1.5.2 - Current loops adjustments for the 220 VAC amplifier version
Select the right current loops jumpers setting (B1, B2 or B3 position) according to motor and amplifier
specifications.
For the BL and MA 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:
4 A, 8 A, 12 A and 17 A amplifier current ratings
Calculation
of
G = 1,4 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.
30 A, 45 A, 60 A, 70 A and 100 A amplifier current ratings
Calculation
of
G = 1,4 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.
