• "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
• 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).
