The optionally available Spetec stepper motor controller SM04 is an in-house development that can be fixed directly to the pump. It has been designed for the operation of 2-phase stepper motors with step angles of 1.8° and 0.9°. Using the Spetec SM04, a single full step can be subdivided into 64 microsteps. This corresponds to 12,800 steps per revolution. This ensures that the equipment runs extremely smoothly and silently.
Benefits
• On-chip temperature monitoring
• Reduced current at low speeds, resulting in less heating of stepper motor
• Simple control via analog input
• Quieter running through 1/64 microstep control
• Board can be operated without ventilation
• Compact assembly at installed pump
