Speed limit
Bipolar limit to limit the output speed of the positioning operating modes.
Additionally the
maximum mechanical speed of the motor for determination of
the effective speed limit in the below-mentioned operating modes is used for the protec-
tion of the motor and the mechanical setup.The lesser value of the parameter
and
is effective.
If the value 0 rpm is entered in
, the value is ignored at the determination of the
speed limit, i.e.
is effective.
Reference run (Operating mode 6):
If the set
Homing speed exceeds the effective speed limit (
and
respectively), the speed will be reduced to the value of the limit and Bit 6 is set
in the
Position target specification (Operating mode 1) and manual operation (Operating
mode 5):
If the set
tipping speed multiplied with the
Feed Rate Override exceeds the effective speed limit (
respectively), the speed will be reduced to the value of the limit and Bit 6 is set in the cor-
responding operating mode status (
Position control with cyclic set value specification (Operating mode -4):
The input position values including offset parameters (
) are moni-
tored for overspeed. If the resulting set value speed exceeds the effective speed limit
(
and
respectively), the speed will be reduced to the value of the lim-
it, the error 910 "Overspeed detected at the set value input" will be triggered and Bit 6 will
be set in the
Status.
The following applies especially to the input set values
Target position and
Target offset:
The limit value monitors the set speed in the drive-sided standardization i.e. after the con-
version of the input set value by weighting (
and
).
Spindle positioning (Operating mode -6):
If the set spindle positioning speed
exceeds the effective speed limit (
and
respectively), the speed will be reduced to the value of the limit and Bit 6
will be set in the
NOTE!
For Motion Control applications, the position resolution is permanently set to 65536
Inc/revolution!
The result is a maximum position value of FFFFFFFF
