Cable construction influencing the capacitance
Parallel connection of DC buses
When a number of drives are used in a system, it is possible to connect
their DC buses in parallel in order to allow energy sharing, especially
when one or more motors are being braked. Operation in this manner is
not covered by this Installation Guide; cable sizes and other information
can be obtaine from the supplier of the drive.
Ordering motor cables
Cables of the required lengths and type of sheath, and fitted with
appropriate terminations to suit the drive and CT-Dynamics SL motors,
are supplied by Control Techniques Dynamics Ltd. For ordering, create
the required order code (see below) and contact the supplier of the drive.
The order code is constructed as follows:
See opposite for the details of the code.
The values stated are for 40
