Fault Detection - YASKAWA CIMR-F7Z44P0 User Manual

Fault Detection

When the Drive detects a fault, the fault information is displayed on the digital operator, the fault contact closes, and the motor
coasts to stop. (However, a fault with selectable stopping method will operate according to the stopping method selected.)
• If a fault occurs, take appropriate action according to the table by investigating the cause.
• To restart, reset the fault with any of the following procedures:
• Turn ON the fault reset signal.
• Set "14: Fault Reset" to a multi-function digital input (H1-01 to H1-05).
• Press the RESET key of the digital operator.
• Shut off the Drive input power once, and then turn on again.
The Run Command (Start Command) needs to be removed prior to resetting a fault. Resetting a fault by
removing and reapplying power to the Drive while the Run Command is applied, may cause the Drive to start
