EM-101 DC-MOTOR CONTROLLER 24V 3A 4-QUAD FEATURES: • 4-quadrant • Protection with self recovering fuse • Settable current limit • Settable acceleration/brake ramp • Load compensation • Special braking options • Supply voltage compensation • Continuous / 2-step speed controlling • Positive driving logic • Mounting with DIN-rail or screws • High efficiency EM-101 is designed for modern automation systems. Controls can be performed easily with relay- or open collectoroutputs. Analog controls work with positive voltage. Usable motor can be permanent magnet motor with brushes in power range of 5 ... 70 W. Due to the advanced pulse control (PWM) the unit operates with high efficiency, low temperature losses and provides a high starting torque. Loading of the motor can be compensated with inbuilt RI-adjustment. The current, or in other words, the torque of the motor can be controlled with DIP-switch. The operation of the current limit is indicated with a red led. There are a variety of braking options available in this device. For most effective braking “reverse braking”-mode can be used. In this mode reversed driving is used for braking, which effects extremely fast function. Additionally the card utilises short circuit braking which short circuits the motor circuit during the braking. EM-101 also has inbuild settable time acceleration- and braking ramps.

EM-101 INSTRUCTIONS Supply voltage must be DC with ripple less than 20%. Supply voltage 20...34V ( 26...32V recommended ). In the beginning set all trimmers in the middle position. 1 2 3 4 - + + NOTE! When reversed braking is used the controller will take a very high current peak. Capacitor for the power supply should be at least 4700uF at 1A.
