Description
87Hz Drive
If you use a drive on 87 Hz, the drive can deliver up to 1.7 times its nominal power. This
results in a smaller drive to do the heavy lifting. If you use this 87 Hz technique, you must
consider the following:
•
how to wire the drive
•
the power of the frequency inverter
•
the use of a breaking resistor
Refer to the Qimarox specification sheet for drive parameters. The next figure shows an
example of a drive that is used at a higher frequency.
•
Frequency: indicates at which frequency the drive has to be controlled by the
frequency inverter to reach the speed and capacity stated in the specification sheet.
•
Connection type: indicates how the drive needs to be connected.
•
Regenerative power: gives the maximum power a braking resistor needs to dissipate
when the machine lowers a full load at the speed stated in the specification sheet.
•
Minimal power frequency inverter: indicates the maximum power that the drive uses.
