leadshine M542 stepper drive, High performance, cost-effective, Supply voltage up to +50 VDC, Output current up to 4.2A - details see: https://www.machineto.com/leadshine-m542-stepper-drive-for-step-motor-57hs22-57hs13-57hs09-10234563

Shanghai Sun-Up Laser Technology Co.,Ltd. Promise:

Many customer told us that they are afraid to buy the Copy products, we promise all the product sold by SP Laser is original, not only because we are one of the most famous and largest manufacturer of Co2 laser tubes in China, we also focus more on our brand and all of our products is original and famous, we have long history and will aways provide high quality products, for this point

1)you can ask more other suppliers or make a search on us if you have any doubts.

2) Although we are not the manufacturer of leadshine, but our worker can repair and install the laser machines by themselves and we also do trading on laser machine, we are more professional than some companies.

Introduction:

The M542 V2.0 is a high performance microstepping drive based on pure-sinusoidal current control technology. Owing to the above technology and the self-adjustment technology (self-adjust current control parameters) according to different motors, the driven motors can run with smaller noise, lower heating, smoother movement and have better performances at higher speed than most of the drives in the markets. It is suitable for driving 2-phase and 4-phase hybrid stepping motors.

Selecting Microstep Resolution and drive Output Current

This drive uses an 8-bit DIP switch to set microstep resolution, and motor operating current, as shown below:

Microstep Resolution Selection

Microstep resolution is set by SW5, 6, 7, 8 of the DIP switch as shown in the following table:

Current Settings

The first three bits (SW1, 2, 3) of the DIP switch are used to set the dynamic current. Select a setting closest to your motor's required current.

Note: Due to motor inductance, the actual current in the coil may be smaller than the dynamic current setting, particularly under high speed condition.
