Installing the Drive
AC890PX AC Drive
Step 4: Run the Motor
WARNING
Remove the fuses (or trip the circuit breaker) on your 3-phase supply.
Make sure the power is OFF, and that it cannot be switched on accidentally whilst you are working.
Allow at least 10 minutes for the drive's capacitors to discharge to safe voltage levels (<50V).
4.1: The Autotune Feature
NOTE
You MUST carry out an Autotune, unless the drive is in Volts/Hz Mode (Open-Loop Drive) or in PMAC control mode
(Autotune will not perform in these modes as it is unnecessary - go to page 3-43).
The Autotune feature identifies motor characteristics to allow the drive to control the motor.
It loads the values into the parameters below, which are in the QUICK SETUP menu.
