Introduction: With the adoption of its pioneer "pure sinusoidal current control technology" and the latest "self-adjustment technology", M series stepper drives can effectively reduce current ripples and mid-range vibration, enabling different motors to run at optimal performance and with lower heating. They can also eliminate drawbacks of difficulty of driving various motors, such as high heating with smaller inductance motors, low high-speed with large inductance motors, poor performance under low voltage, and high motor heating under high voltage.
Suitable for applications require high reliability, good high speed performance, extremely low cost stepper systems, such as routers, milling or engraving machines, textile equipment, assembly machines, pick-and-place devices, etc.

M542
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.

PUL+
Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each rising or falling edge active (set by inside jumper J1); 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. In double pulse mode (pulse/pulse) , this input represents clockwise (CW) pulse,active at high level or low level (set by inside jumper J1, J2). For reliable response, pulse width should be longer than 1.5µs. Series connect resistors for current-limiting when +12V or +24V used. The same as DIR and ENA signals.
PUL-
DIR+
DIR signal: In single-pulse mode, this signal has low/high voltage levels, representing two directions of motor rotation; in double-pulse mode (set by inside jumper J3), this signal is counter-clock (CCW) pulse,active at high level or low level (set by inside jumper J1, J2). For reliable motion response, DIR signal should be ahead of PUL signal by 5µs at least. 4-5V when DIR-HIGH, 0-0.5V when DIR-LOW. Please note that rotation direction is also related to motor-drive wiring match. Exchanging the connection of two wires for a coil to the drive will reverse motion direction.
DIR-
ENA+
Enable signal: This signal is used for enabling/disabling the drive. High level (NPN control signal, PNP and Differential control signals are on the contrary, namely Low level for enabling.) for enabling the drive and low level for disabling the drive. Usually left UNCONNECTED (ENABLED).
