9 Troubleshooting
Check point and remedy reference
Measure the ambient temperature.
→ Reduce the ambient temperature.
Check that the motor cooling system is oper-
ating correctly.
→ Replace or repair the motor cooling sys-
tem.
Measure the output current.
→ Reduce the load (use the Overload early
warning 2 Level (OL2)
(3005Hex-23Hex), and reduce the load
before an overload occurs.) (During win-
ter, the load may increase.)
→ Reduce the ambient temperature.
→ Increase Carrier Frequency
(3004Hex-1BHex).
Check the PTC thermistor specifications, and
recalculate the detection voltage.
→ Change the parameter data.
Check the 3004Hex-0AHex* data, and read-
just so that this does not stall even if data is
lowered.
→ Adjust 3004Hex-0AHex*.
Check that 1st Base Frequency
(3004Hex-05Hex*) and 1st Rated Voltage at
Base Frequency (3004Hex-06Hex*) match
the rated nameplate value.
→ Match these to the rated nameplate val-
ue.
While not using PTC thermistor, the Thermis-
tor Function Selection (MOH)
(3008Hex-1BHex*) is in an operation state.
→ Change Thermistor Function Selection
(MOH) (3008Hex-1BHex*) to 0 (Disa-
ble).
Reduce the frequency at which the power
supply is turned OFF and then ON.
→ Turn OFF and then ON less than once
every 30 minutes.
An error is generated each time the power
supply is turned OFF and then ON.
→ The inrush current protection circuit is
damaged. Request repair.
