SINAMICS S120 Motor Modules in Chassis and Cabinet Modules formats on one CU320-2 Control Unit with firmware 4.3:
Interdependencies the between number of axes, associated current controller cycle and settable pulse frequencies
For maximum possible output frequencies and the current derating factors applicable at increased pulse frequencies,
please refer to section "Rated data, permissible output currents, maximum output frequencies". Further information
can be found also in the function manual "SINAMICS S120 Drive Functions".
With firmware version 4.4, a minimum current controller clock cycle of 125 μs can be set in vector-type drive objects
with SINAMICS S units in Chassis and Cabinet Modules formats. The only exception are the SINAMICS S parallel
converters for which a minimum current controller clock cycle of 200 μs can be set.
The maximum possible output frequency is thus 550 Hz in the standard firmware. When the license "High output
frequency" for SINAMICS S is purchased, the maximum possible output frequency is 650 Hz for units with f
Pulse max
=
8.0 kHz and a current controller clock cycle of 125 μs, and 623 Hz for units with f
Pulse max
= 7.5 kHz, where in the
latter case f
Pulse
must be set to 7.477 kHz and the current controller clock cycle to 133.75 μs.
The maximum possible number of axes which can be connected to a CU320-2 is therefore generally limited to one.
