Product description
XDS2 interface for tightening spindle
The tightening spindle is connected to the
Compact System via a spindle connecting cable
that is connected to the 14-pin socket.
The power supply for the motor and the
transmission of the interface signals is provided
via this cable.

1 motor OFF interface XDN1
CAUTION
Risk of damage to persons and property!
Make sure the emergency OFF equipment

is accessible and effective. Releasing the
emergency OFF equipment must not result
in an uncontrolled system restart!
The motor off interface is used to
integrate the tightening controller
into an emergency stop mechanism.
For information about the category
and performance level of the motor
off interface, refer to the technical
information TIe_197 or the project
planning manual.
Two independent motor stop circuits are
available:
• motor off circuit 1 (NH1) is implemented via a
contactor installed in the Compact System.
This separates the motor from the servo
amplifier (motor is braked).
• motor off circuit 2 (NH2) prevents the
development of a motor rotating field (motor is
not braked).
Both connections are bridged in the delivery
state.
