SP600 AC Drive User Manual

Important:

Rotate Tune is used when motor is uncoupled from
the load. Results may not be valid if a load is coupled
to the motor during this procedure.

If the drive fails to Autotune and generates a drive fault:

Step 1.

Press any function (F) key to acknowledge the fault.

Step 2.

Press the ESC key to return to the Main Menu.

Step 3.

Select the Diagnostics Menu (

Step 4.

Select View Fault Queue.

Step 5.

Clear the fault using

Step 6.

Return to parameter 61 to re-start the Autotune
procedure.

3 = Calculate: This setting uses motor nameplate data to
automatically set IR Voltage Drop and Flux Current Ref. When the
drive is initially powered up, the Autotune (61) parameter defaults to
Calculate. With this setting, any changes made by the user to Motor
NP Power (45), Motor NP Volts (41), or Motor NP Hertz (48)
activates a new calculation, which updates the IR Voltage Drop (62)
and Flux Current (5) parameters. This calculation is based on a
typical motor with those nameplate values. The Autotune parameter
does not reset to zero after this calculation is performed.
Calculations will continue to be performed every time motor
nameplate values are changed.

The value of volts dropped across the resistance of the motor stator
at rated motor current. Used only when Torque Perf Mode (53) is set
to Sensrls Vect or SV Economize. This value is set by the Autotune
procedure (61).

The value of amps for full motor flux. Used only when Torque Perf
Mode (53) is set to Sensrls Vect or SV Economize. This value is set
by the Autotune procedure (61).
