Lenze EDS4900U-REG - Manual (Page 101)

Configuration
7-10 48XX/49XXSHB0399
7.1.2 Actual value feedback
7.1.2.1 Armature voltage feedback
In speed control with armature voltage feedback, the actual speed signal is
generated ba an internal armature voltage detection. Select C005 = -10- or -40-.
The value under C232 (adjustable 0 ... 30% of C090) compensated for the speed
error generated by the I
ôR component of the armature voltage.
Select the ”I
¼R-compensation” such that the smallest speed occurs between
motor loading and unloading.
Stop!
( Field-weakening operation is not possible with this configuration.
( The monitoring ”Armature circuit interrupted” (ACI) must be solved externally
for this configuration, because an interruption cannot be reliably detected.
