VFD-F Series

5-92

Pr11-01=02 Fixed Amount Circulation

When Motor#1 of the inverter accelerate from 0Hz to the highest frequency, it will follow

Pr11-05<Motor switch delay time during Fixed Amount Circulation> to decelerate. After the time set by

Pr11-04<Motor Switch Delay Time>, Motor01 will not be powered by the inverter but by the mains.

Then after the same length of time set by Pr11-04<Motor Switch Delay Time>, Motor#2 will be powered

by the inverter, so on and so forth. Please refer to the Increasing Demand graph.

When Motor#4 which is powered by the inverter decreases from the largest frequency to 0Hz and after it

runs for the length of time set by Pr11-16, it will make one of the motor not to be powered by the mains

electricity. Then after it runs again for the same length of time set by Pr11-16, it will stop another motor

being powered by the mains electricity, so on and so forth. Please refer to the Decreasing demand graph.

No matter it is the acceleration or the deceleration, the 4 motors will be running at this order repeatedly:

1-2-3-4-1-2-3-4

 Setting of Related Parameters

Pr11-01=02 Select <Fixed Amount Circulation>.

Pr11-02=X Set quantity of motors, maximum 4.

Pr11-05=X Set motor switch delay time

Pr11-06=X Activation Frequency of an Auxiliary

Pr11-04=X Command from the AC drive to increase the motor switch delay time (Please refer to

Increasing demand graph)

Pr11-14=X Command from the AC drive to decrease the motor switch delay time (Please refer to

the Decreasing demand graph).

Multi-function output terminal will follow Pr11-02 for setting.
