> V
deceleration freeze
(114% of
the rated V
bus
), the flux brake will be turned ON.
2 Braking always on with deceleration As long as drive is in deceleration, the flux brake will be ON.
3 Braking with bus regulator When drive is in deceleration and V
bus
> V
deceleration freeze
(114%
of the rated V
bus
), the motor speed will be increased to reduce
the bus voltage. Determined by the value in P191, the speed
increment = slip speed * P191(%) / 37.
4 Special (Consult factory before using)
WARNING
Flux braking can cause heat in the motor. To avoid damage to the motor, use a PTC to
protect the motor. If the flux brake is used too frequently, the drive will trip fault “F_PF”.
p191 Motor Brake Level 0 0 {%} 75
(flux
braking
disabled)
Active when P190 > 0 and drive is in deceleration
mode. Use to reduce deceleration time on high
inertia loads.
NOTE: Over usage of P190 can cause frequent
‘overload’ trips “F.PF”
Not active for P300 = 5 (Torque mode)
p192 Motor Braking
Deceleration
Reduction Level 0.0 0 P167
(base freq)
Raising the value of P191 reduces the
drive deceleration rate during flux braking.
Active when P190 > 0 and P192 > 0.0, Drive is
in deceleration mode. Use to reduce deceleration
time on high inertia loads.
NOTE: Usage of P192 can cause the drive to
decelerate faster than settings in P105/P127.
Not active for P300 = 5 (Torque mode)

• Parameters are reset to the defaults listed in
this manual.
• For P199=4, the following exceptions apply:
- P103, P152, P161, P167 = 50.0 Hz
- P165 = 400V (400/480V drives only)
- P304 = 50 Hz
- P305 = 1450 RPM
- P107 = 0 (480 V drives only)

WARNING!
Modification of P199 can affect drive functionality! STOP and EXTERNAL FAULT circuitry may
be disabled! Check P100 and P121...P124
NOTE 1
If the EPM does not contain valid OEM settings, a flashing GF will be displayed when P199
is set to 1 or 2.
NOTE 2
When P199 is set to 1, the drive operates from the OEM settings stored in the EPM Module
and no other parameters can be changed (GE will be displayed if attempted).
NOTE 3
Auto Calibration is not possible when operating from OEM Settings.
