11 - 01 Start-up Frequency of the Auxiliary Motor

Settings

0.00 to 400.00 Hz

Unit: 0.01

Factory Setting: 0.00

This parameter serves as a reference for the startup value of the auxiliary motor. If the setting

is 0, the auxiliary motor cannot be activated.

11 - 02 Stop Frequency of the Auxiliary Motor

Settings

0.00 to 400.00 Hz

Unit: 0.01

Factory Setting: 0.00

When the output frequency reaches this parameter value, the auxiliary motor will be stopped.

There must be a minimum of 5 Hz difference between the start frequency and stop frequency

of auxiliary motor. (Pr.11-01-Pr.11-02) > 5 Hz.

11 - 03 Time Delay before Starting the Auxiliary Motor

Settings

0.0 to 3600.0 sec

Unit: 0.1

Factory Setting: 0.0
