500.0
50.0 (60.0)
Hz / RPM
Maximum output frequency or motor speed limit set in Hz or RPM.
The maximum possible value is limited by the lower of the following :-
- 500.0Hz maximum limit
- If P-10 >0, (500 x 120) / Motor Poles RPM
- P-17 / 16 Hz
Note
When P-10>0, slip compensation is automatically enabled, and P-01 is corrected to the synchronous speed of the motor.
P-02

Hz / RPM
Minimum speed limit – Hz or RPM. If P-10 >0, the value entered / displayed is in RPM
P-03

Energy Optimisation
0

0
-
Enables / Disables the Energy Optimisation function as follows.
Motor Energy Optimisation: Reduces energy losses in the motor under part load conditions by reducing motor flux. This function
should not be used in applications which have large sudden load step changes, or for PI control applications, as it may cause
instability in the control or over current trip.
Optidrive Energy Optimiser: Reduces the energy losses in the drive at higher output frequencies by reducing switching losses. This
may lead to vibration or instability in the motor under light load conditions.

Motor Rated Voltage / Back EMF at rated speed (PM / BLDC)
0
250 / 500
230 / 400
V
For Induction Motors, this parameter should be set to the rated (nameplate) voltage of the motor (Volts).
For Permanent Magnet or Brushless DC Motors, it should be set to the Back EMF at rated speed.
P-08
Motor Rated Current
Drive Rating Dependent
A
This parameter should be set to the rated (nameplate) current of the motor. This parameter cannot be adjusted greater than the
continuous current rating of the drive.
When the motor nameplate value is entered, thermal overload protection is enabled, as described in section 11.7.4
P-09
Motor Rated Frequency
10
500
50 (60)
Hz
This parameter should be set to the rated (nameplate) frequency of the motor
P-10
Motor Rated Speed
0
30000
0
RPM
This parameter can optionally be set to the rated (nameplate) RPM of the motor. When set to the default value of zero, all speed
related parameters are displayed in Hz, and the slip compensation for the motor is disabled. Entering the value from the motor
nameplate enables the slip compensation function, and the Optidrive display will now show motor speed in estimated RPM. All
speed related parameters, such as Minimum and Maximum Speed, Preset Speeds etc. will also be displayed in RPM.
Note If P-09 value is changed, P-10 value is reset to 0.
