Troubleshooting
Warning 34 Appears even though Communication is Established
If the PLC is in stop mode Warning 34 will appear. Check that the PLC is in run mode.
Drive Will Not Respond to Control Signals
Check 1: Is the Control word valid?
If bit 10=0 in the Control word, then the drive will not accept the Control word, because the default setting
is bit 10=1. Set bit 10=1 via the PLC.
Check 2: Is the relationship between bits in the Control word and the terminal I/Os correct?
Check the logical relationship in the drive.
Set the logic to bit 3=1 AND digital input=1 in order to achieve a successful start.
Define the desired logical relationship in par. 8-50 to 8-56 according to the following range of options. Select
the FC 300 control mode, digital input and/or serial communication, using par. 8-50 to 8-56.
The tables below show the effect upon the FC 300 of a coast command for the full range of par. 8-50 settings.
