4.6 Operation by pulse input

Select one of the following three pulse input modes according to the equipment connected to the controller.
Note
Pulse input is implemented based on the negative logic.

4.7 A-phase pulse output, B-phase pulse output
●
C
●
D
A-phase pulse output (ASG) and B-phase pulse output (BSG) are available in two types: transistor
open-collector output and line-driver output.
Use either type to suit the input system of the counter unit and other functions of the controller.
Note
•
The pulse-output delays behind motorized actuator movement by up to 1 ms. The
output may be used to verify the stop position of the motorized actuator.
•
Use a frequency counter capable of counting frequencies up to at least twice the
frequency corresponding to the maximum speed used by your equipment.
•
When using the line driver output, connect a terminating resistance of 150
Ω
between
the line receiver inputs.
•
When using the open-collector output, use a cable that is 2 m (6.56 ft.) or shorter. With
the open-collector output, the output waveform changes depending on the load
conditions. Check the behavior depending on the devices used in combination.
