A-1-2 Incremental Encoder Input Units
The following table describes how to interpret the datasheets for Incremental Encoder Input Units.
A-1-2 Incremental Encoder Input Units
Interpreting Datasheets
Unit name The name of the Unit. Model The model of the Unit.
Number of channels
The encoder input capacity of
the Unit.
Type of external
connections
The type of wiring for the Unit, i.e., termi-
nal block or connector. For a screwless
clamping terminal block, the number of
terminals on the terminal block is also
given.
I/O refreshing method
The I/O refreshing method of the Unit. The following refreshing methods are supported:
Free-Run refreshing, synchronous I/O refreshing, and task period prioritized refreshing.
Indicators
The indicators on the Units and
their layout.
Input signals
The input signals.
Input form The form of encoder input.
Counting unit The unit of counting
Pulse input method The usable pulse input method.
Counter range The usable counting range. You can also set minimum and maximum values.
Counter functions The usable counter functions.
Voltage input specifications: These are the encoder input specifications for models with voltage inputs.
Input voltage
The rated input voltage and
voltage range. ON voltage
The input voltage at which the input
turns ON and the input current at that
time.
Input current
The input current at the rated
voltage. OFF voltage
The input voltage at which the input
turns OFF and the input current at that
time.
Maximum response
frequency
The maximum frequency of the encoder input.
Internal I/O com-
mon processing
The polarity of the connected input device. There are models with NPN and PNP connections.
Line driver specifications: These are the encoder input specifications for models with a line receiver input.
Input voltage
The rated input voltage and
voltage range.
High level input
voltage
The high level input voltage.
Input impedance
The input impedance.
Low level input
voltage
The low level input voltage.
Hysteresis voltage The hysteresis voltage.
Maximum response
frequency
The maximum frequency of the encoder input.
5-V power supply
for encoder
The output voltage and output current of the 5-V power supply for the encoder.
External input specifications: These are the input specifications for the external inputs.
Input voltage
The rated input voltage and
voltage range.
ON voltage/ON
current
The input voltage at which the input
turns ON and the input current at that
time.
Input current
The input current at the rated
voltage.
OFF voltage/OFF
current
The input voltage at which the input
turns OFF and the input current at that
time.
ON/OFF response
time
The delay time in a change in the state of an input terminal reaching the internal circuit. The ON
delay time is given first followed by the OFF delay time.
Internal I/O com-
mon processing
The polarity of the connected input device. There are models with NPN and PNP connections.
