Ajust PI current loop parameters manually in 590+ DC parker

Before trying to do that, I would try to make the autotune work.  Setting these parameters manually is difficult and error-prone.  If autotune fails, consider these troubleshooting tips:

• Make sure the shaft did not rotate.  If it did, try clamping it down.  This is especially true of permanent magnet or stab shunt wound motors.
• Run a megohmeter test on your armature to make sure there are no shorts.
• Make sure you were running an armature current loop autotune and not a field current loop autotune.  Never run a field current loop autotune.

On the 590+, autotune should always succeed except in certain cases where the motor is very large -- over 500 HP.  Some motors can also be run without autotune.  Are you able to get this motor to run at all?  When you try running without autotune, what kind of fault do you get?
