121.11 Speed limit
Bipolar limit to limit the output speed of the positioning operating modes.
Additionally the Z107.26– 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 Z121.11–
and Z107.26– is effective.
If the value 0 rpm is entered in Z107.26–, the value is ignored at the determination of the
speed limit, i.e. Z121.11– is effective.
Reference run (Operating mode 6):
If the set Z120.5– Homing speed exceeds the effective speed limit (Z121.11– and
Z107.26– respectively), the speed will be reduced to the value of the limit and Bit 6 is set
in the Z120.1– Status.
Position target specification (Operating mode 1) and manual operation (Operating
mode 5):
If the set Z118.11– positioning speed or Z119.3– tipping speed multiplied with the
Z121.7– Feed Rate Override exceeds the effective speed limit (Z121.11– and Z107.26–
respectively), the speed will be reduced to the value of the limit and Bit 6 is set in the cor-
responding operating mode status (Z118.1– or Z119.1–).
Position control with cyclic set value specification (Operating mode -4):
The input position values including offset parameters (Z136.3– to Z136.7–) are moni-
tored for overspeed. If the resulting set value speed exceeds the effective speed limit
(
Z121.11– and Z107.26– 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
Z136.1– Status.
The following applies especially to the input set values Z136.3– Target position and
Z136.4– 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 (Z121.16–) and the gear (Z121.13– and
Z121.14–).
Spindle positioning (Operating mode -6):
If the set spindle positioning speed Z149.4– exceeds the effective speed limit (Z121.11–
and Z107.26– respectively), the speed will be reduced to the value of the limit and Bit 6
will be set in the Z149.1– Status.
NOTE!
For Motion Control applications, the position resolution is permanently set to 65536
Inc/revolution!
The result is a maximum position value of FFFFFFFF
hex
