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?
- Normal, my power adapter is also very hot, generally ignore
- Q: A 4-pole AC motor into a 2-pole AC motor, the motor is controlled by the inverter, to make the maximum speed of the 2-pole motor and the original 4-pole
- First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
- Q: Pump frequency converter instantaneous restart and restart the problem
- Speed tracking start, with them better. Speed search time is less than the free downtime, not too small too much, will be over-voltage protection. I do not understand and contact me. Your inverter voltage level, manufacturers.
- Q: I have a 11KW-4 pole inverter, now with the 4KW-4 pole motor, what impact?
- The inverter burns should be. Your motor overload is relatively large,
- Q: Laptop power adapter aging
- This should be no, play the game automatically shut down should be detected other
- Q: On the notebook power adapter output current and voltage issues
- This look at your computer is what brand if it is DELL may not be charged, some other brands can be used with some can not, if you can use the charge can then only charge time will be longer than the original power supply, the computer no effect, The current is not bigger than the original big line for a long time on the battery and the motherboard is not good!
- Q: Delta VFD-F frequency converter how to adjust the number of poles
- Look at the 07 motor parameters, I VFD-F instructions need, then the mailbox sent
- Q: Octopus AC Servo motor can be driven with ordinary inverter?
- If it is asynchronous motor, then take the power, voltage matching ordinary inverter drive no problem, you only need to enter the appropriate parameters, such as current, power size and other parameters, and then off-line parameters from the adjustment (if the vector control run), you can run
- Q: Short-term short-circuit converter DC link positive and negative will damage the inverter?
- This short circuit may not necessarily line, the inverter fan has three, one is no speed line, two are pulse, three are switching signal (this is very little, I only encountered several),
- Q: How to learn the inverter debugging and design parameters
- You can find the basic inverter manual, see a few times to try, under normal circumstances, the inverter on the use of manual functions such as research to understand that most of the applications are no problem.
