SINAMICS G120C Converters
Operating Instructions, 02/2023, FW V4.7 SP14, A5E34263257B AK
Standard Drive Control
Typical settling time after a speed change:
100 ms ... 200 ms
Typical settling time after a load surge: 500 ms
"Standard Drive Control" is suitable to address
the following requirements:
– All motor power ratings
– Ramp-up time 0 → rated speed (depend‐
ing on the motor power rating):
1 s (0.1 kW) ... 10 s (45 kW)
– Applications with steady load torque with‐
out load surges
"Standard Drive Control" is insensitive with re‐
spect to imprecise setting of the motor data
550 Hz
Unlike "Dynamic Drive Control," no speed con‐
troller needs to be set
When compared to "Expert":
– Simplified commissioning using prede‐
fined motor data
– Reduced number of parameters
"Standard Drive Control" is preset for convert‐
ers frame size A ... frame size C
5.5 Quick commissioning with a PC.
Dynamic Drive Control
• Typical settling time after a speed change:
< 100 ms
• Typical settling time after a load surge: 200 ms
• "Dynamic Drive Control" controls and limits the
motor torque
• Typically achieves a torque accuracy: ± 5 % for
15 % ... 100 % of the rated speed
• We recommend "Dynamic Drive Control" for the
following applications:
– Motor power ratings > 11 kW
– For load surges 10 % ... >100 % of the rated
motor torque
• "Dynamic Drive Control" is necessary for a ramp-
up time 0 → rated speed (dependent on the rated
motor power): < 1 s (0.1 kW) ... < 10 s (132 kW).
240 Hz
• Fewer number of parameters when compared to
setting "Expert"
• "Dynamic Drive Control" is preset for converters
