(17) Position data read command (PWRT)
Position data read complete (WEND)
These signals are used when the actuator is operated in PIO pattern 1 (teaching mode) as a
positioner operation axis in the command specification mode.
The PWRT signal is effective when the MODS signal is “1” (ON).
Turn the PWRT signal “1” (ON) and keep it in this condition for 20 msec or more (*1), and the current
position data will be written to the “Position” field under the position number currently specified by the
PLC. (*2)
The WEND signal turns “1” (ON) upon completion of writing.
On the host PLC side, the PWRT signal should be turned “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).
Turning the PWRT signal “0” (OFF) will turn the WEND signal “0” (OFF).
*1 Keep the signal “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 the position is undefined, the default value of the corresponding
parameter will be written.
(18) Forced brake release (BKRL)
The brake can be forcibly released by turning this signal “1” (ON).
