9. Approximate weight of fr-e740-1.5k-cht: 1.9kg
10. Cooling mode of fr-e740-1.5k-cht: forced air cooling
Selection method of fr-e740-1.5k-cht:
1. Fr-e740-1.5k-cht is selected according to the following load torque
characteristics and is divided into the following three categories:
(1) Constant torque load (2) Constant power load (3) Fluid load
2. Fr-e740-1.5k-cht is selected according to the control mode and is divided
into the following five categories:
(1) V / F open loop control (2) V / F closed loop control (3) Vector
control without speed sensor (4) Vector control with speed sensor (5) Direct
torque control
Fr-e740-1.5k-cht selects the protective structure according to the use and
installation environment:
The protective structure of fr-e740-1.5k-cht should adapt to its installation
environment, which requires consideration of environmental temperature,
humidity, dust, pH, corrosive gas and other factors, which is of great
significance to the long-term, stable, safe and reliable operation of fr-e740-
1.5k-cht. It is divided into the following four categories:
(1) Open type (2) Closed type (3) Sealed type (4) Closed
type
1. Select the frequency converter according to the load characteristics,
If the load is constant torque load, Siemens MMV / MDV frequency converter
shall be selected. If the load is fan and pump load, Siemens eco frequency
converter shall be selected.
2. When selecting the frequency converter, the actual motor current value shall
be used as the basis for the selection of the frequency converter, and the
rated power of the motor can only be used as a reference. In addition, it
should be fully considered that the output of the frequency converter contains
high-order harmonics, which will deteriorate the power factor and efficiency of
the motor. Therefore, the current of the motor increases by 10% and the
temperature rise increases by about 20% compared with the power frequency power
grid. Therefore, when selecting motor and frequency converter, this situation
should be taken into account and appropriate allowance should be reserved to
prevent excessive temperature rise from affecting the service life of motor.
3. If the frequency converter wants to run with a long cable, measures should
be taken to restrain the influence of the long cable on the ground coupling
capacitance to avoid insufficient output of the frequency converter. The
frequency converter shall be selected by amplifying the first gear, or the
output reactor shall be installed at the output end of the frequency converter.

4. When the frequency converter is used to control several motors in parallel,
the length of the motor cable and the allowable range of the frequency
converter must be considered. If the specified value is exceeded, the frequency
converter shall be selected by amplifying the first gear or the second gear. In
addition, in this case, the control mode of the frequency converter can only be
Vif control mode, and the frequency converter cannot protect the overcurrent
and overload protection of the motor. At this time, it is necessary to add a
fuse on each motor to realize the protection.
- Q: Is the laptop power adapter high temperature normal? Is there anything else?
- Hello, the power adapter because there are a lot of electronic components so hot is normal, the general hand feels hot does not feel hot on it, if hot, then there is a problem.
- Q: Inverter alarm a043, how is it
- When there is a signal failure, if necessary, use DTI Board, if necessary, change P215 In addition, for the synchronous motor (P095 = 12): the inverter is released until the motor is at rest
- Q: How does the spindle drive system of the inverter realize the positive and negative control of the main pole?
- Communication can reach a longer and more stable, generally better of the city 485
- Q: Laptop power adapter is broken, which brand is better domestic
- This is usually very compatible with the power adapter brand, you can only buy the original, or to the local computer market with a similar output power adapter can be,
- Q: 5.5 kW 4-pole motor with the fastest speed can exceed the rated speed?
- Can not be exceeded Although the inverter can run out of the motor rated speed as the motor will soon burn You want your running speed of 2m / s you have to run 5m / s so go eggs do not pull the
- Q: My inverter is the era TVF8000 series, the motor is 15KW6 pole motor, has been used for 3 years.
- For your situation about the summary of recommendations: First, check whether the motor overload and whether the leakage exceeded, Second, check and clean the inverter fan, if the room temperature is high, add the external fan to the inverter cooling Third, if none of the above, then please check the inverter module is burned, replace the module Fourth, if the inverter is no problem, then the motor and load the problem, if the motor problems are not resolved, then only re-select the inverter, please select the time to increase the margin
- Q: Inverter with 2.2KW 6 pole motor. 1 minute 8 times reversing often burn the motor, how to solve. For the 2 pole 4KW motor is the same.
- 3. Can try (the effect is not necessarily), for a large inverter and variable frequency motor, and the inverter installed braking unit, braking resistor.
- Q: How to choose a power adapter
- With the seller to an output 20V ,, 0.5A IBM single hole power adapter
- Q: Why the notebook power adapter can not be universal
- Second, the voltage is different Different brands of laptop power adapter voltage is not the same, for example: under normal circumstances IBM is 16V, Dell is 20V, Hp is 18.5V, Sony is 19.5V and so on. Thus, even if the power adapter interface is the same, can not use different brands of laptop power adapter for power supply.
- Q: 30 kW 6 pole frequency motor torque is how much
- 30 kW 6 pole frequency motor torque is how much 860. 1, the motor torque calculation Motor "torque", the unit is N? M (beef) 2, the formula is T = 9549 * P / n. 3, P is the motor rated (output) power unit is kilowatts (KW) The denominator is the rated speed n units are per minute (r / min) P and n can be found directly from the motor nameplate.
