Starting the SyncCrane program
Startup
Scaling the syn-
chronous encoder On this startup screen you determine the position resolution for the synchronous
encoder. If the synchronous encoder is mounted to the motor shaft, some input fields
are disabled and show default values of the motor encoder.

Field Description
Diameter Use these input fields to specify the mechanical data.
You can enter values with two decimal places.
Gear ratio
External ratio
Startup of the synchronous encoder:
Encoder type Choose the encoder type from this field.
Encoder scaling This field is used to enter a value for approximating the physical resolution of the
absolute encoder with the resolution of the motor encoder system.
This selection field directly influences the control behavior of the application module.
Counting direction In this field you can invert the counting direction of the synchronous encoder
depending on the direction of rotation of the motor.
Encoder resolution This field is used to enter the resolution of the absolute encoder.
Calculate The determined position resolution for the motor encoder system is entered in the
input fields "Increments" and "Distance".
The determined scaling factors are limited to 2
16
.
NOTE
If you use a laster distance measuring instrument in the above example, you can
directly enter the resolution specified by the manufacturer, for instance 8 increments/
mm, in the input fields [Increments] and [Distance]. Do NOT press the [Calculate]
button in this case.
