Linear commutation offset for synchronous linear motors with commutation via
Hall sensors and relative scale. If an absolute scale is used, commutation is set
in
B07
.
The commutation offset can be measured with action B40.
Number of poles of a synchronous servo motor or asynchronous motor.
If the number of pole pairs is specified for third-party motors, the value must be
multiplied by 2 before it is entered.
Correlation between the number of poles, nominal speed n
N
in rpms and the
nominal frequency f
N
in Hz of the motor:
B10
= 2·(f
N
· 60/n
N
).
Nominal output in kW.
If only the nominal torque M
N
is known instead of the nominal output, calculate
B11
according to the following formulas:
•
Rotational motor:
B11
= M
N
· n
N
/9550 (M
N
= nominal torque in Nm, n
N
=
nominal speed in rpm)
•
Linear motor: B11 = F
N
· v
N
/60000 (F
N
= nominal force in N, v
N
= nominal
speed in m/min)
Nominal current in A, as per rating plate.
Nominal speed in rpm for rotational motors, nominal speed in m/min for linear
drives, as per rating plate.
Static torque M
0
(rotational motor) or static force F
0
(linear motor) as per rating
plate. Used as a reference value for torque/force and current limiting (
C03
and
C05
).
Inductance R
U-V
of the motor winding in mH. This value should only be
parameterized for third-party motors. The value can be autotuned with action
B41 autotuning
.
Stator resistance R
U-V
of the motor winding in ohms. Processing with this
parameter is only possible for third-party motors. The value can be autotuned
with action
B41 autotuning
.
Moment of inertia J for synchronous servo motors and asynchronous motors
or mass of the slide for linear motors.
Information
STOBER motors are set to
B05
= 0 in the factory and tested.
Normally no change to parameter B05 is required. For STOBER
motors with absolute value encoder, the commutation offset is
written to the electronic rating plate in the factory and read by the
drive controller at start-up. If
B05
is changed, the overall offset is
considered equal to the rating plate
B05
.
