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.

Connector P1 Configurations

Pin Function	Details
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 leftUNCONNECTED (ENABLED).

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:

Microstep	Steps/rev.(for 1.8o motor)	SW5	SW6	SW7	SW8
2	400	off	on	on	on
4	800	on	off	on	on
8	1600	off	off	on	on
16	3200	on	on	off	on
32	6400	off	on	off	on
64	12800	on	off	off	on
128	25600	off	off	off	on
5	1000	on	on	on	off
10	2000	off	on	on	off
20	4000	on	off	on	off
25	5000	off	off	on	off
40	8000	on	on	off	off
50	10000	off	on	off	off
100	20000	on	off	off	off
125	25000	off	off	off	off

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.

Peak Current	RMS Current	SW1	SW2	SW3
1.00A	0.71A	on	on	on
1.46A	1.04A	off	on	on
1.91A	1.36A	on	off	on
2.37A	1.69A	off	off	on
2.84A	2.03A	on	on	off
3.31A	2.36A	off	on	off
3.76A	2.69A	on	off	off
4.20A	3.00A	off	off	off

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