Protective and Diagnostic Functions<br />
Errors Interrupting Inverter Output<br />
• If the Inverter detects an error, the Inverter will have an error contact<br />
output and decelerate the motor to a stop, make the motor coast to a<br />
stop, or let the motor continue rotating according to the error processing<br />
mode selected while the Digital Operator displays the status of<br />
the error.<br />
• If an error results, refer to the following and take the necessary action.<br />
• Before restarting the Inverter, take one of the following actions to reset<br />
the Inverter.<br />
Turn ON an error reset signal by setting the multi-function input parameter used by the Inverter<br />
to 4.<br />
Press the STOP/RESET Key.<br />
Turn the main circuit power supply OFF and ON.<br />
Errors and Actions Taken<br />
Data<br />
Description<br />
display<br />
%c Overcurrent (OC)<br />
The Inverter output current<br />
instantaneously exceeded the<br />
overcurrent detection level.<br />
gf Ground fault (GF)<br />
A ground fault current<br />
exceeding 50% of the rated<br />
Inverter output current flowed<br />
from the output side of the<br />
Inverter.<br />
puf Fuse pre-arcing (PUF)<br />
The fuse of the main circuit<br />
blew out.<br />
sc<br />
Load short-circuit (SC)<br />
The Inverter output or load is<br />
shorted.<br />
Cause and action<br />
The output side of the Inverter is shorted or grounded<br />
due to motor coil burnout, poor motor coil insulation, or<br />
cable damage.<br />
The load is excessive. The acceleration and deceleration<br />
time settings are too short.<br />
A special motor or a motor with a capacity exceeding the<br />
maximum output capacity of the Inverter is used.<br />
The magnetic contactor on the output side of the Inverter<br />
was opened and closed.<br />
→ Determine the cause of the error, take the necessary<br />
action, and reset the system.<br />
The output side of the Inverter is grounded due to the<br />
motor coil burnout, poor motor coil insulation, or cable<br />
damage.<br />
→ Determine the cause of the error, take the necessary<br />
action, and reset the system.<br />
The output transistor is broken, in which case replace the<br />
Inverter. The output transistor will break if the B1 or<br />
negative terminal is shorted with the T1 (U), T2 (V), or T3<br />
(W) terminal.<br />
The output side of the Inverter is shorted or grounded.<br />
→ Determine the cause of the error, take the necessary<br />
action, and reset the system.<br />
The output side of the Inverter is shorted or grounded<br />
due to motor coil burnout, poor motor coil insulation, or<br />
cable damage.<br />

action, and reset the system.
