d6-01: Field Weakening Level
No.
(Hex.)
Name Description
Default
(Range)
d6-01
(02A0)
Field Weakening Level
Sets the drive output voltage as a percentage of E1-05 [Maximum Output Voltage] when H1-xx = 63
[Field Weakening] is activated.
80%
(0 - 100%)

Field Weakening Frequency
Limit
Sets the minimum output frequency to start field weakening.
0.0 Hz
(0.0 - 590.0 Hz)
Make sure that these two conditions are correct to enable the Field Weakening command:
•
The output frequency ≥ d6-02 .
•
There is a speed agreement status.

d6-06: Field Forcing Limit
No.
(Hex.)
Name Description
Default
(Range)
d6-06
(02A5)
Field Forcing Limit
Sets the limit value for field forcing to increase the motor excitation current reference as a percentage
of
E2-03 [Motor No-Load Current] . Usually it is not necessary to change this setting.
400%
(100 - 400%)
Note:
You cannot use Field Forcing during DC Injection Braking.
◆
d7: Offset Frequency
The drive will use 3 digital signal inputs, to add or subtract the set frequency (Offset frequency) to/from the frequency
reference and correct the speed. The drive uses the terminal set in
H1-xx = 44 to 46 [MFDI Function Select = Add
Offset Frequency 1 to 3] to set the Offset frequency. When you close more than one input at the same time, the drive
adds the selected offset values together.
Figure 12.70 shows the Offset frequency function:
