instruction manual for the drive.
Faults
■
Both bUS (PROFIBUS-DP Option Communication Error) and EF0 (External Fault Input
from the PROFIBUS-DP Option) can appear as an alarm or as a fault. When a fault occurs,
the digital operator LEDs remain lit. When an alarm occurs, the digital operator LEDs flash
and the ALM light turns
If communication stops while the drive is running, answer the following questions to help
remedy the fault:
• Is the PROFIBUS-DP Option properly installed?
• Is the communication line properly connected to the PROFIBUS-DP Option? Is it loose?
• Is the controller program working? Has the controller CPU stopped?
• Did a momentary power loss interrupt communications?
