Monitoring Operation during Adjustment

Check the operating status of the machine and signal waveform when adjusting the servo gain. Connect a mea-
suring instrument, such as a memory recorder, to an analog monitor connector on the multi-winding drive unit
to monitor the analog signal waveform. The settings and parameters for monitoring analog signals are
described in the following sections.
