Description:
The EM542S is a versatile fully digital driver for high voltage, based on a DSP controller with state-of-the-art control software. It brings a unique level of smoothness to the system, providing optimum torque and zero mid-range instability. Motor self-test parameters and auto-setup technology provide easy handling and better customization depending on the use of different motors. The driven motor can be operated in quieter operation, with less heating, with smoother movement than most comparable controllers. It is suitable for 2-phase and 4-phase hybrid stepper motors. Its unique features make the EM542S an ideal solution for applications that require high performance.
Features:
• Anti-resonance for optimum torque, extra smooth movement, low motor heating and noise generation
• Supply voltage +20 to +50 VDC
• Eight settings for output current from 1.0 - 4.2 A via DIP switch, or 0.5 - 4.2 A via software (increase by 0.1 A)
• No-load current reduction to 50 % or 90 % selectable via SW4
• Auto-tuning for adaptation to a variety of NEMA 17, 23, 24 stepper motors
• Step and direction control (PUL/ DIR) or CW/ CCW (double pulse)
• Pulse input frequency up to 200 kHz (500 kHz optional)
• Configurable control command smoothing to reduce motor vibrations
• Microstep resolution: 16 setting 200 - 25,600 via DIP switch, or 200 - 51,200 via software (in steps of 200)
• Soft start without "jolt" when switching on
• Control signal inputs 5 V or 24 V optically decoupled
• Output signal for fault or brake
• Protection against overvoltage, overcurrent and contact faults in the motor wiring
Applications:
The EM542S stepper motor driver is designed to operate 2-phase or 4-phase NEMA 17, 23 and 24 hybrid stepper motors. It can be used in many industries (CNC machines, electronics, medical, automation, packaging...) for applications such as CNC routers, milling machines, plasma, laser cutters, factory assembly lines, vending machines, etc. With its excellent performance, simple design and easy set-up, the EM542S is ideal for many applications with step and direction Control.
