Commissioning
● Unlike "Dynamic Drive Control," no speed
controller needs to be set
● Compared with the "EXPERT" setting:
–
–
● Standard Drive Control is preset for converters
of frame size A ... frame size C
162
Standard Drive Control
Motor power ratings < 45 kW
Ramp-up time 0 → rated speed (depending
on the motor power rating):
1 s (0.1 kW) ... 10 s (45 kW)
Applications with steady load torque without
load surges
Induction motors
550 Hz
Without torque control
Simplified commissioning using predefined
motor data
Reduced number of parameters
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
● Torque accuracy that can be achieved: ± 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 of 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).
● Pumps and compressors with displacement
machines
Induction and synchronous motors
Speed control with lower-level torque control
● Fewer parameters compared with the
"EXPERT" setting
● Dynamic Drive Control is preset for converters
