6.1.3 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 connector CN5 analog monitor connector on the SERVO-
PACK to monitor analog signal waveform.
The settings and parameters for monitoring analog signals are described in the following sections.
(1) Connector CN5 for Analog Monitor
To monitor analog signals, connect a measuring instrument with cable (JZSP-CA01-E) to the connector CN5.
(2) Monitor Signal
The shaded parts in the following diagram indicate analog output signals that can be monitored.
∗1. The reference pulse input multiplication switching function is supported by software version 001A or later.
∗2. Available when the fully-closed loop control is being used.
Line Color Signal Name Factory Setting
