● In heavy load (Pr.00-16=1), if the DC voltage is higher than the 875 V
DC
(575V series), 700 V
DC
(460V series) or
350 V
DC
(230 series), the maximum value for Pr.06-04 is 185%.
● This is a protection for the drive to decrease output frequency automatically when the motor overloads abruptly
during constant motor operation.
● If the output current exceeds the setting value for Pr.06-04 when the drive is operating, the drive decelerates
according to the Pr.06-05 setting to prevent the motor from stalling. If the output current is lower than the
setting value for Pr.06-04, the drive accelerates (according to Pr.06-05) again to the setting frequency.
