Motor If a thermistor is connected to terminal 8, then the Analog Input 3 Mode
thermistor (07.015) parameter must be set to Thermistor Short Cct (7), Thermistor
set-up (8) or Therm No Trip (9).
The drive is able to perform either a stationary or a rotating autotune. The
motor must be at a standstill before an auto-tune is enabled. A rotating
autotune should be used whenever possible so the measured value of
power factor of the motor is used by the drive
WARNING
Autotune
To perform an autotune:
• Set Pr 00.040 = 1 for a stationary autotune or set Pr 00.040 = 2 for a
rotating autotune
• Close the Drive Enable signal (terminal 31). The drive will display
'Ready'.
• Close the run signal (terminal 26 or 27). The lower display will flash
'Autotune' while the drive is performing the autotune.
• Wait for the drive to display 'Ready' or 'Inhibit' and for the motor to
come to a standstill.
• Remove the drive enable and run signal from the drive.
Select 'Save Parameters' in Pr mm.000 (alternatively enter a value of
Save
1000 in Pr mm.000) and press red

digital input.
Run Drive is now ready to run

A rotating autotune will cause the motor to accelerate up to
base speed in the direction selected regardless of the
reference provided. Once complete the motor will coast to a
stop. The enable signal must be removed before the drive can
be made to run at the required reference.
