Tab. 2.36 Teaching in positions
The drive must not stand still for teaching. However, even at low speeds, inaccuracies of several milli
metres are possible, due to the usual cycle times of the motor controller and the higher-order control
ler. The speed must be set during teaching in such a way that the position is detected accurately
enough.
The Teach process always runs in the following steps:
1. The parameter
è
Tab. 2.36 is selected and/or addressed.
2. The actuator is moved into the desired position (e.g through jogging
è
3. A teach command is triggered to adopt the current position.
Teaching with FCT or web server
The taught position is displayed after successful teaching in the software. Parameterisation in the
controller becomes effective through download. Additional information:

Teaching via I/O interface (binary profile)
The number of teachable target positions is limited to 7 sets of commands. The Teach process is per
formed with a handshake process using signals TEACH/ ACK. The taught position is displayed in the
controller immediately after successful teaching. The position is saved permanently using the “Auto
matic saving” option. If this option is not set, permanent saving via FCT or web server is possible.
