4.4 Mounting in cold−plate design
The axis modules ECSC... are intended for mounting in cold−plate design (e.g. on collective
coolers).
Requirements for collective coolers
The following requirements must be met to ensure a safe operation of the axis modules:
ƒ
Good thermal contact with the cooler
– The contact surface between collective cooler and axis module must be at least as
large as the cooling plate of the axis module.
– Smooth contact surface, max. deviation 0.05 mm.
– Connect the collective cooler with all specified screwed connections to the axis
module.
ƒ
Maintain the thermal resistance R
th
according to the table.
– The values apply for operating the axis modules under rated conditions.

Ambient conditions:
– Furthermore the rated data regarding the ambient temperature and the derating
factors at increased temperature apply to the axis modules ( 31 et seqq.).
– Temperature of the cooling plate ("Cold Plate"): max. +85 °C
