DECS 50/5 1-Q-EC Amplifier, sensorlessmaxon motor controlControlling sensorless EC motorsThe actual rotor position is evaluated by using the Back-EMFsensing technique. Different start sequences with varying start-upprocedures can be easy selected.Operating modesDigital speed control with selectable regulation gain.FlexibleWide supply voltage range 10 - 50 VDC. Pluggable screw typeterminal block and a flexprint connector compatible with maxon flatmotors.Small designOpen and compact electronics board. Easy mounting with hexagonaldistance pins with inside thread.All-round functionalityDirection can be predetermined using a logic signal. The motor shaftcan be disabled or braked, as required. Speed can be monitoredthrough the speed monitor output. Different protective functionssafeguard the motor and amplifier. Status indicator with green andred LED.Flexible set value inputSet value input either by internal potentiometer or external analogvoltage. Different speed ranges can be selected using DIP switches.The DECS (Digital EC Controller Sensorless) is a 1-quadrant amplifier forthe control of sensorless EC motors with a maximum output of 250 watts.Technical data page 297Dimensions and connections page 300DEC 24/1 1-Q-EC Amplifier249630249631Operating modesDigital speed control or open loop speed control operation can beselected with a built-in jumper.FlexibleWide supply voltage range 5 - 24 VDC.
