No. Name Default Selection
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
P184 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.
P187 (2) 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
1 Braking with BUS threshold
2 Braking always on with
deceleration
3 Braking with bus regulator
4 Special (Consult factory
before using)
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)
P194 Password 225 0000 9999 • Must enter password to access
parameters
• P194 = 0000: Disables password
(2) Parameter applicable to models 15HP (11kW) and higher.
