 You can select the enable condition of reset function (RES signal, reset command through communication) input.
 When Pr.75 is set to any of "1, 3, 15, 17", a reset can be input only when the drive unit is tripped.
NOTE
 When the reset signal (RES) is input during operation, the motor coasts since the drive unit being reset shuts off the
output.
 When reset is performed, cumulative values of electronic thermal O/L relay, regenerative brake duty are cleared.
 The reset key of the PU is only valid when the drive unit is tripped, independently of the Pr.75 setting.
