Potential hazards
Access points for manipulations
The device has interfaces that allow remote access to safety and non-safety functions. In this context, "remote access" means that access is made available directly or indirectly via the local communication interfaces of the device with a software function beyond the physical limits of machine, inverter, and brake. These interfaces allow all parameters to be changed without a safety protocol.
Potential hazards
Potential hazards posed by unauthorized individuals with remote access to the software functions include:
- Manipulation of the speed, resulting in accelerations and decelerations.
- Unintended actuation of the power section, resulting in hazardous movement at the motor shaft.
- Unintended actuation of the brake (brake release), resulting in hazardous movement at the motor shaft.
- Excessive heating of the device and motor, resulting in thermal destruction.
- Manipulation of the safety configuration, resulting in hazardous movement at the motor shaft.
- Manipulation of the motor startup parameters configured in the inverter, resulting in unintended movement at the motor shaft.
- Manipulation of the limit values and digital input settings configured in the inverter (application limits, reference cams), resulting in unintended movement at the motor shaft.
- Manipulation of the encoder configuration of the motor and distance encoder, which may lead to unintended travel behavior or malfunction (e.g., encoder offset).
- Manipulation of the fieldbus interface, which may lead to malfunction.
- Manipulation of the software on the device, which may lead to unintended movement.
- Downgrading of the firmware to an earlier version, which may lead to unintended movement and malfunction.
