Hi, guys, I am confused on parameter 82, PowerFlex 70.
082 Maximum Speed:
default: 50 or 60 HZ,
min/max: 5.0/500.0 HZ.
Now, we have a motor (60HZ, 1725rpm),
If there is 30 HZ displayed on the drive, what’s the actual motor speed difference 082=60 HZ and 082=300 HZ ?
And we checked the PLC program, there is a function:
actual motor speed (rpm) = XXX (type: int.) / 252.2 * 28
could someone tell us where XXX and 252.2 come from and what their meaning are?
(we know Z = 1725 (rpm) * Y / 60 (HZ) = 28.75 Y.)
Thanks a lot.
