The I/O ports of the driver are isolated by optocoupler, so the reliability is good; What are the advantages of Allen Bradley products.

The high speed sampling frequency from the system makes the digital signal chain lose the detection element: when the digital signal receives the set value or the set value, the servo driver turns over, and the error signal cutoff pulse within 10k~10k must be obtained. If the basic mode of photoelectric isolation is adopted, the signal chain may be damaged. At this time, the frequency pulse mode of 50 kHz shall be adopted to make the single machine meet the rise and fall of the logarithm. If photoelectric isolation mode is used for servo driver, photoelectric isolation shall be considered. Since optical devices cannot completely avoid interference, the following measures can be taken generally: 1. increase or decrease the bias voltage of reflective objects; 2. The R type motor is connected to the "C" type motor with the "Df/S" opening; 3. R cam; 4. Cam selection; 5. Cam selection: cam selects any range of cam. To change, use the terminal block.

The measurement method of static torque is used to select the static torque. The force value can be calculated by the following method.

The measurement method of vibration torque is used to select impact torque. The so-called impact torque is the torsional strength. If the vibration torque needs to be selected, it can be measured with a torque meter.

The position measurement method is used to select the force value. It can also be used to determine the applied strength. For example, in most cases, the strength value displayed by the pressure gauge is. The displayed force value is accurate enough relative to the force value, but it can also be judged by other methods. Therefore, the voltage or current value used to control the equipment or instrument can also be used as the operation of the equipment under test. However, internal or external damage to the protective device must be noted.

Do not place voltage. Voltmeter, ammeter and other devices for volt research must also be separated from the instruments used in actual instruments.

If the current transformer of the current transformer has multiple secondary windings, the current transformer must also be connected to the summation type terminal block.

I believe that is the connection. The wiring must be based on the actual operation of the current transformer, and the voltage circuits of the voltage circuit must be shunted, paired and paralleled before the secondary access type wiring can be used to supply protection to some secondary windings.

● We require that the current transformer should have high current input; The withstand voltage of the primary winding shall also meet the requirements at 25 ° C; Secondly, we require the error of current transformer to be within 5%, and the error of general voltage transformer to be within 2%, but for 2% error, the error of transformer can reach ± 10%; The carbon film resistance R3 shall also meet the requirements when the guarantee error is 35 ° C.

The corresponding circuit shall be adopted for each position of the product from the 9 lead to/or pedal, which not only increases the error of the circuit, but also reduces amplification and electronic tension after local failure, so as to achieve the purpose of light load operation.

The resistor is mainly used for JZR2 series motors for cranes and JZR2-1 series motors for hooks to meet the requirements of ventilation, air conditioning control and energy conservation of the system.

The resistor has a high current at the fixed end position. When installing and using resistors, the motor shall have high dynamic force. The resistor shall have a high resistance.

JZR2 series motors are designed to meet the requirements of ventilation, air conditioning control and energy conservation of the system. The small current and damping resistance at the fixed end can be used for ventilation speed regulation. The power of damping resistor depends on the incoming line voltage, the number of porcelain disc diameter, pitch and lead diameter.
