Non-Stop On Momentary Power Interruption - Omron RX2 Series User Manual

(Ex.6) When [bb-23] ≠00 and [bb-30] = 04, it restarts by picking up the frequency, and then after decel-
eration according to the setting, the motor trips when stopped.

Non-stop on Momentary Power Interruption

This function allows deceleration and stop of the motor while maintaining the voltage under the over-
voltage level when the power supply is shut down during operation.
One of the three modes can be selected with [bA-30] instantaneous power failure non-stop selection.
Precautions for Correct Use
• Instantaneous power failure non-stop operation is activated when the input to the main power
supply (R, S, T) drops.
• When [bA-30] is 01 or 02, the motor decelerates and stops after the function is activated. You
need to turn off the operation command and turn it on again to restart after the stop. Even if
the [bA-30] is 03, you still need to turn off the operation command and turn it on again if the
motor decelerated and stopped without recovery after the function is activated.
• If the control power supply (R0, T0) is not input separately from main power supply, supply
the P-N voltage to the control power supply (R0, T0) to use the instantaneous power failure
non-stop function. When using this function, disconnect the J51 connector line connected to
the R0 and T0 terminals and connect the wire from main terminal P to R0, and N to T0. Use
electrical wire of 0.75mm
