3.1.3.3 Tacho-generator simulation
A tacho-generator simulation can be used for a voltage range of 7 V
<
UT
<
11 V
.
Terminal
55.2 is used for this purpose.
Adaptation is carried out with short-circuit links:
- Link X21 and X29
- Link X24 and X30
- Link X27 and
X31
(axes
1
and
4)
(axes
2
and
5)
(axes
3
and
6)
When the tacho-generator
simulation
is used, disable the tachogenerator monitoring (see
3.1.3.2
"Tacho-generator
monitoring").
3.1.4 Speed controller adaptation
The reset time TNrated of the speed controller can be set with potentiometers
R135
(axes
1
and 4), R235 (axes 2 and 5) and R335 (axes 3 and 6). In order to adaptively reduce the reset
time TN of the speed controller at lowest speeds, the adjustment module must be fitted with
resistor R15 (axes 1 and 4), R46 (axes 2 and 5) and R77 (axes 3 and 6). The reset time can be
reduced to TNadapt with the following resistance values:
