Maximum output frequency with
closed-loop 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
SINAMICS S can achieve the specified
values without tuning.
Higher frequencies can be set under the
following secondary conditions and addi-
tional tuning runs:
• Up to 3000 Hz
– Operation without an encoder
– In conjunction with controlled in-
feeds
• Up to 3200 Hz
– Operation with encoder
– In conjunction with controlled
infeeds
• Absolute upper limit 3200 Hz
A license is required tor frequencies
> 600 Hz because of export regulations.
• 300 Hz with 250 μs / 4 kHz
or with 400 μs / 5 kHz
• 240 Hz with 500 μs / 4 kHz
:
If a higher output frequency is required,
consult the specialist support from
SIEMENS.
The derating characteristics in the various manuals must be carefully observed!
Max. output frequency when using dv/dt and sine-wave filters: 150 Hz

sampling times of 125 μs or speed con-
troller sampling times of 125 μs)

Parallel connection of power units No
• Booksize: No

Permissible range of the ratio be-
tween the rated motor current
(p0305) and rated Motor Module
current (r0207)
The permissible range of the ratio be-
tween the rated motor current (p0305)
and rated Motor Module current (r0207)
is, for servo control, 1:1 to 1:4.
With restrictions regarding the torque
accuracy and smooth running operation,
a ratio of up to 1:8 is possible.
The permissible range of the ratio be-
tween the rated motor current (p0305)
and rated Motor Module current (r0207)
is, for vector control, 1.3:1 to 1:4.
With restrictions regarding the torque
accuracy and smooth running operation,
a ratio of up to 1:8 is possible.
