1) Always observe specifications/limitations prescribed by
the encoder supplier.
2) 150m cable is possible up to 500kHz clock frequency,
above 500kHz cable length must be limited further.

1) This is maximum load when only one supply voltage is
used; when 2 or 3 supply voltages are used simultaneously
the load must be reduced accordingly. The following must
be observed: load24V + load8V + load5V 6W and load8V +
load5V 2W.

1) This is the static accuracy; dynamic accuracy depends on
many "external" factors such as encoder resolution,
moment of inertia, mechanical backlash and elasticity.
