* Attention: Set DCIN parameters!
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
minimum
braking resistor allowed is defined by the following table:
