Commissioning procedure:
1. Connect the HDO terminal to the eddy current control module according to Figure 5-14
Connecting the HDO terminal to the eddy current control module.
2. Set P91.37=1 to enable eddy current control for tower crane slewing, and set P91.48 to adjust
HDO carrier frequency.
3. Set P91.38–P91.47 to adjust the eddy current control module output voltage change with
frequency.
Note: The duty ratio that is output when bit1 of P06.05 is 1 decreases when the frequency
increases. The eddy current control module output voltage decreases when the frequency
increases.
