JMC 2DM542 4.2A 2 Phase Digital Stepper Motor Driver

JMC 2DM542 4.2A 2-Phase Digital Stepper Motor DriverSpecifications:Type: 2-phase digital stepper motor driverMotor Compatibility: Suitable for 2-phase hybrid stepper motorsPower Supply: 24-50V DC (recommended to use switching power supply)Max Output Current: 4.2A peak, 3.0A RMS2. Power and Input Specifications:Power Input Voltage Range: 24V to 50V DCMax Output Voltage: 50V DCMin Input Voltage: 20V DC (for stable operation)Current Setting: Adjustable in 8 levels, ranges from 1.0A to 4.2AMicrostep Resolution: Configurable from full-step to 128 micro-steps3. Control Signals:Input Signal Types: Pulse (PUL), Direction (DIR), Enable (ENA)Pulse Input Frequency: 0-200 kHz (optocoupler isolated)Control Mode: Step and DirectionSignal Logic: Can accept both PNP and NPN signalsIsolation Voltage: 500V (pulse/direction enable signals)4. Motor Control Features:Microstepping Settings: 16 types of micro-step divisions (from full-step to 128 micro-steps)Self-Test Functionality: Self-test mode available for driver diagnosticAuto Half-Current Function: The driver automatically reduces current by half when the motor is at a standstill to reduce power consumption and heatingAnti-Resonance Feature: Smooths the motor operation in low-speed range, reducing noise and vibrationIdle Current Adjustment: Can be adjusted between 50%-100% of the rated current5. Protection Features:Overvoltage Protection: The driver will shut down if the input voltage exceeds the rated limit (50V DC).Undervoltage Protection: The driver will shut down if the input voltage is too low (below 20V DC).Overcurrent Protection: Protects against phase-to-phase short circuits or excessive motor current.Overheating Protection: Integrated over-temperature protection, shuts down if the internal temperature exceeds 70°C.Fault Output: LED indicator to signal fault status like overcurrent, overvoltage, and phase errors.6.
