B.. Motor
Para. No. Description
B30
Addit.motor-operation:
Only if
B20
=0 (V/f-control). For multiple-motor operation. Permits an additional motor
to be connected to the enabled inverter. Motor voltage is briefly reduced to prevent overcurrent switchoff.
0: inactiv
e;
1: active;
√
B31
Oscillation damping:
When idling, large motors may tend to sympathetic vibration. Increasing the parameter
B31
damps these oscillations when
B20
=
2:SLVC
. Values from 60 to 100% are suitable for difficult drives.
With
B20
=
2:Vector Control
,
B31
limits the possibility, during generator operation, of using the increase in the
rise of DC link voltage to increase magnetization and thus braking torque. This can have a positive effect on
smoothness of running when the drive is alternating between motor and generator operation at a constant
higher speed.
Value range in %:
0 to 30 to 100
√
B32
SLVC-dynamics:
B32
can be used to manipulate the speed at which SLVC reacts to changes in load.
B32
=100% means greatest dynamics.
Value range in %:

B40•
1)
Phase test:
0: inactive;
1: active;
Tests motor symmetry in increments of 60°. The following points are checked:
- Connection of phases U, V and W
- Symmetry of the winding resistance of the phases U, V and W. If a winding resistor deviates by ±10%, the
inverter reports "
19:symmetry
".
- Type of connection of the motor. If a STÖBER system motor has been selected with parameter
B00
=1 to 28,
the type of connection of the selected STÖBER system motor (i.e., star/delta) is compared with that of the
connected motor. Deviations are reported with "
20:motorConnect.
"
The function is started when the level
on the input enable (X1.9) changes from low to high.
Exiting the parameter requires another low signal on
the enable.

Autotuning:
Determination of the stator resistance
B53
. Important for optimum motor control.
0: inactive;
1: active;
Stator resistance
B53
is measured. The function is started when the level on the input enable (X1.9)
changes from low to high. Exiting the parameter requires another low signal on the enable.
A00
=1 is used to
save the measuring results in non-volatile memory. The HALT signal may not be present and the extra
enable must be present.
B00
=0. Be sure to autotune motor or enter R1-motor
B53
directly. Important for optimum adjustment of inverter
and motor.
B00
=1 to 29, autotuning of the motor is not required. Values are stored in the motor data base.
B53
R1-motor:
Stator resistance of the motor winding, R1=R
u-v
/2. Usually only entered for non STÖBER motors or autotuning with
B41
. In the Y circuit,
B53
directly corresponds to the branch resistance. In the
∆
circuit, 1/3 of the branch resistance must be
entered. With STÖBER motors,
B53
should usually not be changed. The resistance of a cold coil must be entered with an
extra 10% (factor 1,1). R1 is required for correct functioning of the vector control (SLVC and VC). Value is adjusted with
B41
(autotuning). An "*" indicates deviation from the STÖBER motor data base.
