Use only motor cables that have been approved for operation with the servo drive from Festo.
Motor cables of other manufacturers are permitted if they meet the specified requirements.

[X6B], Motor auxiliary connection
The connection [X6B] is located on the front side of the device. The holding brake of the motor and the
motor temperature sensor can be connected to the connection [X6B]. The output for the holding brake
is used both functionally and in connection with the safety function Safe brake control

To monitor the motor temperature, the following are supported:
–
N/C and N/O contacts
–
KTY 81 … 84 (silicon temperature sensors)
–
PTC (PTC resistor, positive temperature coefficient)
–
NTC (negative temperature coefficient)
–
Pt1000 (platinum measuring resistor)
The servo drive monitors whether the motor temperature violates an upper or lower limit. With switch-
ing sensors, only the upper limit value can be monitored (e.g. with a normally closed contact). The lim-
it values and the error reactions can be parameterised.
