10.2 Master and stoker

10.2 Master and stoker
The first motor in an axis is called the "master". The master defines the positive direction of
rotation of the axis. The second and each additional motor are called "stokers".
The following definitions also apply to each additional stoker.
Whether tandem or Janus arrangement is the better solution, depends on the space
requirement and the cable routing.
A stoker can be arranged on the axis with respect to the master in two ways:
Tandem arrangement
The stoker has the same cable outlet direction as the master. All power connection phases
must be connected to the Motor Module phases with the same names. The stoker has the
same direction of rotation as the master.

Janus arrangement
The stoker has the opposite cable outlet direction as the master. For the stoker power
connections, interchange phases V and W so that the stoker runs the shaft in the same
direction of rotation as the master.
