Built-in Inputs Section 6-1
Conditions for Incrementing/Decrementing the Count
• The count is incremented when the direction signal is ON and decre-
mented when it is OFF.
• Only up-differentiated pulses (rising edges) can be counted.
Up/Down Mode The up/down mode uses two signals, an increment pulse input and a decre-
ment pulse input.
Conditions for Incrementing/Decrementing the Count
• The count is incremented for each increment pulse input and decre-
mented when for each decrement pulse input.
• Only up-differentiated pulses (rising edges) can be counted.
Increment Mode The increment mode counts single-phase pulse signal inputs. This mode only
increments the count.
