l C0426 is recalculated after
every change in C0011 or

increments divided by the
number of motor pole pairs!

Activation
1. If you use X3/E1 or X3/E1 and X3/E2 as frequency inputs, you must ensure that the
inputs are not connected to other digital signals:
– These connections must be removed under C0410
– Otherwise the controller will evaluate the digital setpoint signal in a wrong way!
(
¶ 516 ff)
2. Assign the signal source "frequency input" to the required setpoint or actual value
under C0412 (C0412/x = 2).
3. Activation of frequency input with C0410/24 = 1.

Note!
ƒ In addition to the free configuration under C0412 you can also use the fixed
assignment under C0007 and C0005:
ƒ Use C0007 to link the function with a digital input.
ƒ Use C005 to select a configuration which evaluates the frequency input.
