Servo control
2600 Hz with 31.25 μs / 16 kHz
•
1300 Hz with 62.5 μs / 8 kHz
•
650 Hz with 125 μs / 4 kHz
•
300 Hz with 250 μs / 2 kHz

Note:
SINAMICS S can achieve the specified
values without optimization.
Higher frequencies can be set under
the following secondary conditions and
additional optimization runs:
Up to 1500 Hz
•
– Operation without an encoder
– In conjunction with controlled
infeeds
Up to 1600 Hz
•
– Operation with encoder
– In conjunction with controlled
infeeds
Absolute upper limit 1600 Hz
•
Reduction of the current setpoint or
shutdown
Optional
(reduces the number of drives from 6 to
5 Motor Modules for current controller
sampling times of 125 μs - or speed
controller sampling times of 125 μs)
No
Vector control
300 Hz with 250 μs / 4 kHz
•
or with 400 μs / 5 kHz
240 Hz with 500 μs / 4 kHz
•
Note:
If a higher output frequency is required,
consult the specialist support from
SIEMENS.
Reduction in the pulse frequency and / or
the current setpoint or shutdown (not
applicable with parallel connection / sine-
wave filter)
Standard
