Operating Manual
Cabinet Unit Settings
If the braking resistor thermostat is connected to digital input 11, 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:
Setting the "Expert" access level on the operator panel
<Key pushbutton> - <access level> - set "Expert" and confirm -
enter activation code "47".
For operation via terminal strip:
Connect "External Fault 3" to DI 11.
"Expert" access level
Activate CDS 0
MENU - Settings - Data Set Selection - Command Data Set -
Set (CDS) to "0".
The following query is displayed: "Save data in drive too?".
Choose "No".
p2108[1] = (03) 4022.11
Activate CDS 1
MENU - Settings - Data Set Selection - Command Data Set
Set (CDS) to "1".
The following query is displayed: "Save data in drive too?".
Choose "No".
For PROFIBUS operation:
Connect "External Fault 3" to DI 11.
p2108[0] = (03) 4022.11
p1240 = 0
Blocking the Vdc-max controller
The vdc-max controller must be switched off when the brake
chopper is used.

Diagnostics
If the thermostat is opened due to a thermal overload on the braking resistor, fault
F7862 ("External Fault 3") is triggered and the drive is switched off with OFF2.
The braking chopper is not monitored using the software because it has a self-
protection function. It can be monitored using the status bit for digital input 4
(parameter r0721.4):
•
r0721.4 = 1: Chopper is functioning properly
•
r0721.4 = 0: Chopper is malfunctioning
You can acknowledge malfunctions by pressing the "Acknowledge" key on the
operator panel (when the DC link voltage is present).
