6. Parameters

6.1. Standard Parameters

Par. Description
P-01 Maximum Frequency / Speed Limit
Maximum output frequency or motor speed limit – Hz or RPM. If P-10 >0, the value entered / displayed is in RPM.
P-02 Minimum Frequency / Speed Limit
Minimum speed limit – Hz or RPM. If P-10 >0, the value entered / displayed is in RPM.
P-03 Acceleration Ramp Time
Acceleration ramp time from zero Hz / RPM to base frequency (P-09) in seconds.
P-04 Deceleration Ramp Time
Deceleration ramp time from base frequency (P-09) to standstill in seconds. When set to 0.00, the value of P-24 is used.
P-05 Stopping Mode / Mains Loss Response
Selects the stopping mode of the drive, and the behaviour in response to a loss of mains power supply during operation.

P-06 Energy Optimiser
Motor Energy Optimisation is intended for use in applications where the motor operates for extended time periods at constant speed
with light load. It should not be used in applications with large, sudden step changes in load or for PI control applications.
Optidrive Energy Optimisation reduces the drive internal heat losses increasing efficiency however it may result in some vibration in the
motor during light load operation. In general, this function is suited to Fan, Pump and Compressor applications.

P-07 Motor Rated Voltage / Back EMF at rated speed (PM /
BLDC)
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
This parameter should be set to the rated (nameplate) current of the motor.
P-09 Motor Rated Frequency
6
This parameter should be set to the rated (nameplate) frequency of the motor.
P-10 Motor Rated Speed
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 (where motor speed is maintained at a constant value
regardless of applied load) 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 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.
