Pulse Input
System
D There are four different types of pulse input systems:
1) Sign + pulse, 1X
2) A- and B-phase pulses, 1X
3) A- and B-phase pulses, 2X
4) A- and B-phase pulses, 4X
D Using the ladder program, set the initial setting of the pulse input method as the “pulse
input mode.”
Maximum
Count Speed
1) 1X: 200 Kpps
2) 2X: 400 Kpps
3) 4X: 800 Kpps
Count Width 1) Using the ladder program, set the initial setting of the pulse count range as the “count
width.”
2) The setting range is between 0 and 16,777,215 (decimal).
Pulse Input
Voltage
1) Use any of the following pulse input voltages: 3, 5, 12 and 24 VDC.
2) The connection methods of the encoder cable to field wiring terminals differ according
to the pulse input voltage.
Pulse Transfer
Circuit
1) Use any of the following pulse types: open collector output, TTL output, differential
voltage output.
2) For an open-collector output, external power (5/12/24 VDC, 10/20 mA) must be
supplied.
Internal
Control Signal
The following signals can be output to the High-speed Counter Module from the ladder
program.
1) Count enable:
The High-speed Counter Module can count pulses while this signal and the external
count enable signal are both ON.
2) Current position reset:
The current position of High-speed Counter Module can be reset by turning ON this
signal.
External
Control Signal
D The following signals can be input to the High-speed Counter Module from limit switches
or other external devices.
1) External count enable :
The High-speed Counter Module can count pulses while this signal and the count
enable signal are both ON.
2) External current position reset:
The current position of High-speed Counter Module can be reset by turning ON this
signal.
D Input circuit specifications: 12/24 VDC, photocoupler isolation, 2.5 mA/5 mA.
