Chapter 5 - Troubleshooting & Maintenance
A fault signal is output when an error occurs to the control circuitry of the
inverter. There are the Wdog error, the EEP error, and the ADC Offset for this
fault
This fault is displayed when the inverter cannot communicate with the keypad.
According to the I/O-48 [Operating Method when the Frequency Reference is
Lost] setting, there are three modes: continue operation, decelerate and stop,
and free run,
LOP: Displayed when option frequency reference is lost (DPRAM time out)
LOR: Displayed when option frequency reference is lost (Communication
network fault)
LOV: Displayed when 'V1' analog frequency reference is lost.
LOI: Displayed when 'I' analog frequency reference is lost.
LOX: Displayed when sun-board (V2, ENC) analog frequency reference is lost.
The inverter turns off its output when the output current of the inverter flows
more than the rated level (150% for 1 minute, 200% for 0.5 seconds).
Inverter uses NC thermal sensor for detecting heat sink temperature. If this
message is displayed, the thermal sensor wire may be cut. (Inverter keeps
operating)
