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. Different number of flashes indicates
different protection type (read Section 9).
4. Motor Selection
The CS-D403 is designed to power 2-phase (or 4-phase 0.9 degree) NEMA 11,14,17 stepper motors under 10000-line
incremental encoders (recommend 1000-line). Leadshine offers many high performance stepper motors compatible
with the CS-D403. The CS-D403 can also power similar stepper motors with incremental encoders from third-party
suppliers.
Notes
: Contact with Leadshine for NEMA8, NEAM11, NEMA14 stepper motors with 2000-line encoders.
5. Power Supply Selection
The CS-D403 can power small and medium size closed loop stepper motors (frame size from NEMA8 to 17) from
Leadshine 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,
while output current determines the output torque of the driven motor (particularly at lower speed). Higher supply
voltage will allow higher motor speed to be achieved, at the price of more noise and heating. If the motion speed
requirement is low, it’s better to use lower supply voltage to decrease noise, heating and improve reliability.

specially designed for stepper & servo controls.
