What has to be considered regarding the temperature monitoring when an external brake resistor is used?
Answer:
The monitoring of the supply module's internal brake resistor (indication OC6) is to be deactivated (C0579 = 3). Otherwise the error OC6 (error internal brake resistor) will be indicated, although the external brake resistor is correctly connected.
The external brake resistance is monitored using the external temperature contacts (terminals T1 and T2). In case of an error OH3 is indicated. This temperature monitoring is also active when the monitoring of the internal brake resistor (OC6) is deactivated.
