5 - ADJUSTMENT TO THE MOTOR
5.1 - CONFIGURATION OF THE MOTOR THERMAL SENSOR
Select jumper MN or OP according to the motor thermal sensor type (PTC or NTC).
5.1.1 - THERMAL SENSOR PTC
On motors equipped with a PTC thermal sensor (triggering on high impedance), the amplifier configuration is the
following: MN jumper closed and OP jumper open. The triggering threshold adjustment for the PTC thermal
sensor is made by means of the PSTH components, as described below : PSTH-D = 14,3 k
Ω
; PSTH-B = 28 k
Ω
;
PSTH-A = 3 x RPTC (120°C) in k
Ω
. RPTC (120°C) = ohmic value of the PTC thermal sensor resistor at 120°C;
the default adjustment is RPTC (120°C)

.
5.1.2 - THERMAL SENSOR NTC
On motors equipped with a NTC thermal sensor (triggering on low impedance), the amplifier configuration is the
following: OP jumper closed and MN jumper open. The triggering threshold adjustment for the NTC thermal
sensor is made by means of the PSTH components, as described below: PSTH-D = 14,3 k
Ω
; PSTH-B = 28 k
Ω
;
PSTH-A = 3 x RNTC (120°C) in k
Ω
. RNTC (120°C) = ohmic value of the NTC thermal sensor resistor at 120°C;
the default adjustment is RNTC (120°C)

5.2 - CURRENT LOOPS
5.2.1 - CURRENT LOOPS ADJUSTMENT ON DRIVES WITH 400 VAC SUPPLY
Select the current loop jumpers corresponding to the motor and drive specifications (position B1, B2 or B3).
For the 400 VAC range of the MAVILOR BL motors, the current loops adjustment is made according to the table
below:

On other motor types, the current loops are adjusted according to the
drive current rating
and to
the
inductance between the motor terminals
like follows:
15 A and 30 A DRIVES
- Calculation
of
G = 0.8 x Drive 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 DRIVES
- Calculation
of
G = 0.8 x Drive 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.
