QD75M/
QD75MH
LD75 LD77
Positioning monitor
Enters the monitor mode from the positioning
data edit window and monitors the positioning
data during operation.
Block start monitor
Enters the monitor mode from the block start
data edit window and monitors the block start
data during operation.
Operation monitor
Monitors the operating states, such as feed
present values, axis feed speeds, axis statuses
and executed positioning data numbers, of all
axes.
History monitor
Monitors the error, warning, start history of all
axes.
Signal monitor
Monitors the X/Y devices, external signals or
status signals of all axes.
Operation monitor
