Performing a Stationary Autotune
Note
The drive will not perform an Autotune when in Volts/Hz Mode (Open-Loop Drive.) An Autotune is not
necessary in this control mode.
Before starting the stationary Autotune, you
MUST
enter the value of magnetising current for the motor.
This may be available on the motor nameplate. If not, you may need to contact the motor supplier.
1.
In the SET/QUICK SETUP menu, set the AUTOTUNE MODE parameter to STATIONARY (0).
2.
Set ENABLE to TRUE, and start the drive
. The drive will carry out a stationary Autotune, injecting
current into the motor but not turning the shaft. The Run and Stop led’s will flash. When complete, the
drive is returned to the stopped condition and the AUTOTUNE ENABLE parameter is reset to FALSE.
IMPORTANT
Now perform a SAVE CONFIG to save your new settings. Refer to Chapter 8: “The Keypad” -
SAVE CONFIG.
•
If the drive is configured to run in Sensorless Vector mode, set-up is complete.
•
If the drive is configured to run in Closed-loop Vector mode, i.e. using an encoder, then the encoder
direction must be set up. Refer to “Setting the Encoder Sign” below.
