■ References & Limits 200 - 228
In this parameter group,
the frequency and
reference range of the
VLT 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.
200 Output frequency range
(FREQUENCY RANGE)
Value:
★ 0 - 120 Hz (0 - 120 HZ) [0]
0 - 1000 Hz (0 - 1000 HZ) [1]
Function:
This is where to select the maximum output
frequency range to be set in parameter 202 Output
frequency high limit, f
MAX
.
Description of choice:
Select the required output frequency range.
201 Output frequency low limit, f
MIN
(MIN. FREQUENCY)
Value:
0.0 - f
MAX
★ 0.0 HZ
Function:
This is where to select the maximum output
frequency range to be set in parameter 202 Output
frequency high limit, f
MAX
.
Description of choice:
A value from 0.0 Hz to the Output frequency high
limit, f
MAX
frequency set in parameter 202 can be
selected.
202 Output frequency high limit, f
MAX
(MAX. FREQUENCY)
Value:
f
MIN
- 120/1000 Hz
(par. 200 Output frequency range) ★ 50 Hz
Function:
In this parameter, a maximum output frequency limit
can be selected that corresponds to the highest
speed at which the motor can be.
NB!
The output frequency of the VLT 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.
