1. Outline and purpose
There are the following simulation functions to check the machine
operations, troubleshoot, find causes, make various settings,
improves adjustment work speeds and serviceability.

1) Various adjustments
2) Specification and function setting
3) Trouble cancel
4) Operation check
5) Counters check, setting, clear
6) Machine operation conditions (operation history) data check, clear
7) Transmission of various data (adjustment, setting, operations,
counter, etc.)
The operating procedures and displays slightly differ from the form of
the machine operation panel.
the machine operation panel.
The typical forms are as follows:
1) Code system: Values input and mode selection are made with the
10-key pad and various function keys.
2) Switch system: Simulation mode selection is made by combination
of switch setting.
3) Values and mode selection is made with various function keys. As
a special one, a jumper wire is used to connect the check points
on the PWB to select the desired mode.
