Specification of the installation methods for axis and supply
modules
Selection of the required ECS supply module
The best way to select the ideal ECS supply module for a multi-
axis application is to use a time/power diagram for a complete
ECS servo system axis and supply modules are available in
three different versions:
machine cycle for all axes. The total power characteristic can
be calculated by adding the time-based individual axis power
ƒ
as built-in units for fixing to an appropriate mounting
plate in the control cabinet
ratings and used as the basis for selecting the most suitable
ECS supply module.
ƒ
in a push-through technique (thermal separation) design,
in which the heatsink is plugged into the modules via the
backplane of the control cabinet or other assembly space
so that the heat loss is dissipated directly outwards.
ƒ
as a cold-plate unit. In this version, the ECS modules do
not have their own heatsinks, but are mounted directly
on an existing heatsink in the customer system via the
rear-side mounting plate.
