{1} 4096 • Only require for speed control with
digital feedback via HTL encoder
• Calculates the gain C0426, depending
on C0425 and C0011
• C0426 will be recalculated aft er ever y
change of C0011 o r C0425.
• Always enter number of increments
divided by number of pole pairs of
the motor!
– Example: Encoder increments = 4096,
motor 4-pole
Þ C0435 = 2048
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! (¶ 16.1-1 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!
l In addition to the free configuration under C0412 you can also
use the fixed assignment under C0007 and C0005:
l Use C0007 to link the function with a digital input.
l Use C005 to select a configuration which evaluates the
frequency input.
1. Enter frequency, resolution, scanning time and type (single-tracked,
two-tracked) of the setpoint signal (C0425).
2. Set the gain and ensure that the input frequency corresponds to the
normalisation frequency at maximum process speed of the motor (C0426).
– The gain always affects setpoint signal and offset.
– 100 % equals gain factor = 1.
