Master-Follower 1.2
3ADT069007R0101 Rev A
Associated application software : MAFO01_2 3ADT40216xR01
Created with : GAD, version 2.43/3, Library DCS500_1.30.
Possible use : DCS500 S21.123 and higher
Tools required : DDC or CMT Tool
Mechanical precondition
- Two motors connected to a fixed shaft
- Each motor requires a tacho-generator or pulse encoder
Limits for this application
- Has been designed for operation in the armature control range
- Identical load distribution only with identical, trimmed motors with an identical field
supply
- Only the master power converter is responsible for the speed; this applies also and in
particular to the "Rapid stop" function.
Control principle
- External preselection of the power converters as single, master or follower
- The power converter which has been selected as the master controls speed and
current, while the one selected as the follower receives the current reference from the
master and only controls the current
- In single-converter mode, the other power converter must remain disabled.
Monitoring features
- The master power converter monitors the ready-for-operation status of the follower.
- The follower drive does not possess an overspeed monitoring function
