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.
(1) Analog Monitor Connector Connections
