3. S1 (source 1): Control register
S1 specifies the first data register of the data registers to use with ZRN1, ZRN2, ZRN3 or ZRN4 instructions.
Starting from the specified data register, 14 consecutive data registers are used.
Specify the first data register so that the device range is not exceeded.
*1 The upper and lower data registers change according to the 32-bit data storage method specified. For details, see "32-bit Data Storage" on
page 3-9.
*2 When ZRN mode 0 is specified for the zero return method, starting number+6 to +10 are invalid.
*3 Valid only when Reversible control (single-pulse output) or Reversible control (dual-pulse output) is selected for reversible control enable.
4. S2 (source 2): Initialization Input
S2 specifies the initialization input. When the initialization input S2 is turned on, the initial values configured in the WindLDR ZRN (Zero
Return) dialog box, on the Settings tab, are stored in the control registers. An external input or an internal relay can be specified.
When the initialization input is on, the initial values are written to the data registers with each scan. (Even when the ZRN
instruction is not executed (when not on), if the initialization input is turned on, the initial values are stored in the data
registers.) To only initialize the values one time, use the initialization input in combination with the SOTU (single output up)
instruction or the SOTD (single output down) instruction.
5. S3 (source 3): Proximity Signal
S3 specifies the proximity signal. The pulse frequency starts being decreased with the rise in the proximity signal.
An external input or an internal relay can be specified for the proximity signal.
Notes:
• Do not use the same input or internal relay as the proximity signal for the ZRN1, ZRN2, ZRN3 and ZRN4 instructions. If they operate
simultaneously, pulse output may not stop even if the proximity signal changes from on to off.
• To use the high-speed proximity signal, set the relevant input to Normal Input under Special Input on Function Area Settings. Do not
use the input as interrupt input, catch input, high-speed counter, or frequency measurement.
• When using the high-speed proximity signal, ensure that no bounce occurs in the proximity signal.

Detection Speed Input Device Description
High-speed I0, I1, I3, I4, I6, I7
An interrupt is used to read the proximity signal. The proximity signal can be read without
being affected by the user program scan.
Normal
Inputs except I0, I1,
I3, I4, I6, and I7 and
Internal relays
The information updated in the END processing is read as the proximity signal. It is affected
by the user program scan.
