5.3.1 Connecting the motor brake (X2)
The brake is an integral part of the motor. See requirements for the brake
. The
brake wires are typically part of the motor cable. They are connected to X2, see constraints on wire
cross section in
The brake wires are connected as follows:
Terminal no.

Maximum allowed current to the brake is 5 A DC.
5.3.2 Connecting the temperature sensors (X3, optional)
If the motor temperature sensor wires are not in the resolver cable, the sensor is connected to X3.
(Never connect the same sensor to both X3 and X4 connectors.) If Pt100 is used as motor sensor, it
must be connected to Pt 4, and Pt 4 is then configured as motor temperature sensor (KTY 84 is the
