490 Parameters
Defines the level of flux braking power. (Other stopping and
braking modes can be configured in parameter group
(page
Note:
This is an expert level parameter and should not be
adjusted without appropriate skill.
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
Defines the source of flux reference.
Note:
This is an expert level parameter and should not be
adjusted without appropriate skill.
Zero
None.
0
User flux reference
1
Source selection (see
). -
Defines the flux reference when parameter
is set to
100.00%
0.00 … 200.00%
User-defined flux reference.
100 = 1%
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%
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
No.
