TROUBLESHOOTING
PROBLEM
POINT TO BE
CORRECTIVEACTION
CHECKED
Motor does not run
Incorrect Wiring
1. Check the power and control connections. For example the digital inputs DIX
programmed for Start/Stop, General Enable and No External Fault must be
connected to +24 V. For factory default programming, XC1:1 (DI1) must be
connected to +24 V(XC1:9) and XC1:10 connected to XC1:8.
Analog Reference
1. Check if the external signal is properly connected.
(if used)
2. Check the status of the speed potentiometer (if used).
Incorrect Programming
1. Check if the parameters are properly programmed for the application.
Fault
1. Check if the inverter is not disabled due to a Fault condition (Refer to table 7.1).
2. Check if there is a short-circuit between terminals XC1:9 and XC1:10 (short-
circuit at 24 Vdc power supply).
Motor Stall
1. Reduce the motor load.
2. Increase P169/P170 or P136/P137.
