Description
24V power supply for switches etc. maximum load 200 mA
24V power supply for switches etc. maximum load 200 mA
Reference position index number bit 0 (least significant bit).
Not used in field bus mode.
Reference position index number bit 1.
Not used in field bus mode.
Reference position index number bit 2.
Not used in field bus mode.
Reference position index number bit 3.
Not used in field bus mode.
Ground for 24V is normally bridged with Terminal 39, but can be
set to "OFF" by means of Switch SW 4 on the control card.
Errors are cleared on the rising edge (must be "0" min. 1 ms. to
guarantee edge detection). Not used in field bus mode.
To enable operation, this input must be maintained at "1" in
either digital control mode or field bus control mode.
Reference position index number bit 4 (most significant bit).
Not used in field bus mode.
While this input is high the drive executes the homing sequence.
While this input is high no position or jog operations are carried
out. Any homing sequence is interrupted by a low state on this
input.
Not used in field bus mode.
Active on the rising edge (must be "0" min. 1 ms. to guarantee
edge detection):
Latches reference position index number specified on terminal
16, 17, 18, 19, 29 into memory. Digital output MK3C 4 – 8 is
changed to mirror the new reference index specified when using
digital input control.
Not used in field bus mode.
