Configure a Line Speed Signal
The line speed signal is the main reference for the speed or current regulator
in the follower drive(s).
In the Master drive:
• Configure an analog output for the main speed reference (1 “Spd Ref
Out”)
In the Follower drive:
• Set Par 80 [Anlg In3 Sel] to 12 “UserDefined0”
• Set Par 786 [PID Source] to 8695 (503 + 8192). “503” = the parameter
number to which the signal from analog input 3 is sent (Par 503
[UserDefined0]), and “8192” is a drive internal fixed offset value.
