: Rising edge of encoder digital input DI1 signal (proximity switch signal) is
detected when the load position should be 90°. The actual position of the encoder is
120° (stored to signal
Distance between the load position and the actual position is 90° - 120° = -30°

Master reference correction
The purpose of the master reference correction is to correct the difference between
and the synchron reference position
at the moment when the triggering conditions are met. If there is a
deviation, a corresponding correction is carried out on the drive synchron reference
position.
Note:
In master reference correction, the follower must always be in synchron
control mode. If the follower is not used in synchron control mode, adjusting the drive
synchron reference (
) will not affect the operation of the
drive, and the correction cannot be carried out properly.
Example:

Information
All position values are in degrees
Positioning is between 0 and 1 revolutions, ie, after
360°, the position calculation starts from 0° again.

Synchron gear ratio is 1.
