9
0
Control performance optimized for long motor cables.
Normal
1
Minimizes motor noise.
Low noise
