Function
Notice | |
Preventing a delay in the Gantry Brake By configuring the function, you can reduce the delay in case of error. A delay due to mechanical stress in the Gantry Brake can lead to damage to the axes used. |
A Gantry Brake is an axis with two or more rigidly coupled motors. These motors must be moved synchronously with each other. If the drives are not moved synchronously, the mechanics may jam or be damaged. Synchronous movement must be maintained at the best possible level even in the event of a drive error. For this reason, it is important that all drives on the Gantry Brake react to the occurrence of a drive error with almost no time delay. The function described here makes it possible for all drives of the Gantry Brake to react to an error with almost no time delay. The communication time that normally exists from the faulty drive to the NC or CNC and from there to all other drives is eliminated by this function. The function is parameterized via parameter P-0-0340 "Error propagation configuration" and P-0-0341 "Gantry brake configuration".
The figure below shows two AX5yxx servo drives that are wired to each other via the digital inputs and outputs on connection X06.
Possibilities for error coupling:
- Internal coupling with a delay time of < 100 µs; only possible with two-channel servo drives
- External coupling via jumper on connection X06 of the servo drive. The delay time is < 100 µs.
- External coupling via NC or CNC. The delay time is equal to four EtherCAT cycles.
