(17) Position data read command (PWRT) PLC output signal
Position data read complete (WEND) PLC input signal
These signals are used when a positioner operation axis is operated in the command specification
mode under PIO pattern 1 (teaching mode).
The PWRT signal is effective when the MODS signal is “1” (ON).
When the PWRT signal is turned “1” (ON) for 20 msec or more (*1), the current position data will be
written to the “Position” field under the position number currently specified by the PLC command. (*2)
When the writing is complete, the WEND signal turns “1” (ON).
The host PLC should turn the PWRT signal “0” (OFF) after the WEND signal has turned “1” (ON).
If the PWRT signal is turned “0” (OFF) before the WEND signal turns “1” (ON), the WEND signal will
not turn “1” (ON).
When the PWRT signal is turned “0” (OFF), the WEND signal turns “0” (OFF).
*1 Make sure the signal remains “1” (ON) for 20 msec or more. If the signal is turned “1” (ON) for
less than 20 msec, the data may not be written.
*2 If any data other than position is not yet defined, the default value of the applicable parameter
will be written.
(18) Forced brake release (BKRL) PLC output signal
You can forcibly release the brake by turning this signal “1” (ON).
20 msec or more
