Figure 6.48: Chopper transistor
The activation of the internal chopper resistor (option) or of an connection to an external chopper resistor is
made via the connections BA-, Bal and 1C1.
In order to activate the chopper resistor, a wire link between Ba- and Bal is to be connected. At devices
according to type key V1 with internal chopper resistor the bridge is already integrated. In this case thed
internal chopper resistor and the chopper resistor monitoring cannot be deactivated.
The external chopper resistor must be connected between BA- an BA+.
At d evices acc ording to type key V2 chopper resistor monitoring is only active, if the internal chopper resistor
was activated with a bridge. At response of chopper resistor monitoring an error is released independent of a
possibly connected external chopper resistor.
NOTE
The chopper resistor monitoring is ac tivated at recognition of a current flow by the internal
chopper resistor and remains active, as long as the 24V-supply is switched on. In case the
chopper resistor monitoring shall be d eactivated after a changing over to an external chopper
resistor, then the 24V-supply must be switched off and the resetting must be operated without
the bridge, which was mentioned above.
