B15 Outputs Pulses and pulse symbols for positioning the drive module corresponding
to the transistor outputs.

B1 • Inputs from the limits switch at the stroke upper limit position.
• Positioning stops when this signal is turned OFF.
• This is the upper limit that searches for near-point dog signals when the OPR
retry function is enabled.
B2 • Inputs from the limits switch at the stroke lower limit position.
• Positioning stops when the lower limit signal is turned OFF.
• This is the lower limit that searches for near-point dog signals when the OPR
retry function is enabled.
B3 • Used to detect near-point dog during mechanical OPR.
• Detects near-point dog signals using OFF→ON.
B4 • Inputs when positioning is canceled.
• The positioning module cancels positioning when this signal is turned ON.
Subsequently, the device does not move even if this signal is turned from ON to
OFF.
B5 • Inputs control switching signals using speed-position switching control and
position-speed switching control.
• Used as input signals for external positioning start, speed change requests, and
skip requests. Use "[Pr.42] External command functions selection" to set which
functions can use this signal.
B6 Common for upper/lower limit signals, near-point dog signals, stop signals, and
external command signals.
B7
B11 • Turns ON when the feed pulse can be received at the drive unit is normal.
• The positioning module checks the drive module READY signal, and if the
status is not ready, outputs an OPR request.
• This signal turns OFF when the drive module operations status is defective,
such as if an error has been output to the drive module control power supply.
• Stops if this signal is turned OFF during positioning. Does not start even if the
signal is turned ON again.
• The OPR complete signal also turns OFF if this signal is turned OFF.
B12 • The drive unit READY common.
B13 Output during machine OPR. (Not output, however, if using count method 2.)
(E.g.) If using machine OPR with stopper stop method 2.
Speed
CLEAR
• Set the deviation counter clear output time using "[Pr.55] Deviation counter clear
signal output time".
• When the positioning module turns ON this signal, the drive module can reset
the stop pulse amount of the internal deviation counter.
Note: Deviation counter clear is the signal output by the positioning module during
mechanical OPR. The user cannot specify the outputs.
B14 The deviation counter clear common.
