CL42T(V4.1) Closed-Loop Stepper Driver
4
Notes: (1) Shielding control signal wires is suggested;
(2)
To avoid/reduce interference, don’t tie control signal cables and power wires together;
(3) Brake output need to connect a relay and diode

P5 – Debug Port
The P5 connector in Figure 2 is a RS232 communication port for PC connection. Refer to the following pin
definitions.CL42T has a tuning port with RS232 to modify the drive parameters; it is just used to modify
parameter, not for equipment control because neither precision nor stability is sufficient.
The interface definition is as follows:
