- the internal voltage protection cannot be interrupted due to a fault response. If an overcurrent condition occurs dur-
ing the active, internal voltage protection, then this can destroy the Motor Module and/or the motor.
- if the Motor Module does not support the autonomous, internal voltage protection (r0192.10 = 0), in order to ensure
safe, reliable functioning when the line supply fails, an external 24 V power supply (UPS) must be used for the com-
ponents.
- if the Motor Module does support the autonomous, internal voltage protection (r0192.10 = 1), in order to ensure
safe, reliable functioning when the line supply fails, the 24 V power supply for the components must be provided
through a Control Supply Module.
- if the internal voltage protection is active, it is not permissible that the motor is driven by the load for a longer period
of time (e.g. as a result of loads that move the motor or another coupled motor).
Remedy: Not necessary.

A07908 Internal armature short-circuit active
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: NONE
Cause: The Motor Module signals that the motor is short-circuited through the power semiconductors (r1239.5 = 1). The
pulses cannot be enabled. The internal armature short-circuit is selected (p1231 = 4):
Remedy: For synchronous motors, the armature short-circuit braking is activated with binector input p1230 = 1 signal.
See also: p1230 (Armature short-circuit / DC braking activation), p1231 (Armature short-circuit / DC braking config-
uration)
F07909 Internal voltage protection: De-activation only effective after POWER ON
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: POWER ON
Cause: The de-activation of the internal voltage protection (p1231 not equal to 3) only becomes effective after POWER ON.
The status signal r1239.6 = 1 indicates that the internal voltage protection is ready.
Remedy: Not necessary.
This a note for the user.
A07910 (N) Drive: Motor overtemperature
Message value: %1
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: NONE
Cause: KTY:
The motor temperature has exceeded the fault threshold (p0604 or p0616).
PTC:
The response threshold of 1650 Ohm was exceeded.
Alarm value (r2124, interpret decimal):
this is the number of the temperature channel leading to the message.
See also: p0604 (Motor temperature alarm threshold)
Remedy: - check the motor load.
- check the motor ambient temperature and cooling.
- check PTC or bimetallic NC contact.
Reaction upon N: NONE
Acknowl. upon N: NONE
