DOK-ECODR3-DKC16*UL***-IB01-EN-P
CAUTION
Damages by exchanging the connectors X6.1-3
and X6.4-6!
⇒
Do not exchange connectors X6.1-3 and X6.4-6.
⇒
Only use lines with sufficient cross section.
⇒
Strong mechanical influence on the test tap of the
terminals can increase the transition resistance and
destroy the terminals.
Motor temperature monitoring (TM+, TM)
Connections TM+ and TM- are used to evaluate the temperature of
connected Rexroth motors. These are equipped with a temperature-
dependent resistor (either PTC or NTC dependent on the motor type) to
monitor temperature. The connection leads are in the motor power cable.
