3.5 LED Light Indication
There are two LED lights for CS-D808, 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-D808 operates normally, but
will flash 1, 2 or 7 times in a 5-second period when error protection is enabled. Different number of flashes indicates
different protection type (read Section 9).
4. Motor Selection
The CS-D808 is designed to power 2-phase (or 4-phase 0.9 degree) NEMA 34 stepper motors with 1000-line
incremental encoders. Leadshine offers many high performance stepper motors compatible with the CS-D808 which
you can find in the Appendix A of this document. The CS-D808 can also power similar stepper motors with 1000-line
incremental encoders from third-party suppliers.
5. Power Supply Selection
The CS-D808 can power medium size closed loop stepper motors (frame size NEMA 34) from Leadshine (see
Appendix A) or other motor manufacturers. To get good system performance, it is important to select proper supply
voltage and output current. Generally speaking, supply voltage determines the high speed performance of the motor,
