Probable causes and remedies
Meaning
OL3
Overtorque Det 1
There has been a current
greater than the setting in
L6-02 for longer than the
setting in L6-03.
→
Make sure that the settings in L6-02 and L6-03
are appropriate.
→
Check the mechanical system and correct the
cause of the overtorque.
OL4
Overtorque Det 2
There has been a current
greater than the setting in
L6-05 for longer than the
setting in L6-06.
→
Make sure that the current setting in L6-05 and
time setting in L6-06 are appropriate.
→
Check the mechanical system and correct the
cause of the overtorque.
OS
Over speed
The speed has been greater
than the setting in F1-08 for
longer than the setting in
F1-09.
•
Overshooting/Undershooting are occurring.
→
Adjust the gain again.
•
The reference speed is too high.
→
Check the reference circuit and reference gain.
•
The settings in F1-08 and F1-09 aren’t appropriate.
→
Check the settings in F1-08 and F1-09.
PGO
PG open
The PG is disconnected.
The Inverter is outputting a
frequency, but PG pulses aren’t
being input.
•
The is a break in the PG wiring.
→
Fix the broken/disconnected wiring.
•
The PG is wired incorrectly.
→
Fix the wiring.
•
Power isn’t being supplied to the PG.
→
Supply power to the PG properly.
•
The torque limit is set to 0 through CompoBus/D
communications. (Applies only to flux vector con-
trol.)
→
Set F9-05 to 0 (torque limit disabled).
DEV
Speed Deviation
The speed deviation has been
greater than the setting in
F1-10 for longer than the
setting in F1-11.
•
The load is too large.
→
Lighten the load.
•
The acceleration time and deceleration time are
too short.
→
Lengthen the acceleration time and decelera-
tion time.
•
The load is locked.
→
Check the mechanical system.
•
The settings in F1-10 and F1-11 aren’t appropriate.
→
Check the settings in F1-10 and F1-11.
•
The torque limit is set to 0 through CompoBus/D
communications. (Applies only to flux vector con-
trol.)
→
Set F9-05 to 0 (torque limit disabled).
