This extremely compact drive controller is the general-purpose solution for both, stepper motors and brushless DC motors. Magnetic field-orientated vector control and encoder feedback plus sine wave commutation ensure highly dynamic, very efficient, smooth and balanced operation at low running noise - particularly when it comes to driving stepper motors. Step errors are corrected along the path already and the load angle error is eliminated within a single full step. Owing to continuous motor current monitoring, the control unit supplies just as much power as necessary, thus making the system very energy-efficient. An integrated web server helps to set up the unit. Thus, no software needs to be installed to configure the module. Instead, any PC featuring and Ethernet port and a web browser will do. In order to reduce the certification efforts the module already has an UL-certification for the US and the Canadian market (cULus).
