URRENT LOOPS ADJUSTMENTS
1.5.1 - Current loops adjustments for the 400 VAC amplifier version
Select the right current loops jumpers setting (B1, B2 or B3 position) according to motor and amplifier
specifications.
For the 400VAC version of the BL MAVILOR motor series, the current loops adjustments are made according to
following selection table.

For other motors the adjustment of the current loops according to the
amplifier current rating
and to
the
inductance between the motor terminals
is made as follows:
15 A and 30 A amplifier current ratings
Calculation
of
G = 0.8 x Amplifier current rating (A) x Inductance between phases (mH)
,
If
G < 60
, current loop jumpers (x3) on
B3
position,
If
60 < G < 100
, current loop jumpers (x3) on
B2
position,
If
G > 100
, current loop jumpers (x3) on
B1
position.
45 A and 60 A amplifier current ratings
Calculation
of
G = 0.8 x Amplifier current rating (A) x Inductance between phases (mH)
,
If
G < 100
, current loop jumpers (x3) on
B3
position,
If
100 < G < 250
, current loop jumpers (x3) on
B2
position,
If
G > 250
, current loop jumpers (x3) on
B1
position.
