Description
Off: PLC READY OFF (a) This signal notifies the RD75 that the CPU module is normal.
On: PLC READY ON • 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 test mode of the engineering tool.
(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.
• RD75 READY signal [X0] turns 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 100ms or more.
• RD75 READY signal [X0] turns off.
• The operating axis stops.
• M code ON signal [X4, X5, X6, X7] 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
an engineering tool or the CPU module, turn off this signal.
Off: No axis stop request • When Axis stop signal is turned on, the OPR control, positioning control, JOG
On: Axis stop request 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.
Off: JOG not started • When this signal is on, the JOG operation will be performed with [Cd.17] JOG
On: JOG started 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.
Off: No positioning start • The OPR operation or positioning operation is started.
request • Positioning start signal is valid at the rising edge, and the operation is started.
On: Positioning start • When this signal is turned on during BUSY, Start during operation (Warning
request code: 0900H) will occur.
Off: Not during execution • If this signal is on when Positioning start signal is turned on, the positioning
prohibition control does not start until this signal is turned off. (Pulse output is not
On: During execution performed.) This signal is used with Pre-reading start function.
