Driver for Leadshine DM442

Description

DM442 is a digital stepper motor driver based on a signal processor using modern control algorithms. It implements high smoothness of the stepper motor shaft, high output torque and stepper motor resonance compensation algorithms.

• Resonance suppression system and automatic adjustment function of the driver to the motor to obtain optimal motion parameters
• Step division up to 1:512
• Built-in configurations for 16 types of motors
• STEP/protocol support DIR
• TTL compatible optoisolated inputs
• Automatic holding current reduction (adjustable reduction rate)
• Protection against supply overvoltage, phase overcurrent, motor phase misconnection

DM442 is designed for 2-phase and 4-phase motors (14-34 Nema)

Options

The driver uses an 8-bit DIP switch to set the microstep resolution and motor operating current:

&nbsp; SW 1 ┐ &nbsp; &nbsp; SW 2 ├─ Operating current &nbsp; SW 3 ┘ &nbsp; &nbsp; SW 4 ── Holding current (50%/100%) &nbsp; SW 5 ┐ &nbsp; &nbsp; SW 6 │ &nbsp; &nbsp; SW 7 ├─ Microstep resolution &nbsp; SW 8 ┘ &nbsp;

Setting the operating current, the first three DIP switches (SW1, 2, 3):

Peak current, A RMS current, A SW1 SW2 SW3 Default setting / software (from 0.5 to 4 .2 A) on on on 1.46 1.04 off on on 1.91 1.36 on off on 2.37 1.69 off off on 2.84 2.03 on on off 3.31 2.36 off on off 3.76 2.69 on off off 4.20 3.00 off off off

Setting the holding current with switch SW4.
In the OFF position, the holding current is set to 50% of the operating value,
in the ON position, it is set equal to the selected value of the operating current.

Microstep mode selection

is set by DIP switches SW5, 6, 7, 8 as shown in the table:
