<strong>EM</strong>-<strong>101</strong>-<strong>BI</strong> <strong>MOTOR</strong> <strong>CONTROLLER</strong> <strong>24V</strong> <strong>4A</strong> 4-<strong>QUAD</strong>FEATURES- 4 Quadrants- Self recovery fuse- Adjustable current limit- Adjustable accel./braking ramp- Load compensation- Special braking options- Supply voltage compensation- Speed control ±10V ( ±5V )- Positive control logic- Mounting with DIN-rail or screws- High efficiency<strong>EM</strong>-<strong>101</strong>-<strong>BI</strong> is designed for modern automation systems. Controls can be performed easily with relay- or open collectoroutputs. Analog controls work with ±10V voltage. Usable motor can be permanent magnet motor with brushesin power range of 5...80 W. Due to the advanced pulse control (PWM) the unit operates with high efficiency, lowtemperature 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 torqueof 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”-modecan be used. In this mode reversed driving is used for braking, which effects extremely fast function. Additionallythe card utilises short circuit braking which short circuits the motor circuit during the braking.<strong>EM</strong>-<strong>101</strong> also has inbuild settable time acceleration- and braking ramps.TECHNICAL DATASupplyOver volt. protect.Idle currentControl currentControl powerMotor voltageCurrent limitVoltage lossFuseRampControl voltageControl pot.Digital cont.DimensionsWeight12-34Vdc36Vapprox. 50mA<strong>4A</strong> continuous, 5A max.80W continuous0-15V ( 12V range )0-29V ( <strong>24V</strong> range )0.3...5A1V when Im=<strong>4A</strong><strong>4A</strong> self recovery.0,5s...5s-5...0...5V -->-10...0...10V2...10kohm"on" when Uin 4 -30V"off" when Uin 0-1V or open89x73x26mmapprox. 70g957865V 5mACONTROL GND-5V 5mASPEED SETSPEED SCALERUN/STOPRAMP.I-LIM.REVERSEBRAKE TIME<strong>EM</strong>-<strong>101</strong>-<strong>BI</strong> BLOCK DIAGRAMCONTROL VOLTAGE-5VCONTROLLOGICPOWERREGUL.POWER STAGEH-BRIDGE12V / <strong>24V</strong>VOLTAG<strong>EM</strong>EAS.CURRENTMEAS.<strong>4A</strong> PTC FUSE+-1SUPPLYIN23-<strong>MOTOR</strong>+4IR-KOMP.

COMPENSATIONWith compensation you can compensate the loadeffect to motor rpm. This feature increases controllingif current increases in the motor circuit. The needfor compensation depends on application and motor.Typically small motors require more compensationthan big ones. Over compensation occurs as twichingof the motor.CONTROLLINGThe max value of controlling voltage ranges ±( 5...10V ). Thefull range is thus maintained on 0...5V.
