Dimensions of RS 206419 3. Construction and control elements RS 206419 is designed as a circuit plate with electronic elements, installed on a plate, and covered with a plastic case. Besides electronic components, there are indicating and control elements and connection terminals on the board: - terminal screws for the power supply, motor windings, and control circuit connection; - "START/STOP" and "REVERSE" buttons; - Internal preset potentiometers to adjust motor speed "SPEED", acceleration/deceleration "a" and motor current limit "I". - LED for indication of the controller status. To adjust the motor speed the internal potentiometer "SPEED" and the analog input for voltage signals 0..5 V/0...10 V are provided. To adjust acceleration and reversing deceleration internal potentiometer "a" is provided. To change the motor direction the input and the button "DIR" are intended. To start or stop motion the button and the input "START/STOP" are intended. Adjustment of the protection operation threshold 0.1 ... 5A is carried out by the "CURRENT ADJUST" potentiometer and the "Vref" terminal. 4. Operation principle Regulation of speed and the direction of rotation of a DC brush motor is carried out by a change of voltage value and polarity. This is achieved by including the motor in a bridge circuit on transistor switches controlled by the PWM method. The PWM generator is based on a microcontroller. In addition to the PWM controller, the microcontroller performs the functions of measuring the values of the signal parameters at the control inputs, and the positions of the regulators, calculating the speed, acceleration, and braking according to the internal program. 5. Assembly and connection Please, learn this manual carefully before connection and assembly. 3 rspro.com Please, wire just when the power is off. Do not attempt to change wiring while the power is ON. Please, provide a reliable contact in connection terminals. During wiring, please, observe the polarity and wire management. IMPORTANT: it is recommended to place a power supply in direct proximity to the controller RS 206419. It is obligatory to use a wire cross-section of 1 mm2. The power supply must be able to provide the current 20% higher than the maximum possible current consumption while in operation. Recommended wire length: no longer than 1 m. The connection scheme example is shown in Figure 2. Fig.2. RS 206419 connection scheme (example of speed control by an external potentiometer) 1) Make sure the power supply is turned off. Please, wire just when the power is off. 2) Select input signals logic and voltage range for the analog speed regulation signal (refer to section 7). 3) Connect the motor to the controller terminals A and B. 4) Connect the control elements to the controller according to the chosen speed-adjusting method: - Internal potentiometer - additional connection isn't required - External potentiometer connect a potentiometer to the contacts "SPEED", GND, and "+5V". The internal potentiometer "SPEED" should be turned to the end left position. - Analog signal 0...5 V or 0...10 V connect the source of analog signal to the "SPEED" contacts: "-" to the "GND" contact and "+" to the "SPEED" contact. The motor speed is proportional to the signal voltage. The jumper "10V | 5V" determines the voltage range for the analog speed regulation signal (refer to section 7). 5) If needed, connect control elements to the "START/STOP" and "DIR" contacts. These inputs are clean contact. 4 rspro.com 6) Connect the power supply to the controller contacts: "+" of the power supply to the terminal "VIN", "-" of the power supply to the terminal "GND". Wire cross-section should be suitable for the motor's current consumption. We recommend using a wire cross-section of 1 mm2. Ground the power supply unit. 7) Set speed and acceleration regulators to the end CCW position, which corresponds to their minimum values. 8) Using the potentiometer «CURRENT ADJUST», set the maximum motor current. Adjust the «CURRENT ADJUST» potentiometer and control the set current limit by a voltmeter, connected to «GND» and «Vref » terminals (Fig.3). The motor current limitation can be calculated as: Ilim = 0.1 + 4.9 x (VREF / 3.3) Fig. 3. Connection of a voltmeter for setting a motor maximum current limit 6. Motor Control 1. Choose the method of speed regulation: internal or external potentiometer or analog voltage signal. 2. Connect the motor, power supply, and control elements to the controller according to section 5. 3. Turn on the power supply. The controller is ready for operation. LED at the front panel of the controller should have solid light. Adjust the motor current limit (see section 5). 4. Start the motor by button or input signal «START/STOP». The LED should start blinking (period 1 sec). 5. Adjust the motion parameters by using a speed regulator, acceleration potentiometer, and direction input or button. In case of a short-circuit of motor phases or overcurrent 10A for 15 µs, the controller turns to an emergency mode, de-energizes the motor, and indicates the alarm by LED blinking. In case of motor current exceeds the set limit for 5 sec, the controller also turns to an emergency mode, Red LED blinks. To reset the emergency mode, reset the power supply of the controller. 7. Setting input signals operation logic and voltage range for analog speed control signal The controller RS 206419 provides a few options for processing input signals START/STOP and DIR and 2 options for analog voltage signals. Jumpers for the selection of the necessary options are located on the electronic board under the case of the controller. 5 rspro.com Fig. 4. Take off the case To open the case: · Turn off the power supply. · Disconnect the terminals from the controller; · Remove the controller from the DIN rail; · Open the controller case as shown in the Fig. 4: 1. Press down on the latch with a flathead screwdriver on both sides; 2. Pull the top and bottom of the case apart; · Set the jumpers to the required position 7.1. Setting input signals operation logic As a default, the controller is supplied with standard signal logic: input START/STOP is processed as per the front edge of the signal, and input DIR is processed as per the signal level. Operation logic of the inputs "START/STOP" and "DIR" can be adjusted with the jumpers "START_PIN" and "DIR_PIN" Fig. 5. If the corresponding pair of contacts is closed by a jumper, their state corresponds to the "ON" value. If the jumper doesn't close the contacts, the state of the contacts corresponds to the value "OFF". The logic of operation of the control inputs "START/STOP" and "DIR" is shown in Figure 6. Fig. 5. START_PIN and DIR_PIN jumpers Fig. 6. Operation logic of input signals 6 rspro.com 7.2. Setting voltage range for analog speed control signal Fig. 7. 10V | 5V jumper The voltage range of the analog speed signal can be selected by a customer and depends on the position of the jumper "10V | 5V" Fig. 7. The option is selected if the central contact and the opposite voltage contacts are closed with the jumper. The corresponding voltage contact remains free. This setting should be also taken into account when using an external potentiometer for speed regulation. If use the built-in source +5V and 0...10V setting, the maximum motor speed cannot be achieved. 8. Alarms indication LED on the front panel of the controller indicates the controller operation status. In case of normal operation, the indicator is green. The green indicator blinks during motor operation (approx. 1 time per second). In case errors occur, the LED indicates the code of an error. The number of red blinks represents the alarm code (refer to the table below). LED errors indication Alarm code Alarm Alarm code Alarm 0 Normal operation 4 Internal power switches overheating 1 Out of the voltage range of 5 Wrong motor connection or the internal converter emergency stop (HARD_STOP) 2 Short circuit in a motor 6 Testing the version of the firmware phase 7 rspro.com 9.
