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 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
infeed units
● Up to 3200 Hz
– Operation with encoder
– In conjunction with controlled
infeed units
● Absolute upper limit 3200 Hz
A license is required tor frequencies
>600 Hz because of export regulations.
Optional
(reduces the number of drives from 6 to 5
Motor Modules with current controller sam‐
pling 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 SIE‐
MENS.
