Teaching via fieldbus
Absolute position values can be taught via the fieldbus. Previously taught position values will then be
overwritten. Teaching of relative position records, speed records or force records in not possible and
results in warning 0x40 “Last teaching not successful”.
Note: The drive must not stand still for teaching. Of course, imprecisions of several millimetres are
possible even at low speeds due to the normal cycle times of the motor controller, data transmission
and the higher-order controller. The speed must be set during teaching in such a way that the position
is detected accurately enough.
Sequence
1. The drive will be moved to the desired position via the jogging mode or manually. This can be ac
complished in jogging mode by positioning (or by moving manually in the “Drive blocked” status in
the case of motors with an encoder).
2. Parameterise desired teaching target. For “setpoint position in position sets” and the position com
parators, specify the record number in PNU 400 (direct mode) or in control byte 3 (record selection).
