Reset selection [Pr. 75]
*1 This magnetic contactor is provided to prevent an automatic restart when power is restored after a power failure. Use the start
signal (ON or OFF of STF, STR) to make a start or stop.
*2 When the power supply is 400V class, install a step-down transformer.
*3 Set [Pr. 75 = 1] "Reset input is enabled only when the fault occurs" to disable resetting of the inverter during normal operation. (If
the inverter is reset during normal operation, the motor coasts to a stop. This setting is to prevent the inverter from resulting in
an alarm if the motor is still coasting when the inverter has returned from the reset status.)
*4 When using an external brake resistor or brake unit, remove the jumper from across PR-PX.
