8.1.6 Dwell operation Chapter 8 Applied Functions Group Code No. Function Display Initial Value Setting Range Unit ADV 20 Acc Dwell Freq - 5.00 Starting frequency ~ Maximum frequency Hz 21 Acc Dwell Time - 0.0 0~10 Sec 22 Dec Dwell Freq - 5.00 Starting frequency ~ Maximum frequency Hz 23 Dec Dwell Time - 0.0 0~10 Sec If the operating command is input, the inverter operates at steady speed for the acceleration dwell time at the set acceleration dwell frequency and resumes acceleration. If the stop command is input, inverter operates at steady speed for the deceleration dwell time at the set deceleration dwell frequency after deceleration and then stops. If control mode (DRV-09 Control Mode) is used as the V/F mode, it can be used for opening the brake after operation at the dwell frequency before the mechanical brake is opened at the lifting load. * Detailed description about Dwell operation Caution Be careful that dwell operation at a frequency higher than the rated slip of the motor with the load shown in the case above might adversely affect the life of the motor or damage the motor due to over current through the motor.

It operates as set speed after the lapse of the Dwell acceleration run time (Acc Dwell Time) which is set in Dwell run frequency. If Stop command is input during run, inverter will decelerate as Dwell run frequency and then it will stop as previous deceleration time after the set Dwell deceleration run time (Dec Dwell Time). If the dwell time is set at ‘0’, this function is not available. Acc Dwell command is effective only first command input so it is not available in case the frequency passes by Acc Dwell frequency while resume the acceleration on stop. Dec Dwell operates when frequency passes by Dec Dwell frequency on stop command input and it is not operated on simple deceleration of frequency. Dwell operation is not operated when External brake control function is activated. A u t o - A A u t o - B S e q u e n c y 2 8-9
