.
9
MOT TEMP
Motor is too hot, based on either the drive’s estimate or on temperature
feedback.
• Check for overloaded motor.
• Adjust the parameters used for the estimate (3005…3009).
• Check the temperature sensors and Group 35 parameters.
10
PANEL LOSS
Panel communication is lost and either:
• Drive is in local control mode (the control panel displays HAND), or
• Drive is in remote control mode (REM) and is parameterized to accept
start/stop, direction or reference from the control panel.
To correct check:
• Communication lines and connections
• Parameter 3002
PANEL COMM ERROR
.
• Parameters in Group 10: Command Inputs and Group 11: Reference
Select (if drive operation is REM).
11
ID RUN FAIL
The motor ID run was not completed successfully. Check for and correct:
• Motor connections
12
MOTOR STALL
Motor or process stall. Motor is operating in the stall region. Check for and
correct:
• Excessive load.
• Insufficient motor power.
• Parameters 3010…3012.
