Chapter 4 Explanation of Functions

(2)Output of the alarms for instantaneous power failure and undervoltage in the stopped state Use function "b004" to specify whether to output an alarm when instantaneous power failure or undervoltage occurs.

The inverter outputs the alarm providing the control power remains in the inverter.

Output of the alarms for instantaneous power failure and undervoltage in the stopped state Examples 5 to 7 show the alarm output operations with standard settings. Examples 8 to 10 show the alarm output operations with the settings to supply DC power (P-N) to control power supply terminals R0 and T0.

Note 1: You can assign the instantaneous power failure alarm signal (IP: 08) and the undervoltage alarm signal (UV: 09) to any of the intelligent output terminals [11] to [15] (C021 to C025) and the alarm relay terminal (C026) to output the alarm signals.

Note 2: For the alarm output following the occurrence of power failure of 1 second or longer, see the explanation of reset (Section 4.2.48).
