•
S-0-0260, Positioning Acceleration
In this parameter you have to set the acceleration effective during the
automatic control loop setting.
Note:
The command error C1803 can occur due to the above-
mentioned points but also due to a too high degree of inertia.
In this case the entire drive dimensioning has to be checked, if
necessary.
Velocity Loop (with Respective Filters)
Brief Description
In operation with encoder (closed-loop) the drive firmware, apart from the
field-oriented current loop, also closes the velocity control loop in the drive
(PI cascade structure).
Note:
The kind of motor control can be selected via
P-0-0045,
Control word of current controller
(bit
14).
The use of this function requires the firmware package for
closed-loop operation (see "Functional Packages" in chapter
"System Overview").
