GRT1-CT1(-1) Counter Units
Section 7-4
The user can set the configuration tag to any value between 0 and 255. The
configuration tag is downloaded with the rest of the parameter settings to the
Counter Unit and uploaded with the rest of the parameter settings from the
Counter Unit.

Counter Input Mode
Select one of the following counter input modes.
Phase Differential Counting
The following figure illustrates the operation of phase differential counting.
Counter input mode
Description
Phase differential
×
1 Phase-shifted pulses are received on inputs A and B.
• When the pulses on input A lead the pulses on input B, the
counter value is incremented on the rising edge of input A.
• When the pulses on input B lead the pulses on input A, the
counter value is decremented on the falling edge of input A.
Phase differential
×
2 Phase-shifted pulses are received on inputs A and B.
• When the pulses on input A lead the pulses on input B, the
counter value is incremented on the rising and falling edges
of input A.
• When the pulses on input B lead the pulses on input A, the
counter value is decremented on the rising and falling edges
of input A.
Phase differential
×
4 Phase-shifted pulses are received on inputs A and B.
• When the pulses on input A lead the pulses on input B, the
counter value is incremented on the rising and falling edge of
both input A and input B.
• When the pulses on input B lead the pulses on input A, the
counter value is decremented on the rising and falling edge
of both input A and input B.
Pulse and direction
Input A pulses are counted and input B determines the direc-
tion of counting.
• While input B is ON, the counter value is incremented.
• While input B is OFF, the counter value is decremented.
• The counter value is changed on the rising edge of input A.
Up/down Counter
• The counter value is incremented when pulses are received
on input A.
• The counter value is decremented when pulses are
received on input B.
• The counter value is changed on the rising edge of input A or
B.
