Constant load (linear characteristic)
Speed-dependent load (parabolic charac‐
teristic)
14.10 Closed-loop drive control
•
Setting for all applications without speed-dependent
load characteristic
•
High load torque even at low speeds
•
Setting, e.g. for parabolic load characteristics for
pumps, fans
•
Only small load torques at low speeds
•
Full load is reached at the rated operating point
•
If high load surges in the range of low and medium
speeds cannot be ruled out, we recommend setting
p501 = 0.
