High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
• If the inverter detects a power supply shutoff during operation, this function causes the motor to stop
after deceleration so that the internal DC voltage of the inverter is maintained at the Deceleration
Hold Level on Power Interruption (b052).
• This function can be enabled in three ways in the Deceleration Stop Selection on Power Interruption
(b050).
• This function does not reset until the motor stops running. To restart the inverter after power recovery
with this function activated, turn ON the STOP command input (to turn OFF the RUN command OFF)
and then turn ON the RUN command input again.
