TOPVERT G1/H1/P1 Series
E-33
IGBT fault (SC) {04}
IGBT module switching failure
is detected.
Check whether the motor’s resistance and insulation
are functioning right
Check whether the connection to the motor is short
circuited
Disconnect the cable between the drive and
motor,then run again, If the fault code is still displayed
then IGBT module should be failure---please return to
the factory
Wait for 60 seconds then execute RESET action to
reactivate the operation.
Drive overload (Ol) {05}
The drive detects excessive
drive output current.
G1, H1 Series: The drive can
withstand up to 150 % of the
rated current for a maximum
of 60 seconds.
P1 Series: The drive can
withstand up to 125% of the
rated current for a maximum
of 60 seconds.
Check whether the motor is overloaded
Reduce torque compensation setting as set in Pr5-01
Increase the acceleration time
Replace the drive with the next higher power model
Motor overload
-Thermal relay 1
(oL1) {06}
(Electronic thermal relay 1
protection.)
Check whether the motor 1 V/F setting proper
Check whether the motor 1 running low speed for
long period
Check for possible motor 1 overload
Check motor 1 full load current (Pr5-00)
Check electronic thermal overload 1 setting (Pr5-18 to
Pr5-19)
Reduce the load so that the drive output current does
not exceed the value set on Pr5-00
Increase motor capacity
Over-Torque1 detected
(ot1) {07}
Check whether the motor 1 is overloaded
Check whether motor 1 rated current setting (Pr5-00)
is suitable
Check whether the Over-Torque1 detect parameter
are suitable (Pr5-15~Pr5-17)
Check whether the mechanical system is normal
Increase motor 1 capacity and replace the drive with
the next higher power model
Over-current during constant
speed
(oCn) {08}
Check for possible poor insulation at the output wires
Check for possible motor stall
Replace the drive with the next higher power model.
Over-current during
acceleration
(oCA) {09}
Check for possible poor insulation at the output wires
Decrease the torque boost setting in Pr5-01
Increase the acceleration time
Replace the drive with the next higher power model.
Over-current during
deceleration
(oCd) {10}
Check for possible poor insulation at the output wires
Increase the deceleration time
Replace the drive with the next higher power model
EPROM read error
(EP1) {11}
Check whether the power voltage falls within the rated
voltage
