The main circuit DC voltage becomes lower than the lower under-
voltage level before the motor starts.
The main circuit DC voltage becomes higher than the lower under-
voltage level before the motor starts.
The thermal protection contact is input to the external terminal.
Over torque is detected while the output current is larger than or equal to the
setting of Cn-26. However, the Sn-12 has been set such that the inverter
continue to run and disregard the over-torque warning.
Stall prevention operates while acceleration.
Stall prevention operates while running
Stall prevention operates while deceleration.
Forward and reverse rotation commands are simultaneously detected
for a period of time exceeding 500ms. (The inverter is stopped
according to the stop method preset by Sn-04.)
MODBUS Communication fault occurs. The inverter remains
operating.
Transmission fault of digital operator
External B.B. signal (terminal ) is input (The inverter stops and the
motors stops without braking)
Improper inverter capacity (Sn-01) setting.
Improper setting of multi-function input signal (Sn-25, 26, 27 and
28).
Improper setting of V/F characteristic (Cn-02~08)
Improper setting of Cn-18, Cn-19
Excessive speed (operation remains)
PG Open-circuit (operation remains)
Excessive speed deviation (operation remains)
Error during upload and download (operation remains)
Operator EEPROM error.
Data incorrect during Communication from the operator to the
inverter.
Data incorrect during Communication from the inverter to the
operator.
