Q:Huichuan frequency converter drag a 4-kilowatt four-pole motor to change the six pole can?
Is the inverter must be. Do not know you are also a generic vector. If it is common to directly on the instructions on the motor logarithmic change 6 pole, turn the number changed to 980 on the line. Vector, then change the number of 980 and then learn from the line on the line.
Q:380V motor addition to the inverter, but also how to change its speed?
Use the star connection to reduce the speed by changing the torque
Q:The laptop's power adapter can be used on a desktop computer
First of all, the desktop is the kind of power, is ups uninterruptible power supply. But relatively large, not directly inside the chassis. In addition, the storage capacity is limited.
Q:What is the single axis of the inverter and multi-axis applications
Inverter is mainly used for AC motor (asynchronous motor or synchronous motor) speed adjustment, is recognized as the AC motor the best and most promising speed control program, in addition to excellent speed performance, the inverter is also significant Energy-saving effect, is the enterprise technological transformation and product upgrading of the ideal speed control device. Since the introduction of China since the 80s of last century, the frequency converter as energy-saving applications and speed of process control more and more important automation equipment, has been rapid development and wide application.
Q:Asus notebook power adapter how to open
Hi respectful ASUS users The power adapter can not be disassembled, and if your machine's power adapter is faulty, you can go to the local service center for testing.
Q:Quartet of the TA, TC terminals have positive and negative?
This can not be said to be positive and negative, should be called the public, TA, is the common.
Q:How to view the parameters of the notebook power adapter on your computer
Notebook power adapter using the correct method] 1. Try to avoid the use of outdoor or harsh environments to prevent the adapter is exposed or damp. 2. When you are not using the adapter, please unplug the power plug. Because, for a long time the power will let the adapter has been in working condition, will affect the end of life. 3. Although the adapter is a broadband operating voltage, marked from 100V-240V can be, but if the voltage is extremely unstable in the case of use, the same will cause damage to the power adapter.
Q:What is the maximum speed adjustable for a 4-stage motor with a rated frequency of 50Hz / 60Hz?
Generally transferred to 60Hz, about 1800 rpm, although the maximum speed when the inverter speed adjustable to 135Hz, but the motor does not work. Bearing first to consider.
Q:Inverter ACS355 If the speed is outside the allowable range, how to set the limit value
2. Set the minimum speed allowed in 2001 MINIMUM SPEED.A positive minimum (or zero) defines two ranges, a positive range, A negative range. A negative minimum defines a speed range.
Q:Inverter alarm a043, how is it
When a signal failure occurs, use the DTI board, if necessary, change P215. With P806 (Follow the parameter description) during operation can be converted to no encoder operation A043 is: n-actjump exceeds the allowable change speed of the speed encoder signal (P215) In addition, for the synchronous motor (P095 = 12): The motor speed is 2% higher than the inverter release time point. The inverter in the ready state can not exit. Check processing: Check if the cable is disconnected Check the tachometer to shield the ground Not only on the motor side but also on the inverter side The encoder cable does not allow disconnection Use only recommended encoders The encoder cable is not allowed to be laid with the power cable
