11.6 Connection Methods
Using a DRIVE CLiQ Hub Module
A DRIVE-CLiQ Hub Module (DMC20 or DME20) can be used to double the maximum
permissible cable length for MOTION-CONNECT cables with RJ45 connectors. After the
hub, the same length conditions apply as before the hub.
ΣMC500 + 4/3 * ΣMC800PLUS + n
ΣMC500 + 4/3 * ΣMC800PLUS + n
It is possible to connect two DRIVE-CLiQ Hub Modules in series (cascade connection).

Power cables for motors

11.6.2.1

Configuring the cable length

The ohmic losses of the motor cable must be less than 5 % of the Power Module power
rating.

A cable length up to 150 m is possible for C2 if you use an unfiltered Power Module with an external line filter for
1)
Category C2 and a motor reactor.
Also observe the restrictions for 6SL3210-1PE27-5UL0 and 6SL3210-1PE31-1UL0 Power Modules
2)
● Motor cable length, 50 to 100 m: Set the pulse frequency to 2 kHz.
● Motor cable length > 100 m: Reduce the base load current for each 10 m by 1 %.
