6.4.1 Selecting the function of the charging current limitation
The ECS axis modules are provided with a charging current limitation by means of charge
resistors and charge relays. In the Lenze setting the charging current limitation is activated
(C0175 = 1).
At mains connection the charge relay remains open for a while so that the charging current
of the DC bus is limited by the charging resistors. When a certain voltage level has been
reached, the charging resistors are short circuited by switching on (closing) the charge
relay contacts.

ƒ In case of a mains supply via a power supply module ECSxE the entire DC
bus is charged in a controlled way by a semiconductor circuit (thyristor) in
the power supply module. Therefore, set C0175 = 3 for the axis modules
(charging current limitation inactive, charging resistor short−circuited).
If the Lenze setting has been loaded via C0002, C0175 = 3 must be reset.
ƒ Cyclic switching of the mains voltage at the power supply module can
overload and destroy the charging current limitations of the axis modules if
activated (C0175 = 1 or C0175 = 2).
For this reason, allow a break of at least three minutes between two starting
operations in case of cyclic mains switching over a longer period of time!
