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. 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 signal for speed governing.
When using 0-5V/0-10V voltage speed governing or 4-20mA current signal 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 signal for speed governing.
AIN/VR connects to voltage signal, 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 signal input, directly connect to AIN/VR &GND. Two resistors should be added for 0-10V voltage signal input as wiring in the diagram below.
3Input 4-20mA signal 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 motor brush.
External CW/CCW switch connect respectively to CW/CCW and 5V connector. 3, Digital Control Connector (isolation).
Outside PWM: External PWM signal input for speed governing. PWM Duty Cycle Range:0-100%. PWM Frequency Range:800Hz-30kHz, recommend using 16kHz, low level effective. Using External PWM Signals 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 motor brush. When using external PWM signal 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 signal 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 signal.
If connected to PLC24V level control, the pin should be connect to a 1.5K-3KO resistor in series. NPN-C: Alarm signal output NPN transistor.
When alarming, the transistor is conducted. Maximum Current: 15mA Voltage Range:3.3-24V. NPN-E: Alarm signal output NPN transistor emitter.
1 Analog Control Connector Signals Setting. 0-5V - PWM: When input signal 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 Signal setting.
Outside PWM: When using external PWM input signal 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 motor, driver from burning-out when motor is over-current or locked-rotor, in the mean time, output protection signal to the PC controller for PLC or control card protection.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 signal input potentiometer (4-20 ma - ADJ) signal matching Settings. Current Input Speed Governing Signal "420mA-ADJ" Potentiometer setting. When potentiometer is used for 4-20mA signal speed governing, control correspondence of signal and rotating speed. Generally it does not need to adjust. If it is found that the actual rotating speed and control signal is not corresponding, you can adjust the potentiometer slightly. 3 PWM Signal 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.
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 signal 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 signal of, some control card use P1 connector, some use P17.
