5-3 Stepping motor setting in EMC2 different coupling type
The life of coupling is affect by the stepping motor speed and the type of processing materials.
We are provided two type of coupling for each user. The first type is flexible coupling and the
other type is simple coupling. The basic comparison table is listed below:
No. Description Flexible coupling Simple coupling Plum Coupling
1. #Velocity(mm’s per sec) Below 25 About 33.33 About 41.7
2. Materials Aluminum Alloy Aluminum Alloy Aluminum Alloy
3. Suggested processing
materials
PCB, wood and
plastic etc.
PMMA and soft
metal.
PMMA and soft
metal.
# This velocity is the same as the “Velocity” parameter in EMC2
Therefore, before you set up the parameter of the velocity in EMC2 for each stepping motor,
please consider the coupling type and processing materials first.
If the velocity setting is too high such as for example, the velocity is 41.7 mm’s per sec with
installed the Flexible coupling, the machine will be produced two situations:
1. The coupling may be broken.
2. The movement of the axis does not smooth and presents sharking.
