Leadshine CS-D508 is a closed loop stepper drive. When used to drive a 2-phase stepper motor in frame sizes NEMA 17, 23, 24, or 34 with incremental <span">rotary encoder, it can close the position loop between the motor and drive and therefore eliminate the loss of step problem in an open loop system. The CS-D808 adopts Leadshine advanced control algorithm. It is very easy to configure and setup. It It is ideal for upgrading open loop stepper systems, or replacing servo systems in some low to middle speed applications.
Compared with an open loop stepper system, a CS-D808 adopted closed loop stepper system can eliminate loss of step, make real-time position error correction, and use 100% available torque of the driven stepper motor. It can also power the driven stepper motor with reduced heating, lower noise, low vibration, …
When compared with a servo system, a CS-D808 adopted closed loop stepper system can have much higher low-to-middle-speed torque. such a control system also has the advantages of no tuning, no hunting, no overshooting, and much lower cost.

|---|---|---|---|
| Pin | Name | I/O | Description |
| 1 | PUL+ | I | Pulse signal: (1). In single pulse (pulse & direction) control mode, this input represents pulse signal. A pulse signal is active at the rising or falling voltage edge (set by switch SW7). (2). In double-pulse (CW/CCW) control mode (set by PC software), this signal input represents clockwise (CW) pulse, and is active at both high voltage level and low voltage level. (3). 4.5-24V for voltage HIGH, 0-0.5V for voltage LOW (same for DIR and ENA signals). (4). Pulse width should be set to 2.5μs or longer. |
| 2 | PUL- | I | |
| 3 | DIR+ | I | Direction Signal:(1). In single pulse (step & direction) control mode, this signal’s low and high voltage levels represent the two directions of motor rotation (e.g. clockwise and counterclockwise). (2). In double-pulse (CW & CCW) control mode, this signal represents counterclockwise (CCW) rotation. It is active at both voltage high level and low level. (3). Minimal DIR signal setup time should be at least 5μs. (4). Rotation direction is related to your motor/drive wiring. You can reverse the default rotation direction by toggling the SW5 DIP switch.. |
| 4 | DIR- | I | |
| 5 | ENA+ | I | Enable signal: This signal is used for enabling/disabling the drive. High voltage level of 4.5-24V (NPN control signal) for enabling the drive and low voltage level of 0-0.5VDC for disabling the drive. PNP and Differential control signals are on the contrary, namely Low level for enabling. By default this signal is left UNCONNECTED & ENABLED. |
| 6 | ENA- | I | |
| 7 | ALM+ | O | Fault Signal: An OC output signal which is active when one of the following error protection is activated: over-voltage, over-current, and position following error. This port can sink or source 20mA current at 24V. The resistance between ALM+ and ALM- is low impedance in normal operation, and will change to high when the drive goes into error protection. The voltage active level of this false output signal can be configured by configuration software. |
