The Leadshine CS-D808 driver is a new generation stepper motor driver.
It operates in a closed loop and therefore provides real-time position feedback with 2-phase stepper motors equipped with encoders (NEMA size 34).
This solution combines the advantages of stepper motors and servomotors thanks to the management of encoders integrated into the motors.
The control interface is similar to that of a classic stepper motor driver. Since the encoder is managed directly by the driver, it can return an error signal to you in the event of a mechanical blockage (configurable tolerance window).
This solution therefore provides the positioning reliability of a servomotor but also great simplicity of implementation.

| 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 PC software). (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 | Pend+ | o | In-position Signal: OC output signal, active when the difference between the actual position and the command position is zero. This port can sink or source 20mA current at 24V. The resistance between Pend+ and Pend- is active at high impedance. |
| 8 | Pend- | o | |
| 9 | 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. |
