Description
1806
Start–up function, amplitude
–1 600.0
5.0
1 600.0
%
Immedi-
ately
... specifies the amplitude of the signal to be output. The units are dependent on P1804.
if
then
P1804 = 1, 2
the units are referred to P1103 (rated motor current)
P1804 = 3
the units are referred to P1400 (rated motor speed)
1807
Start–up function, offset
–1 600.0
0.0
1 600.0
%
Immedi-
ately
... defines the offset of the signal to be output. The units are dependent on P1804.
if
then
P1804 = 1
the unit is referred to P1103 (rated motor current)
P1804 = 2, 3
the units are referred to P1400 (rated motor speed)
Note:
For P1804 = 2 (”fault torque” mode), the offset does not affect the current setpoint, but the
speed setpoint, to compensate for the effects of backlash (play).
1808
Function generator limiting
0.0
100.0
1 600.0
%
Immedi-
ately
... defines the limit of the signal to be output. The units are dependent on P1804.
if
then
P1804 = 1, 2
the units are referred to P1103 (rated motor current)
P1804 = 3
the units are referred to P1400 (rated motor speed)
Note:
The limit is effective, symmetrically around the zero point.
For P1804 = 2 (”disturbance torque” mode), the limit only acts on the current setpoint, but not
on the speed setpoint (= offset).
1809
Function generator 2nd amplitude
(only for P1805 = 2, staircase)
–1 600.0
7.0
1 600.0
%
Immedi-
ately
... specifies the 2nd amplitude for the ”staircase” waveform. The units are dependent on
P1804.
if
then
P1804 = 1, 2
the units are referred to P1103 (rated motor current)
P1804 = 3
the units are referred to P1400 (rated motor speed)
1810
Function generator period
(not for P1805 = 4, PRBS)
1
1 000
65 535
ms
Immedi-
ately
... defines the period of the signal to be output.
1811
Function generator pulse width
(only for P1805 = 1, squarewave)
0
500
65 535
ms
Immedi-
ately
... defines the pulse width of the ”squarewave” waveform.
1812
Start–up function, bandwidth (FFT)
(only for P1805 = 4, PRBS)
1
4 000
8 000
Hz
Immedi-
ately
... defines the bandwidth in the PRBS mode.
