There are different forms of the "drive-internal interpolation" mode which
result in the corresponding diagnostic messages when the operating
mode was activated (see "Pertinent Diagnostic Messages").

•
drive-internal generation of a position command value profile for
moving to the target position
(
S-0-0258) complying with the adjustable
positioning velocity (S-0-0259) and positioning acceleration (S-0-0260)
or positioning deceleration (S-0-0359); can be set separately
•
jerk limitation of the generated position command value via
S-0-0193,
Positioning Jerk
•
evaluation of the positioning velocity with
S-0-0108, Feedrate override
•
monitoring the positioning velocity for exceeding
S-0-0091, Bipolar
velocity limit value
•
monitoring the target position for maintaining position limit values
•
command value mode in modulo format (shortest distance, only
positive or only negative direction) can be set in
S-0-0393, Command
value mode
•
position control with regard to
S-0-0051, Position feedback 1 value
(motor encoder) or
S-0-0053, Position feedback 2 value
[external
(load-side) encoder]
•
acceleration and deceleration ramps can be set separately
•
no change in direction of movement when command value mode in
modulo format equal "shortest distance", if v
act
> S-0-0417
•
shortest distance when "command value mode in modulo format"
equal "only positive/negative direction of movement" and target
position within
S-0-0418, Target position window in modulo format
Note:
In this operating mode it is possible to separately parameterize
the acceleration and deceleration processes. This allows
optimum adjustment to the respective application-specific
requirements.
