Safety installations
The integrated HBI drives have extensive sensor equipment for the monitoring of the controller, power stage, motor and
communication with the outside. All occurring errors lead to the shut-down of the power stage
(motor de-energised, no torque) and are signalled by the red LED of the status display with a blinking code.
Switching the power stage on again is only possible if the cause of the error has been remedied and the error has been
acknowledged by the control enable.
The
overcurrent
and/or
short-circuit monitor
recognises short-circuits between the motor phases.
The
I²t monitor
protects the motor and power stage from thermal overload by limiting the motor current to rated
current after the lapse of a permissible overload duration.
The overvoltage monitor
triggers as soon as the DC-link voltage exceeds a maximum permissible value.
The
temperature
of the power stage is measured and the power stage is switched off when the temperature exceeds
85°C.
The
signals of the internal angle sensor system
are monitored for valid statuses. Invalid signal combinations lead
to the shut-down of the power stage.
