Typical Connection; Digital Input Connection - StepperOnline CL57T User Manual

6. Typical Connection

A complete closed loop stepper system should include a stepper motor with encoder, CL57T(V4.0) drive, power
supply and controller (pulse generator). A typical connection is as below.
Notes: (1) Pulse and direction inputs level 5V or 24V selected by selector switch S3. When it is 24 V, the S3 selection
of 5V will damage the input photo-coupling.
(3) Enable (ENA) signal is 5V~24V compatible.

6.1 Digital Input Connection

The CL57T(V4.0) can accept can accept differential or single-ended control signals (pulse, direction, and enable) in
open-collector or PNP connection through the P1 connector (figure 2). It is recommend to add an EMI line filter
between the power supply and the drive to increase noise immunity for the drive in interference environments.

Notes:
(1) ENA signal is no-connected as default;
(2) Control signal amplitude is 24 V as default. If it is 12 V, please set the S3 (Figure 2) selector switch to 5 V first, then
connect 1KΩ resistor; If it is 5V, please set the S3 to 5V.
