Technical data

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.

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.
