The ON/OFF timing and conditions of the input signals are shown below.
ON: READY • When the PLC READY signal [Y0] turns from OFF to ON, the parameter setting
range is checked. If no error is found, this signal turns ON.
OFF: Not READY/
Watch dog • When the PLC READY signal [Y0] turns OFF, this signal turns OFF.
timer error
• When watch dog timer error occurs, this signal turns OFF.
• This signal is used for interlock in a sequence program, etc.
OFF: Module
• After the programmable controller is turned ON or the CPU module is reset, this
access
signal turns ON if the access from the CPU module to the QD75 is possible.
disabled
• When "Asynchronous" is selected in the module synchronization setting of the CPU
ON: Module
module, this signal can be used as interlock for the access from a sequence program
access
to the QD75.
enabled
• In the WITH mode, this signal turns ON when the positioning data operation is
not set started. In the AFTER mode, this signal turns ON when the positioning data
operation is completed.
ON: M code is
set
• This signal turns OFF with the " Cd.7 M code OFF request".
• When M code is not designated (when " Da.10 M code" is "0"), this signal will
remain OFF.
• With using continuous path control for the positioning operation, the positioning will
continue even when this signal does not turn OFF. However, the warning "M CODE
ON SIGNAL START" (warning code: 503) will occur.
• When the PLC READY signal [Y0] turns OFF, the M code ON signal will also turn
OFF.
• If the operation is started while the M code is ON, the error "M CODE ON SIGNAL
START" (error code: 536) will occur.
OFF: No error • This signal turns ON when an error listed in Section 15.2 occurs, and turns OFF
ON: Error when the error is reset on " Cd.5 Axis error rest".
occurrence
OFF: Not BUSY • This signal turns ON at the start of positioning, OPR or JOG operation. It turns OFF
ON: BUSY
when the " Da.9 Dwell time" has passed after positioning stops. (This signal
remains ON during positioning.) This signal turns OFF when the positioning is
stopped with step operation.
• During manual pulse generator operation, this signal turns ON while the " Cd.21
Manual pulse generator enable flag" is ON.
• This signal turns OFF at error completion or positioning stop.
OFF: Start • This signal turns ON when the positioning start signal turns ON and the QD75 starts
incomplete the positioning process.
ON: Start (The start complete signal also turns ON during OPR control.)
complete
Positioning start signal [Y10]
Start complete signal [X10]
OFF: Positioning
• This signal turns ON for the time set in " Pr.40 Positioning complete signal output
incomplete
time" from the instant when the positioning control for each positioning data No. is
ON: Positioning
completed. For the interpolation control, the positioning completed signal of
complete
interpolation axis turns ON during the time set to the reference axis.
(It does not turn ON when " Pr.40 Positioning complete signal output time" is "0".)
• If positioning (including OPR), JOG/Inching operation, or manual pulse generator
operation is started while this signal is ON, the signal will turn OFF.
• This signal will not turn ON when speed control or positioning is canceled midway.
