30 POSITIONING PARAMETER
30.2 Details of Parameters
OPR Dwell Time
Setting method: High Speed I/O Parameter, Special Device
Set the time until the completion flag for the DSZR/DDSZR instruction is turned on when OPR is completed. The setting range
for the OPR dwell time is 0 to 32767 ms. (Page 369 Dwell time)
■Special Device
Near-point Dog Signal
Specify the near-point dog signal to be used in OPR.
■Device No.
Setting method: High Speed I/O Parameter, Operand
The near-point dog signal does not occupy the input interrupt function, and its edge is detected with a 1-ms interrupt.
In CPU module for the same axis, the near-point dog signal can be set in the device to which the zero signal has already been
set. In high-speed pulse input/output module, it can be set overlapped to any input device (X) other than the zero signal.
■High Speed I/O Parameter
The input devices (X) available for CPU module are X0 to X17. The input devices available for high-speed pulse input/output
module are X0 to X377.
■Operand: Positioning Instruction
When the FX3 compatible operand is specified, DSZR/DDSZR instruction can set the near-point dog signal. The FX3
compatible operand specification is supported only in CPU module.
• The CPU module cannot be used when the assignment of another high-speed input function occupies 8 channels.
However, overlap of input numbers is allowed for input interrupts. (Page 556 Functions that share inputs and outputs)
• When specifying an input device (X) as an operand, use the device assigned in high speed I/O parameter.
■Logic
Setting method: High Speed I/O Parameter
Specify the logic of the near-point dog signal.
When [0: Positive Logic] is selected, the near-point dog signal functions on a rising edge.
When [1: Negative Logic] is selected, the near-point dog signal functions on a falling edge.
This logic setting is not applied to the near-point dog signal for devices other than input device (X) specified by the DSZR/
DDSZR instruction. The devices other than input device (X) functions on a rising edge.
