This PWM DC motor speed controller (model DM103AH) is mainly used to drive a brushed DC motor, designed for motion control cards or PLC controlling DC motor. It has function of speed governing, on/off, CW/CCW rotation, locked-rotor alarm output, over-current protection, short circuit protection and status indication. The speed controller can control motor with sorts of motion control cards, PLC, and also it can control motor independently. It can be set to control different models brushed DC motors of voltage 20V-110v, and power less than 2000W. It can be used individually through external switch and knob; can also be used with PLC, motion control card, industrial personal computer. With complete function connector, it can connect to external 0 to 5v, 0-10v, 4-20mA, PWM and external potentiometer manually, a total of 5 kinds of speed governing control ways. Designed with ON/OFF connector, CW/CCW rotation connector and protection output connector. Support AC or DC input, there is no worry about burn-out by reverse input. Wide power supply range from AC15V to 110V (50/60Hz), DC 20V to 150V. It has power indicator light, green light for power indicator, red light is alarm indicator. This driver can also be used to drive boiler heat wire, vibration plate, electromagnetic machine, suitable for non-capacitive loads within 2kW. 1, High Voltage Connector. ACIN: Power input (no need to distinguish “+” or “-“). Power Input:AC15V-110V(50/60Hz), DC20V-150V. 5V:Power supply 5V output pin. AIN / VR:Analog input. This connector can connect to three kinds of for speed governing. When using 0-5V/0-10V voltage speed governing or 4-20mA current to speed governing, need to set 4-digit DIP switch. 1Potentiometer Speed Governing:5V, AIN/VR, GND connect respectively to three pins of a 10kR potentiometer to manually control speed; At the same time, the 4-digit DIP switch is set as “05V – PWM”(SW1 – ON, SW2 – OFF, SW3-OFF, SW4-ON) SW3-OFF; SW4-ON. 2 :Input 0-5V or 0-10V voltage for speed governing. AIN/VR connects to voltage, GND connects to ground. At the same time 4-digit DIP switch is set as “05V – PWM”SW1 – ON, SW2 – OFF, SW3-OFF, SW4-ON. No resistor is needed for 0-5V voltage input, directly connect to AIN/VR &GND. Two resistors should be added for 0-10V voltage input as wiring in the diagram below. 3Input 4-20mA for speed governing. GND: common ground (hot ground, do not touch when power on). ON/OFF: Motor ON/OFFit can connect to an external switch. When not connected to GND, motor is on; when connected to GND, motor is off. The external ON/OFF switch connect respectively to ON/OFF and GND. CW/CCW: motor CW/CCW control connector. Recommended minimum control interval is? 1.5 seconds to protect motor brush. External CW/CCW switch connect respectively to CW/CCW and 5V connector. 3, Digital Control Connector (isolation). Outside PWM: External PWM input for speed governing. PWM Duty Cycle Range:0-100%. PWM Frequency Range:800Hz-30kHz, recommend using 16kHz, low level effective. Using External PWM for Speed Governing:4-digit DIP switch is set as “05V – PWM”SW1 – ON, SW2 – OFF, SW3-OFF, SW4-ON SW3-ON SW4-OFF. DIR: Motor direction control connector. Low level effectiveRecommended minimum control interval is? 1.5 seconds to protect motor brush. When using external PWM input, you can also use an on-off switch to control CW/CCW; 2 wires of switch connect respectively to DIR and COM+5V. EN:Motor enable control pin. When this pin is connected to low level, motor does not run. When not connected or connected to high level, motor runs. When using external PWM input, you can use an on-off switch to control on/off; 2 wires of switch connect respectively to EN and COM+5V. COM+5V: Common wire for above three control. If connected to PLC24V level control, the pin should be connect to a 1.5K-3K? Resistor in series. NPN-C: Alarm output NPN transistor. When alarming, the transistor is conducted. Maximum Current: 15mA Voltage Range:3.3-24V. NPN-E: Alarm output NPN transistor emitter. 4, DIP Switch Settings. 1 Analog Control Connector Setting. 0-5V – PWM: When input is 0-5V or 0-10V voltage input or connected to external potentiometer for manual speed governing, setting is SW1-ON, SW2-OFF, SW3-OFF, SW4-ON. 4-20mA-PWM: When using 4-20mA current speed governing, setting is SW1-OFF, SW2-ON, SW3-OFF, SW4-ON. 2 Digital Control Connector setting. Outside PWM: When using external PWM input for speed governing, setting is SW1-OFF, SW2-OFF, SW3-ON, SW4-OFF. 5, Over-current potentiometer, current input potentiometer, PWM frequency potentiometer setting. 1 Overcurrent/Stall Protection Potentiometer (OCP-SET) settings. Current protection potentiometer, you can set motor over-current protection. OCP-SET adjust potentiometer is motor over-current protection setting potentiometer, function is to stop motor and protect motor, driver from burning-out when motor is over-current or locked-rotor, in the mean time, output protection to the PC controller for PLC or control card protection. Setting “OCP-SET” potentiometer position. Correspondence is as follows. A:In general, a brushed DC motor has large starting current and motor direction reversing current is also large. B:According to situation, adjust the rotation speed as highest, the rotating speed is set to the highest, power off then power on without protection, set point a little larger of red light turning on. If you do not need this function or motor load may change greatly, simply set potentiometer clockwise as the maximum. 2 4-20mA input potentiometer (4-20 ma – ADJ) matching Settings. Current Input Speed Governing “420mA-ADJ” Potentiometer setting. When potentiometer is used for 4-20mA speed governing, control correspondence of and rotating speed. Generally it does not need to adjust. If it is found that the actual rotating speed and control is not corresponding, you can adjust the potentiometer slightly. 3 PWM Input Frequency Potentiometer (PWM – FRQ) Setting. Default is 16kHz, generally don’t suggest to change. If change this setting, working noise of motor, efficiency and machinery resonance point will be changed. You may change this potentiometer setting when default settings isn’t suitable for your requirement of work noise, efficiency and resonance. Clockwise to increase frequency, and counterclockwise to reduce frequency. Adjusting range is 2-20kHz. 1, Support AC or DC input, voltage range DC:+20+150V, AC:15110V. 1 Usually we convert 220V/380V to 110V with a transformer. 2 In some countries, the voltage is 115V, 120V or 127V which will damage the driver. For example, this driver can connect to mains power in Japan directly, but not United States. 3 A transformer is suggested to use and convert mains power into less than 110V to power the driver. 4 Power capacity of power supply transformer depends on load of motor, normally is motor nominal power/0.8 and can be a litter larger. For example, 500W motor, 500/0.8 = 625W, choose 600W or 650W transformer. Speed controller be used with PLC, control card, SCM for speed governing. Set 4-digit DIP switch as “Outside PWM”(SW1-OFF, SW2-OFF, SW3-ON, SW4-OFF). 1COM+5V: Connect a resistor (1.5kR-3kR) in series to COM or power 24V+ of PLC. Outside PWM: Connect to PWM IO connector of PLC. 2 Use a high/low level IO1 connector to connect DIR. 3 Use a high/low level IO2 connector to connect EN. COM + 5V:Connect to control card 5V. Outside PWM:PWM of, some control card use P1 connector, some use P17.
