Parameter Description Value range Factory
setting Explanation
P-01 Max. speed P-02 to 5 × P-09 (max. 500 Hz) 500 Hz
1)
Upper speed limit in Hz or rpm (see P-10 )
P-02 Minimum speed 0 – P-01 (max. 500 Hz) 0 Hz Lower speed limit in Hz or rpm (see P-10 )
P-03 Acceleration
ramp(s) 0 – 600 s 5 s Acceleration ramp time from 0 to 50 Hz (fixed) in
seconds.
P-04 Deceleration
ramp(s) 0 – 600 s 5 s Deceleration ramp time of 50 Hz (fixed) until
standstill in seconds. When set to 0, the fastest
possible ramp time without error is activated.
P-05 Stop mode
selection In the event of power failure:
0: Maintaining operation
1: Motor coasts to a halt
2: Rapid stop along
P-24
Normal stop:
0: Stop along ramp P-04
1: Motor coasts to a halt
2: Stop along ramp
P-04
0 In the event of a power failure, the inverter
attempts to move along the set ramps and then
switches off the output stages. With P-05, the
inverter attempts to maintain operation by reduc-
ing the motor speed and using the load as a gen-
erator.
P-06 Energy saving
function 0 Off
0
Automatically reduces the motor voltage with light
loads, if activated. In this case, the smallest possi-
ble motor voltage is 50% of the nominal voltage.
1 On
P-07 Nominal motor
voltage 0.20 – 250 V 230 V Rated voltage (nameplate) of the motor in volts.
For low-voltage drives, this value is limited to
250 V. When set to 0, voltage compensation is
disabled.
0.20 – 500 V 400 V

P-08 Nominal motor
current 25 – 100% of the inverter output
current DR motor
rating Rated current (nameplate) of the motor in
amperes.
P-09 Nominal motor
frequency 25 – 500 Hz 50 Hz Nominal frequency (nameplate) of the motor.
P-10 Nominal motor
speed 0 – 30000 rpm 0 When set to a value unequal 0, all speed-related
parameters are displayed in rpm. Activates slip
compensation when the motor speed (nameplate)
is set.
P-11 Additional volt-
age/boost 0 – 20% of the max. output volt-
age. Resolution 0.1%
• Size 1 max. 20%
• Size 2 max. 15%
• Size 3 max. 10%

low speeds by a value that can be set in order to
facilitate the breaking away of "jammed" loads. A
motor with forced cooling fan must be used for
continuous duty at low speeds.
