SIMOREG DC Master Operating Instructions
3.4 Technical data
3.4.1 Load types
To adapt the SIMOREG DC Master to the load profile of the working machine as efficiently as
possible, you can dimension it using the load cycle.
The setting on the SIMOREG DC Master is made in parameter P067.

NOTICE
If you set a value of > 1 in P067, you must ensure that the "Dynamic overload capability of
power module“ is enabled, i.e. a value of > 0 must be set in parameter P075.
The SIMOREG DC Master does not
monitor for compliance with the criteria of the load class
set in parameter P067. If permitted by the power module, the unit can operate for overload
periods in excess of those defined by the load class. The actual permissible overload period for
the installed power module is always longer than the overload period defined for the load class.
The SIMOREG DC Master does monitor
the actual permissible overload period for the power
module. See Section 9.15.
