1-1 Features and Functions
The CJ1W-CT021 High-speed Counter Unit is equipped with 2 Counters and counts over a maximum
binary range of 32-bits. Accepting input pulse frequencies of up to 500 kHz allows precise control of
fast motions. The Unit's bi-directional counting ability enables detecting movement in either direction.
Each Counter of the Unit can be configured independently. The Unit is equipped with 2 Digital Inputs, 2
Digital Outputs and 30 Soft Outputs. A maximum response time of 0.5 ms guarantees high-speed
closed loop control of applications.

Freely Configurable
You can make a flexible setting on this High-speed Counter Unit to suit the user application.
z
Counter Type
Configuring the Unit starts with choosing one out of 3 Counter Types:
• Simple Counter (refer to 3-2-1 Simple Counter)
• Circular Counter (refer to 3-2-2 Circular Counter)
• Linear Counter (refer to 3-2-3 Linear Counter)
By default all Counters are set to Simple Counter for which no configuration settings have to be
made, enabling every Counter to count pulses directly after the Unit has been powered up. For all
Counter Types the full counting range is available. Circular and Linear Counters can be configured
with Special Unit settings according to the application to control.
z
Input Signal Type
Depending on the type of input signal that your application requires, for every Counter a choice can
be made out of three input signal types:
• Phase Differential Inputs (multiplication by either 1, 2 or 4)
(refer to 3-3-1 Phase Differential)
• Up/Down Pulse Inputs (refer to 3-3-2 Up & Down Pulse)
• Pulse & Direction Inputs (refer to 3-3-3 Pulse & Direction)
