Motor Control Parameters
Motor Control Parameters
This section gives information on various parameters which are used to control the motor.
Overview
As default, the Optidrive E3 is set up in a simple vector control mode (parameter P-51 = 0). For most open
loop, general purpose applications, this mode gives good motor starting torque performance without the need
for any complex set up.
For some applications which have a high starting torque requirement, this mode along with carrying out an
autotune on the motor will give good motor torque performance.
For some applications which are even more demanding, parameter P-11, Low Frequency Torque Boost, can be
adjusted to try to give even better starting torque performance.
The Optidrive E3 can also be used for fan and pump applications. The E3 has a number of settings which can
be used to help with energy saving in fan and pump type applications.
The following section of this User Guide gives information on the various parameters that can influence motor
performance.

Parameter P-06 = 0
With both the motor energy optimizer and Optidrive E3 energy optimizer disabled, the drive will output a
linear V/f (Voltage to frequency) characteristic.
Motor Energy Optimiser
This is intended for use in applications where the motor operates for extended timer periods at constant
speed with light load. The E3 will automatically adjust its output voltage based on motor load to reduce motor
energy consumption.
Optidrive E3 Energy Optimisation
This function reduces the drives internal heat losses increasing efficiency. However this may result in some
vibrations in the motor during light load operation.
NOTE: P-06 can be used for fan and pump applications when P-13 is not used.
NOTE: P-06 should not be used on dynamic applications where the load changes quickly.
