Monitoring Operation During Adjustment - YASKAWA SGDV User Manual

6.1.3 Monitoring Operation during Adjustment

While adjusting the servo gain, always monitor the operating status of the machine and the signal waveform.
Connect a measurement instrument, such as a memory recorder, to the SERVOPACK to monitor the signal
waveform.
The settings and parameters that are related to monitoring the analog signal are described in the following sec-
tions.
(1) Connecting the Measurement Instrument
Use the external monitor connector (CN5) on the SERVOPACK to connect the measurement instrument. The
devices and cables that are required for connection are listed below.
• Analog monitor unit (model: JUSP-PC001-E)
• Analog monitor unit connection cable (model: JZSP-CF1S05-A3-E)
• Analog monitor cable (model: JZSP-CA01-E)
Connection examples are shown below.
