4.25 Power failure stop functions (Pr. 261 to Pr. 266)

4.25.1 Power-failure deceleration stop function (Pr. 261 to Pr. 266
When a power failure or undervoltage occurs, the inverter can be decelerated to a stop.
Remove the jumpers from across terminals R-R1 and S-S1, and connect terminal R1 to terminal P and
terminal S1 to terminal N.
