Forward/Reverse Run Command Input Error

What does EF mean?

Both forward run and reverse run commands have been received simultaneously and maintained for longer than 0.5 seconds. This is a sequence error that causes the motor to ramp to a stop, indicating conflicting commands from the control system.

• Simultaneous activation of both forward and reverse run commands for more than 0.5 seconds
• Improper control sequence for run commands from the PLC or control system

Click steps to track your progress.

1. 1

   Review the control sequence for forward and reverse run commands from the PLC or control system.

2. 2

   Verify that simultaneous activation of both forward and reverse commands for more than 0.5 seconds is prevented by control logic or wiring.

3. 3

   Correct any identified sequence errors in the control program or wiring to ensure only one run command is active at a time.
