Goodrive3000 series medium voltage VFD
During ACC running of the VFD, due to heavy load, the actual increasing ratio of the motor speed is lower
than the increasing ratio of output frequency. The trips of the VFD will be caused by the ACC overcurrent
fault if there are not any measures.
During the running of the VFD, this function will detect the output current and compare it with the limit
level defined in P11.06. If it exceeds the level, the VFD will run at stable frequency during ACC running,
while the VFD will derate to run during the constant running. If it exceeds the level continuously, the
output frequency will keep decreasing to the lower limit. If the detected output current is lower than the
limit level, the VFD will continue ACC running.
