Troubleshooting Operation Problems and potential solutions. Refer to Section 5.4 for additional Diagnos-
tics Solutions. Additional troubleshooting of learn procedures are listed as well at the end of this section.
Problem Cause/Solution/Troubleshoot
Motor Does Not Move Check the Motor Current. Refer to Motor Draws High Current for
additional troubleshooting.
Make sure the brake is picking and/or not dragging.
Make sure speed is set correctly in LS02.
Check the Inverter Status to determine whether there is indication a run
command is being given (i.e. Up/Down Constant Speed/Acceleration/
Deceleration, etc.).
Check Input Status to determine whether the correct inputs are being
signaled for a run command.
Check the Command Speed to determine what the dictated speed com-
mand is.
Check the Active Speed and Active Prole to determine what speed set-
ting is being selected.
For digital inputs, check setting of the selected Active Speed or Ac-
tive Prole.
For analog speed commands, check the Raw and Processed (Ana-
log) Patterns, the High Speed setting, and speed settings for any
Active Prole.
Check to make sure the speed control gains (KP, KI Offset) are not set
too low.
For open loop induction motors, the Low Speed Torque Boost may
need to be increased to lift the load or decreased if either the Maximum
Torque of Inverter Peak Current limit is reached.
