Record selection and positioning records
6.2.1
Function: Record selection and positioning records
In the motor controller, positioning records can be configured to control point-to-point positioning with
trapezoidal velocity curve. The positioning records are selected via record selection “0…63” and they
can be controlled in the individual record/record linking/homing/jog mode via the control data of the
active fieldbus (CANopen/PROFIBUS DP/DeviceNet) or the record selection bit 0…5 of the digital in-
puts. The positioning records “0…63” are permanently assigned to the record selection “0…63”. The
positioning record “0” is reserved for homing. The positioning records “1…63” can be used for the indi-
vidual record/record linking/teach mode
page 114. A profile (0…8) in the positioning record profile
is to be assigned to each parameterised positioning record (1…63)
page 120. Several individual
records in the positioning record list can be linked to a record sequence via the record linking function.
The selected positioning record can be activated with the start command (control data or DIN8). From
the parameters, the controller-internal positioning controller calculates the corresponding positioning
curve for the individual record/record linking/homing mode.
In the Festo Configuration Tool (FCT), the individual record/record linking mode can be parameterised
via the parameters “positioning record list/positioning record profiles” and the homing mode can be
parameterised via the “homing” parameters.
