External encoder (X14)
Position Detection and Positioning
The following block circuit diagram applies:
Set the following parameters for the external encoder:
476710667
P
x
= Non-linearized position value of encoder
P
act
= Actual position value for ramp generator and position controller
P941 = Actual position source
P942 = Encoder factor numerator
P943 = Encoder factor denominator
P944 = Encoder scaling external encoder
H510 = External encoder with actual value on variable
H511 = Motor encoder with actual value on variable

encoder
Multiplies the encoder
signals with the set value
Highest value that is smaller than the
ratio between the resolution of the
motor encoder and the external
encoder.
Example: Motor encoder: 4096 Inc. /
ext. encoder 800 inc. = 5.12. Value:
4.
