EP24v
External Power 24V Supply
The voltage of the main circuit power supply
decreased, and the 24 V power supply is supplying
power to the drive.
•
Examine the main circuit power supply.
•
Turn ON the main circuit power supply to run the drive.
FbH
Excessive PID Feedback
The
FbH
detection level is set incorrectly.
Adjust
b5-36 [PID High Feedback Detection Lvl]
and
b5-37 [PID
High Feedback Detection Time]
.
There is a problem with the PID feedback wiring.
Correct errors with the PID control wiring.
The feedback sensor is not operating correctly.
Examine the sensors on the control device side.
A fault occurred in the feedback input circuit of the
drive.
Replace the control board or the drive. For information about
replacing the control board, contact Yaskawa or your nearest sales
representative.
FbL
PID Feedback Loss
The
FbL
detection level is set incorrectly.
Adjust
b5-13 [PID Feedback Loss Detection Lvl]
and
b5-14 [PID
Feedback Loss Detection Time]
.
HCA
High Current Alarm
The load is too heavy.
•
Decrease the load for applications with repetitive starts and
stops.
•
Replace the drive with a larger capacity model.
