SETTING THE OUTPUT CURRENT
The output circuit (drive 8) is structured as illustrated below (in the output circuit diagram). As found in “Output
Current Waveform” below, the source current value of the output current waveform has a constant current setting.
Note that the source current is set by the following equation:
