■ 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.

201 Output frequency low limit, f

MIN

(MIN. FREQUE NC Y)

Value:

0.0 - f

MAX

✭ 0.0 HZ

Function:

This is where to select the minimum output frequency.

Description of choice:

A value from 0.0 Hz to the Output frequency high limit,

MAX

frequency set in parameter 202 can be selected.

202 Output frequency high limit, f

MAX

(MAX. FREQUENC Y)

Value:

MIN

- 120 Hz

(par. 200 Output frequency range)

✭ 60 Hz/

50 Hz

) Global factory setting different from North

American factory setting.)

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

MIN

to the choice made in parameter

200 Output frequency range can be selected.

✭ = factory setting. () = display text [] = value for use in communication via serial communication port
