14.2.14 Analog monitor
Each of the Servo drives and Spindle drives has an analog monitor function. You can
observe various waveforms using a measuring instrument, such as an oscilloscope, con-
nected to a monitor cable from the CN16 (CN26 in the case of 2nd axis of the 2-axis-com-
bined drive) of each unit.
Servo drive
• MD3003 (Pn003) FUNCTION_SWITCH_APPLIC3 (For each axis)
Meaning: Function selection application switch 3
Initial value: 0002 (Monitor 1: Motor rotation speed; monitor 2: torque reference)
The following table shows a list of data that can be observed at a Servo drive and explains
how to set the magnification and others.
