VLT® 7000 Booster
Programming
■ References and Limits 200-228
In this parameter group, the frequency and reference
range of the frequency converter are established.
This parameter group also includes:
- Setting of ramp times
- Choice of four preset references
- Possibility of programming four bypass frequencies.
- Setting of maximum current to motor.
- Setting of warning limits for current, frequency,
reference and feedback.

✭ 50 Hz
Function:
In this parameter, a maximum output frequency
can be selected that corresponds to the highest
speed at which the motor can be.
NB!:
The output frequency of the frequency
converter can never assume a value higher
than 1/10 of the switching frequency
(parameter 407 Switching frequency.
Description of choice:
A value from f
