4.4.3 Personnel safe holding brake control
The servo drive has a high level of functional safety of the control of the holding brake.
If it is necessary to have a personnel-safe control for the holding brake, this requires one
or two additional safety contacts in compliance with the safety standards in the +24 V-BR -
line.
Even in this case a mechanical defect in the holding brake can cause injury
and/or machine damage.
