Indicates default parameter. Depending upon the application, the drive may be delivered with other parameters selected.
References and Limits
Parameters 200 through 228
In this parameter group, the frequencies and references of the drive
are set.
This parameter group includes:
-
Setting of ramp times
-
Choice of four preset references
-
Setting four bypass frequencies
-
Setting maximum current to motor
-
Setting warning limits for current, frequency, reference and
feedback
200
Output Frequency Range
(FREQUENCY RANGE)
Value:
★
0 to 120 Hz (0 - 120 HZ)
[0]
0 to 1000 Hz (0 - 1000 HZ)
[1]
Function:
Choose one of two maximum output frequency ranges.
Description of choice:
Select the output frequency range that includes the highest output
frequency required for normal operation.
WARNING
!
HVAC applications will almost never require
output frequency greater than 120 Hz. Check
with Danfoss Graham, manufacturer of motor,
and manufacturer of driven equipment before
selecting 1000 Hz range.
201
Output Frequency Low Limit
(MIN. FREQUENCY)
Value:
0.0 to parameter 202
★
0.0 H
Z
Function:
Set the minimum speed at which the motor is to run.
Description of choice:
A value from 0.0 Hz to the Output Frequency High Limit
frequency set
in parameter 202 can be selected. The drive will not be able to run
continuously at an output frequency below this value in any mode.
202
Output Frequency High Limit
(MAX. FREQUENCY)
Value:
Parameter 201 to parameter 200
★
60 Hz
Function:
Set the highest speed at which the motor is to run.
NOTE
Output frequency of drive can never assume
value higher than 1/10th of switching frequency.
See parameter 407,
Switching Frequency.
Description of choice:
A value from the choice made in parameter 201 to the choice made in
parameter 200 can be selected. The drive will not be able to run
continuously at an output frequency below this value in any mode.
WARNING
!
HVAC applications seldom require output fre-
quency greater than 60 Hz. Check with Danfoss
Graham, manufacturer of motor, and manufac-
turer of driven equipment before selecting
maximum frequency greater than 60 Hz.
NOTE
For fan applications, factory setting of param-
eter 201 is 6 Hz. For pump applications, factory
setting for parameter 201 is 18 Hz.
