Technical features
PLD442 is an available microstepping stepper motor driver.
The device has inbuilt coil short-circuit protection, protection against
overvoltage and overheating. The driver works with standard control
protocol STEP/DIR/ENABLE. All driver’s control inputs are optoisolated
and logic levels 2.5V, 3.3V, 5V compatible.
The driver is AUTO-SLEEP mode supplied which is turned on when
there is no STEP signal.
The device is perfect for control of bipolar and unipolar Purelogic
R&D stepper motors (PL42/PL57 series) as well as other stepper
motors.
• Optoisolation of module control signals STEP/DIR/ENABLE.
• During STEP/DIR mode (MACH3, Linux, CNC via LPT or controller
PLCM USB/Ethernet).
• AUTO-SLEEP mode, driver after 1 sec standstill (lack of STEP signal)
automatically enters rotor hold mode (full/half operating current) for
heating reduction.
• Coil short-circuit module protection, over-voltage protection.
• Convenient dismountable clip connectors to step motor, power
source and control signals.
• Stepper motor driver PLD442 — 1 pcs.

Power off device before making any connections and mode operation
changing.
Do not mount the power switch after the power source (on the driver
power line).
Power switch should be installed before power supply, at ~220V side.
Do not connect the drivers in series, only ‘star’ connection is allowed.
Do not connect power supply’s «-» to ground, mass, housing, etc.
Strictly observe the polarity of power supply and control signals
connections. Radiator mounting (it is not included in the set) with a
minimum size of 100 cm
2
is required.
