Leadshine's EM556S driver is a new generation digital stepper motor
controller. It ensures smooth movements at low speed, optimum torque,
low heating and low operating noise.
Its excellent performance, simple design and ease of configuration make
the EM556S an ideal tool for many applications such as pitch and
direction control (CNC machining, 3D printing, etc...).
-
Features: This driver allows operation in microsteps allowing high
resolutions to be reached up to 25600 steps per revolution (and even up
to 51200 steps per revolution via the EM-S ProTuner application).
The switches SW11 to SW16 allow the adjustment or activation / deactivation of the various functionalities.
It is suitable for bipolar or unipolar 6-wire motors (half coil or full coil) of the NEMA 23, 24 and 34 series.
-
Interfaces: The input voltage level on the pulse/direction inputs is
directly adjustable via switches, which dispenses with the addition of
resistors in the case of 24V signals.
The connectors are detachable but should not be removed or reattached when the power supply is connected due to back EMF which can damage the driver.
An RS232 interface allowing driver configuration is available for advanced users. This configuration is carried out via the EM-S ProTuner application available for free download.
The RS232 interface is accessible on a 4-pin connector using the DMD Mini configuration cable DMD Mini (not included). This DB9 output cable requires a convertisseur USB/RS232.
- Power supply: The choice of power supply is essential. If the
application requires low speed, it is preferable to use a supply voltage
close to the minimum possible, which reduces noise and heating and
increases torque.
A high supply voltage will give a high speed but at the cost of more noise, heating and possible vibrations at low speed.
Features:

- Current setting:
- via dip-switches: 1,8 A - 2,1 A - 2,7 A - 3,2 A - 3,8 A - 4,3 A - 4,9 A - 5,6 A
- via app (cord required not included): from 0.5 to 5.6 A (resolution: 0.1 A) - Micro-step Mode:
- via dip-switches: 200 à 25600 pas/tour
- via application (cord required not included): 200 to 51200 steps/turn (resolution: 200 steps) - Logic intensity: 7 to 16 mA
- Functions:
- anti-resonance system providing optimum torque
- multi-stepping mode
- configurable resolution in multi-step mode
- automatic reduction in no-load consumption
- suitable for unipolar and bipolar motors
