430 Parameters
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.

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.
User flux
reference
Zero None. 0
User flux reference Parameter 97.07 User flux reference.1
Other Source selection (see Terms and abbreviations on page 114). -
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.
Notes:
• This is an expert level parameter and should not be
adjusted without appropriate skill.
• Other settings than Normal may require derating. Refer to
the rating data in the Hardware manual of the drive.
Normal
Normal Control performance optimized for long motor cables. 0
Low noise Minimizes motor noise. 1
Cyclic Control performance optimized for cyclic load applications. 2
Custom This setting is to be used by ABB-authorized service
personnel only.

97.10 Signal injection 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.
Disabled
Disabled Signal injection disabled. 0
Enabled (5 %) Signal injection enabled with an amplitude level of 5%. 1
Enabled (10 %) Signal injection enabled with an amplitude level of 10%. 2
Enabled (15 %) Signal injection enabled with an amplitude level of 15%. 3
Enabled (20 %) Signal injection enabled with an amplitude level of 20%. 4
