Baldor MN1274 06/2001 Tuning, proportional gain manually and proceed to the feedback alignment

7.1.4Tuning

The following problems could occur when the software is performing automatic tuning tests. If the Ready LED is red during any of the tests see section 7.1.6 on page 91.

Check that the software can communicate with the MintDrive by typing PRINT DRIVEFAULT in the Terminal window. If no error is reported then communication can be achieved.

	Power-cycle the unit and repeat the test.
	Click the Calculate button and use this value or enter the Current

	Power-cycle the unit and repeat the test.
	Check the motor data settings (number of poles, resolver speeds
	etc.) have been entered correctly.
	Check the wiring of the feedback cable.
	Check that the resolver cable is physically separated from power
	cables. If the resolver cable has to cross power cables, check that
	they cross at an angle of 90 degrees.
	Enter the default angle of 23 degrees (for a 8-pole motor) or 46
	degrees for a 4-pole motor.
