Chapter 13 Control Sub Functions
(5) During simultaneous start, a stroke limit check is carried out for the current
values of every axis to be started. Every axis will not start if an error occurs,
even if it only occurs in one axis.
[5] Setting the software stroke limit function
To use the "software stroke limit function", set the required values in the
parameters shown in the following table, and write them to the Simple Motion
module.
The set details are validated at the rising edge (OFF
ON) of the PLC READY
signal [Y0].

Refer to Section 5.2 "List of parameters" for setting details.
[6] Invalidating the software stroke limit
To invalidate the software stroke limit, set the following parameters as shown,
and write them to the Simple Motion module. (Set the value within the setting
range.)

(To invalidate only the manual operation, set "1: software stroke limit invalid" in
the "

The set details are validated at the rising edge (OFF
ON) of the PLC READY
signal [Y0].
When the unit is "degree", the software stroke limit check is not performed during
speed control (including speed control in speed-position switching control or
position-speed switching control) or during manual control, independently of the
values set in
Pr.12
,
Pr.13
and
Pr.15
.
REMARK
Parameters are set for each axis.
It is recommended that the parameters be set whenever possible with GX Works2.
Execution by sequence program uses many sequence programs and devices. The
execution becomes complicated, and the scan times will increase.
