4.7 A-phase pulse output, B-phase pulse output
(common to the controller and driver modes)
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 according to the resistance and
stray capacitance of the cable as well as other factors. Check the behavior depending
on the devices used in combination.
