Trouble diagnosis monitor screen

Outline

Trouble diagnosis monitor screen displays information when the alarm is occurred necessary to diagnose
the servo/spindle alarm.

Servo/spindle monitor data on "1-4 immediately before occurrence of the alarm" for four samplings
immediately before and "The latest alarm is occurred" can be displayed as data when the alarm is
occurred.
Moreover, "Present" of servo/spindle monitor data when usually operating can be displayed.

Display procedure of trouble diagnosis monitor screen (for 8.4/10.4-inch display
unit)

Procedure

Press function key

Press the continuous menu key

until soft key [MONIT] appears.

Press soft key [MONIT].

The following screen is sample of displaying data of X axis (servo) when the alarm occurred.

Fig.18.4.4 (a) Trouble diagnosis monitor screen (10.4-inch display unit)

The servo monitor data screen and the spindle monitor data screen can be switched by pushing soft
key [MON_SP] / [MON_SV].

Display procedure of trouble diagnosis monitor screen (for 15/19-inch display unit)

Procedure
