Monitoring Load and Overload (I2T Monitoring)
The load is the thermal load on the power stage, the motor and the braking resistor.
Load and overload on the individual components are monitored internally; the values can be read by means of parameters.
Overload starts at a load value of 100 %.
1 Load
2 Overload
The load can be read using the following parameters:
|
Parameter name HMI menu HMI name |
Description |
Unit Minimum value Factory setting Maximum value |
Data type R/W Persistent Expert |
Parameter address via fieldbus |
|---|---|---|---|---|

In the case of 100 % overload of the power stage or the motor, the current is limited internally. In the case of 100 % overload of the braking resistor, the braking resistor is deactivated.
The overload and the peak value can be read using the following parameters:
