Introduction
Device function
This section describes the device functions. All the device functions are assigned inputs (e.g.
device parameters) and outputs (e.g. messages).
The following schematic diagram illustrates the functional principle of the device:

Further details regarding device parameters and their change options can be found in the
chapter entitled Parameterizing
Self-protection
The motor protects itself against fatal damage by means of the thermal motor model and
temperature measurements for electronic switching elements. If the self-protection responds,
● the motor and the brake output are switched off immediately!
● the "switching element overload" signal is generated.
Switching on with "emergency start" is not possible.
Currents
Note
All current values (e.g. blocking current, current limit values) are percentages of the rated
operating current set on the device (e.g. I
e
= 2 A = 100%).
