•
Inputs A, /A:
Pulse input in encoder and counter mode of the terminal.
•
Inputs B, /B:
Phase-shifted pulse input in encoder mode of the terminal.
•
Counting direction input in counter mode of the terminal:
Counting direction:
◦ + 5 V (or open contact): up
◦ 0 V: down
•
Inputs C, /C:
Zero point pulse input for the terminal’s latch register.
This input is activated via the EN_LATC bit in the control byte of the terminal.
•
External Latch 24 V:
Additional latch input of the terminal.
This input is activated via the EN_LAT_EXT bit in the control byte of the terminal.
If this input is enabled, the counter value will be latched when the edge changes from 0 V to 24 V.
•
External Gate 24 V:
A high level at this contact suppresses counting by the terminal.
•
Status Input:
If the incremental encoder has an alarm output, it can be connected to the status input
(active low input with internal pull-up circuitry).
•
Ue:
Power supply for the encoder (+5 V).
•
Uo:
Power supply for the encoder (0 V).
•
0 V, 24 V:
A voltage supply of 0 V and 24 V must be connected to these contacts for operation of the
terminal.
