The CDF3000 does not have a pre-charging circuit. It does not therefore
limit the charging current when the supply voltage is switched on. To uti-
lise the current limiting in the power supply unit, the power should be
switched before the power supply unit (see Fig. 3.4).

Connection Control supply
Please note:
The brake chopper enable threshold and the selection of the braking
resistor are based on the nominal supply voltage.
In the CDF3000, please first set the parameter DCIN to the nominal
value for the supply voltage connected such that U
nom
= |DCIN|
(requirement on supply voltage:
Tolerance max. + 10 %, voltage stabilised and smoothed).
Please note the setting range for the parameter DCIN (24 to 48 V DC).
The brake chopper enable threshold is then calculated as follows:
U
Br
= 1.1 * |DCIN| +5.2 V
The overvoltage shutdown threshold is then calculated as follows:
U
Sp
= 1.1 * |DCIN| +10.2 V
The
