CS-D403 Closed Loop Stepper Drive User Manual 1. Introduction Leadshine CS-D403 is a closed loop stepper drive designed to solve the loss of step problem in open loop stepper control systems, thus increase system reliability at minimal cost increase. It implements advanced control algorithm of Leadshine based on its tens of years’...

Use Leadshine ProTuner for CS-D software to configure this output as an IN POSITION output. In this case, an output signal can be sent out when the targeted position is in the “Target” range (see parameter Distance to Send "In position"...
3.1.2 Typical Control and Fault Output Connections The CS-D403 can accept differential and single-ended control signal inputs (open-collector and PNP output). A CS-D403 has 3 optically isolated control inputs, PUL, DIR, and ENA. Refer to the following two figures for connections of open-collector and PNP signals.
Power supply positive connection. 20-50VDC power supply voltage Power supply ground connection. Notes: see Appendix B for compatible Leadshine power supplies 3.5 Connector P5 – RS232 Connection The P5 connector in Figure 2 is a RS232 communication port for PC connection. Refer to the following pin definitions.
3.6 LED Light Indication There are two LED lights for CS-D403, one red and one green. The GREEN one is the power indicator which will be always on generally. The RED one is a protection indicator. It is off always when a CS-D403 operates normally, but will flash 1, 2 or 7 times in a 5-second period when error protection is enabled.
5.2 Power Supply Sharing Multiple CS-D403 drives can share one power supply to save space and reduce cost, if that power supply has enough power capacity. To avoid cross interference, connect each stepper drive directly to the shared power supply separately.

Leadshine Technology Co., Ltd. warrants its products against defects in materials and workmanship for a period of 12 months from shipment out of factory. During the warranty period, Leadshine will either, at its option, repair or replace products which proved to be defective.
CS-D403 Closed Loop Stepper Drive User Manual Appendix A. Leadshine CS-D508 Compatible Stepper Motors The following Leadshine stepper motors with 1000-line encoders have been tested working with the CS-D508 closed loop stepper drive. Frame Size Torque Length Model Series Notes (NEMA) (N.m / Oz-In)
CS-D403 Closed Loop Stepper Drive User Manual Appendix B. Leadshine CS-D403 Compatible Power Supplies It is highly suggested to use the following Leadshine power supplies to power CS-D403 to get optimized performance. Those power supply are specially designed for stepper and servo controls.
Confirm both encoder and power cables are connected properly and tightly secured. Power off the drive then swap the A+ and A- motor connections to the CS-D403 drive. The reason is the definitions of your Motor A+ and A- are different from those marked on CS-D403 motor connection pins (P3 of Figure 2).
