Precautions for input signal assignment
• Do not setup to a value other than that specified in the table.
• The same signal can’t be assigned to multiple pins. Otherwise, duplicated assignment will cause Err 33.0 “Input
multiple assignment error 1 protection” or Err 33.1 “Input multiple assignment error 2 protection”.
• A signal used in multiple control modes should be assigned to the same pin and the logic should be matched. If not
assigned to the same pin, the Err33.0 “Input duplicate assignment error 1 protection” or Err33.1 “Input duplicate
assignment error 2 protection” occurs. In case that the logics do not match, Err33.2 “Input function number error 1
protection” or Err33.3 “Input function number error 2 protection” will occur.
• The duplicated assignment of SI-MON1 and EXT1, SI-MON2 and EXT2, SI-MON4 and EX-SON, and SI-MON5
and E-STOP is not allowed. Duplicate assignment will cause Err33.0 “Input duplicate assignment error 1
protection” or Err33.1 “Input duplicate assignment error 2 protection”.
• A-CLR can only be set at a-connect. If set at b-connect, then Err33.2 “Input function number assignment error 1
protection” or Err33.3 “Input function number assignment error 2 protection” will occur.
• EXT1 can be allocated only to SI5, EXT2 only to SI6. Wrong allocation will cause
Err 33.8 “Latch input allocation error protection”.
• The Err33.8 “Latch input allocation error protection” occurs if HOME is assigned to S16 and S17, POT is assigned
to S15 and S17, and NOT is assigned to S15 and S16.
• When latch correction pins (SI5/SI6/SI7) are used, set up is required for all the control modes. If configuration is
made only for 1 or 2 modes, the Err33.8 “Latch input allocation error protection” occurs.
• When latch correction pins (SI5/SI6/SI7) are used, only a-contact can be specified. If b-contact is specified, the
Err33.8 “Latch input allocation error protection” occurs.
If a latch correction pin is assigned to the over-travel inhibit input (POT/NOT), a-contact is specified. So, the
over-travel inhibit input does not work when cable is broken. Be sure to secure safety using another method (e.g.
installing a mechanical stopper).
Safety precautions:
The over-travel inhibit input (POT, NOT) and forced alarm input (E-STO
P) should normally be set to
b-contact, which stops when wire is broken.
If a-contact is specified, be sure that there is no safety hazard.
