Smart Protection

The problem:
If an error occurs in a motor and the corresponding servo drive, the motor could stop. If the other motors with servo drives cannot respond in good time, a position difference occurs between the system��s individual motors. The problem being that it is possible for the mechanics to cant. High machine repair costs, damage to the workpiece and production standstill can be the consequence. If the machine��s mechanics are designed so that canting does not occur if a drive stops (soft coupling), the failure can be compensated by load balancing of the motors.

The solution:

However, in the case of the rigid coupling, the failure of a motor frequently leads to canting of the machine. In this case, the ��gantry function with synchronous error response�� protection function can be activated. The function can be activated via ProDrive. As a result, both drives can respond synchronously, i.e. at the same time and with the same movement, as soon as an error is detected. Communication here takes place directly in the double axis or via the fieldbus. As a result, there is no time delay. If the error has been corrected, the gantry application can continue, expensive damage to the mechanics is avoided.
