Notes:
· The maximum attainable output frequency value for SINAMICS S converters described in this engineering
manual for vector-type drive objects in vector control mode is 550 Hz. With the license "High output
frequency", it is possible to increase the output frequency to maximum 650 Hz for SINAMICS S units. To
achieve this output frequency, a power unit is required, which is designed for a maximum pulse frequency of
8.0 kHz (table above), which is not operated in a parallel connection, and which operates with a current
controller clock cycle of 125 μs (settable on SINAMICS S with firmware version 4.4 or higher). In the case of
power units which are designed for a maximum pulse frequency of only 7.5 kHz (table above) and are not
operated in a parallel connection, the maximum attainable output frequency is 623 Hz. To obtain this output
frequency, a current controller clock cycle of 133.75 μs is required (settable on SINAMICS S with firmware
version 4.4 or higher) and a pulse frequency of 7.477 kHz.
· By altering the current controller clock cycle in the range between 125 μs and 500 μs (with SINAMICS S) or
250 μs and 500 μs (with SINAMICS G), it is possible to set other pulse frequency values than those stated in
the table above, although it must be noted that the three equations (1) to (3) on the previous page must still
all be satisfied simultaneously. However, when units communicate in isochronous mode (e.g. via
isochronous PROFIBUS), the only permissible current controller clock cycle is 125 μs or whole multiples
