Electronic Line shaft Software allows one or more GPD515/G5 driven motors to be synchronized to a master encoder 
signal. The master encoder provides a pulse reference to the follower that results in the follower commanding its motor to 
maintain a specific shaft position. The follower drive monitors the pulse feedback from the master encoder and its own 
encoder. The follower will then compensate for any position errors by adjusting its motor’s output speed, resulting in near 
perfect alignment between the system master and the follower motor. There is no accumulation of position error, so 
alignment will always be maintained. 
 
The follower also possesses an electronic gearing feature. This allows the follower to operate at a ratio of the master as 
though the two were mechanically coupled through belts or gearing. This software includes “Enhanced” Modbus 
communications. 
 
The registration control feature allows the follower drive to accept a registration mark from the moving product and 
regulate its angular position. This is used for special applications such as packaging machines, flying cutoffs, label 
applicators, etc. 
 
Note: This software can be enabled and disabled using parameter P2-07.

Note: Reference source when electronic line shaft is disabled is determined by parameter b1-01.

Note: This software requires that the PG-W2 Dual Encoder Feedback Option Board (CDR001040) be installed on 
the follower. Both the master reference encoder and the follower encoder need to be of the line driver and 
quadrature type. The registration sensor, if used, must be line driver type also. Hardware jumper HDR1 on the 
PG-W2 board must be set to “up” position for this software to work properly.
