Description
(a) This signal notifies the positioning module that the CPU module is normal.
• This signal is turned on and off with the program.
• This signal is turned on during the positioning control, OPR control, JOG
operation, inching operation, and manual pulse generator operation, unless
the system is in the GX Works3 test mode.
(b) When data (including parameter) has been changed, this signal is turned off
depending on the changed item.
(c) The following processing is performed when this signal is turned off and on.
• The parameter setting range is checked.
• Check that READY signal ([Md.140] Module status: b0) is on.
(d) The following processing is performed when this signal is turned on and off.
In this case, the OFF time should be set to 100 ms or more.
• Check that READY signal ([Md.140] Module status: b0) is off.
• The operating axis stops.
• M code ON signal ([Md.31] Status: b12) for each axis turns off, and 0 is stored
in [Md.25] Valid M code.
(e) When the module data backup or module data initialization is performed with
GX Works3 or the CPU module, turn off this signal.
• When Axis stop signal is turned on, the OPR control, positioning control, JOG
operation, inching operation, and manual pulse generator operation will stop.
• By turning on this signal during the positioning operation, the operation will be
stopped.
• Whether to decelerate or suddenly stop can be selected with [Pr.39] Stop
group 3 sudden stop selection.
• During the interpolation control of the positioning operation, if this signal of
any axis is turned on, all axes in the interpolation control will decelerate and
stop.
• When this signal is on, the JOG operation will be performed with [Cd.17] JOG
speed. When this signal is turned off, the operation will decelerate and stop.
• When an inching movement amount is set, the specified movement amount is
output for one control cycle and the operation stops.
• The OPR operation or positioning operation is started.
• Positioning start signal is valid at the rising edge, and the operation is started.
• When this signal is turned on during BUSY, Start during operation (Warning
code: 0900H) will occur.
• If this signal is on when Positioning start signal is turned on, the positioning
control does not start until this signal is turned off. (pulses not output) This
signal is used with Pre-reading start function.
