Thanks aolade for correcting me,
but would you agree with the statement that if you want to say 250HP of output power while your power factor is unity, then you will need buy 250HP input power.
Where as if your power factor is 0.5, then to deliver 250HP of output power, you will need to buy 2...
One thought to share:
HP is calculating the output power which is equal to
Output KW = horsepower *746/(1000*efficiency)
but where you are paying the bill is the input power,
and since power factor, or
input power KW= 1.73 * voltage* amp* power factor
you need higher current to deliver the...
Another neat analogy....
Imagine a thousand horses running through your farm gate, half way through, you decide to slam the gate shut? the horses will destroy it!!!
Now imagine using those circular doors you go through at the hotel that's divided into 4 pieces, when you close off the entrance...
Hi skogsgurra
Thanks very much!
Let me get this straight, so you are saying,
at the activation of estop button, ramp the drive output to zero and then open up the output contactors? And let's say if a delayed opening of the output contacts are what I need, is there a rule to determine the time...
Hello:
Can anyone shed any light on how to properly wire estop circuit to AB 600VAC 3phase AC drive? To be more specific, if you have a field Estop push button, pushing that will deenergize a contactor, and disconnect the output from the drive to the motor. The motor also have brakes that works...
Hello:
Can anyone comment on the Pros and Cons of using RIO communication versus using PLC I/O points for controlling AB PF 700 10Hp AC drives ?
What have lots of spare I/O points on our PLC 5 rack, and we require start forward/reverse, reset and enable signal to the drive and all the field push...
Hello All:
We are currently using a Tachometer (1000RPM = 100VDC) as a feedback signal into the DC drive package.
I was wondering if anyone has seen an application where people tab into this tach signal and feed
an undervoltage DC relay where it will tell us if the motor is up to speed.
There...
