QD70)
(a) This signal notifies the QD70 that the PLC CPU is normal.
• It is turned ON/OFF with the sequence program.
• The PLC READY signal is turned ON during positioning
control, OPR control and JOG operation.
(b) When parameters and OPR data are changed, the PLC READY
signal is turned OFF.
(c) The following processes are carried out when the PLC READY
signal turns from OFF to ON.
• The parameter and OPR data setting range is checked.
• The module READY signal [X0] turns ON.
(d) The following processes are carried out when the PLC READY
signal turns from ON to OFF.
In these cases, the OFF time should be set to 100ms or more.
• The module READY signal [X0] turns OFF.
• The operating axis stops.
• OPR control and positioning control is started.
• The positioning start signal is valid at the rising edge, and the
operation is started.
• When the positioning start signal turns ON during BUSY, the
operation starting warning will occur (warning code: 10).
• When the axis stop signal turns ON, the OPR control, positioning
control and JOG operation. In these cases, the ON time should be
set to 4ms or more.
• Turning ON the axis stop signal during operation decelerates the
axis to a stop. At this time, " Md. 4 Axis operation status" changes
from "Deceleration (Axis Stop ON)" to "Stopped".
• When the JOG start signal is ON, JOG operation will be carried
out at the " JOG. 1 JOG speed". When the JOG start signal turns
OFF, the operation will decelerate and stop. At this time, " Md. 4
Axis operation status" changes from "Deceleration (JOG Start
OFF)" to "Standby".
• Set the rotation direction in " JOG. 4 JOG direction flag". (Refer to
Chapter 10.)
