7.1.2.3

Resolver feedback

With the following configurations of C005, a resolver can be used as speed or
phase feedback system. It is connected to X7. Resolver adjustment is not required
since the resolution is determined by the evaluation system. Possible configuration
of C005 are:

-12- Speed control

-42- Torque control with speed limitation

-52- Master with phase control

-62- Digital frequency bar (set-value bar) with phase control

-72- Digital frequency cascade with phase control

7.1.2.4

Incremental encoder feedback

With the following configurations of C005, an incremental encoder can be used
as speed or phase feedback system. It is connected to X5 or X9. An encoder
constant for pulse numbers to the power of two can be directly adjusted under
C025 / C026. Encoder bar number, which cannot be represented as a power of
two, can be adapted using the evaluation factors C027 and C028. Possible
configuration of C005 are:

-13-

Speed control with actual-value feedback via X9

-43-

Torque control with speed limitation
(Act. value feedback via X9)

-53-

Master with phase control (act. value feedback via X5)

-63-

Dig. frequency bar (set-value bar) with phase control
(Act. value feedback via X5)
