The standard motor control mode of the
Optidrive E3 is Sensorless Vector. By default,
the E3 uses the motor parameters for this
mode. However, low-speed torque can be
improved further by performing an “Autotune”.
The Autotune process improves performance
by building a model of the motor. This requires
the Inverter to operate the motor for a few
seconds to gather the necessary data.
To fully enable Sensorless Vector control by
performing anAutotune, first set the parameter
values specified in 8.1 (below) and then
complete the steps described in 8.2 and 8.3.
If Sensorless Vector control is not desired,
change parameter P-51 from 0 to 1 to disable
Sensorless Vector control and set the motor
control mode to simple V/f.
Parameter
Description
How to set
P-14
Extended Menu Access Code
Default is 0; set to to gain access to “advanced” parameters (P-15 to P-60).201
P-07
Motor Rated Voltage (V)
Rated Voltage of the motor. Set to match the motor nameplate eg V230
P-08
Motor Rated Current (A)
Rated current of the motor. Set to match the motor nameplate eg A2.4
P-09
Motor Rated Frequency (Hz)
Rated frequency of the motor. Default is Hz; change to suit the motor.50
P-10
Motor Rated Speed (rpm)
Rated rpm of the motor. Set to match the motor nameplate eg rpm (min-1)1460
P-51
Motor Control Mode
Default is for (Sensorless) Vector Control Mode. Default is required for this example.0
To disable Sensorless Vector mode set to 1 to change to simple V/f mode.
8.1 Parameters to check prior to an Autotune.
Easy Start Guide
8.2 Start Autotune.
Once the parameters in 8.1 have been set, select
parameter P-52 and press the navigate key to edit the
value.
Use the up and down keys to change the value from 0 to
1 then press the navigate key again to start the
Autotune.
8.3 The Autotune process.
When complete, the value of P-52 will return to 0.
There is no visible indication that an Autotune is in
progress but motor excitation noise will be heard for a
few seconds whilst the required values are measured.
Press and hold the navigate key for approx. 2 seconds
to return to the main operating display.
