Keypad Setpoint
Single Press
Increment 0.1 0.1 100.0 Used for run screen setpoint editing only.
If P176 >0.1 then scrolling of keypad setpoint
is enabled.
p178
Display Frequency
Multiplier 0.00 0.00 650.00 • Allows frequency display to be scaled
• P178 = 0.00: Scaling disabled
• P178 > 0.00: Display = Actual Frequency
X P178
EXAMPLE
If P178 = 29.17 and actual frequency = 60 Hz, then Drive displays 1750 (rpm)
p179
Run Screen Display 0 0 {Parameter Number} 599 • 0 = Normal Run Screen, this display depends
on mode of operation. Refer to section 4.2.
• Other selections choose a diagnostic
parameter to display (P501…P599).
• Parameters P560 - P564 are selectable
if the sequencer is enabled (P700 is not
0). P560-P564 are not visible until P700
is enabled.

Oscillation
Damping Control 0 0 80 0 = Damping disabled
Compensation for resonances within drive
p181
Skip frequency 1 0.0 0.0 {Hz} 500 • Drive will not run in the defined skip range;
used to skip over frequencies that cause
mechanical vibration
• P181 and P182 define the start of the
skip ranges
• P184 > 0 defines the bandwidth of both
ranges.
p182
Skip frequency 2 0.0 0.0 {Hz} 500

Skip frequency
bandwidth 0.0 0.0 {Hz} 10.0
NOTE
Bandwidth (Hz) = f
s
(Hz) + P184 (Hz) f
s
= P181 or P182
EXAMPLE: P181 = 18 Hz and P184 = 4 Hz; skip range is from 18 to 22 Hz
p185
Voltage Midpoint
V/Hz characteristic 0 0.0 {V} P165 Valid only when P300 = 0 or 2.
Use with P187 to define midpoint on V/Hz
curve.

Frequency
Midpoint V/Hz
characteristic 0.0 0.0 {Hz} P167 Valid only when P300 = 0 or 2.
Use with P185 to define midpoint on V/Hz
curve.
p190
Motor Braking 0 Disabled
Flux brake OFF.
1 Braking with BUS threshold
When drive is in deceleration and V
bus
>
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)
