DISPLAY AND WRITING IN THE

DATA

INPUT SCREEN* (Cent’d)

System number #6219 should be set at “O” except
for writing parameters.

. System number can also be set by the rotary

switch on the main printed circuit board.

For

details, refer to Maintenance Manual.

4.3.7

DISPLAYING AND WRITING PARAMETERS

In this system, various parameters are stored in the
memory and they determine operating conditions such as
tape code and feed rate. For details, see Appendix 2,
“LIST OF PARAMETER NUMBERS’. The parameters can

be displayed at any time even during automatic oper-
ation.

1. Kinds of parameters

Parameters are displayed either in decimal mode or
in binary mode.

Fig. 4.26 Parameters (in binary

mode) -Example

Parameter numbers

are assigned to

binary mode. Those of #6050 and up are assigned
to decimal mode.

Displaying parameters

Operation is the same as in displaying setting data
except that PRM should be depressed instead of SET.
See 4.3.6 “DISPLAY IN THE

Writing parameters

The parameter values are preset according
to the performance of the machine and pur-

poses.

T h e r e f o r e ,

you should consult the

machine tool builder if you want to change
parameter settings.

The parameter are protected with a system
No. switch provided on the top of control

unit main package so that they should not
be destroyed by wrong operation. Normally
system No, O is selected and, at this
time, the parameters cannot be rewritten

by any operation.

The operation of writing parameters is the same as

of writing setting data but the parameters are
protected. See 4.3.6 “DISPLAY IN THE
FUNCTION.

Parameters cannot be rewritten unless the
system No.

switch is set at “l. “

After rewriting parameters, be sure to re-
set the system No. switch at

If the following parameters have been

changed,

be sure to turn off power then turn it on
again

Otherwise the system might fail to

operate properly.
