Commissioning
When commissioning via STARTER, parameters are assigned to "external fault 3" and
acknowledged automatically when option L61, L62, L64, or L65 is selected.
When commissioning via AOP30, the parameter entries required have to be set
subsequently.
Cabinet unit settings
If the braking resistor thermostatic switch is connected to digital input 11 on the customer
terminal block, appropriate settings have to be made so that the drive is brought to a
standstill if a fault occurs.
Once the device has been successfully commissioned, you have to make the following
changes:
Diagnosis
If the thermostat is opened due to a thermal overload on the braking resistor, fault F7861
("External Fault 2") is triggered and the drive is switched off with OFF2.
If the brake chopper triggers a fault, fault F7862 "External fault 3" is triggered in the drive.
You can acknowledge malfunctions in the braking unit by pressing the "Acknowledge" button
on the operator panel when the DC link voltage is present).
