- 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: None necessary.
This a note for the user.
A07908 Internal voltage protection / internal armature short-circuit active
Drive object: SERVO, VECTOR
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.
Remedy: 1) The internal voltage protection is selected (p1231=3):
If the Motor Module does not support the autonomous (independent) internal armature short-circuit (r0192.10 = 0)
then none of the following activation criteria may apply.
- the signal at BI: p1230 (armature short-circuit activation) is 1.
- the drive is not in the state "S4: Operation" or in S5x.
- the internal pulse enable is missing (r0046.19 = 0).
If the Motor Module supports the autonomous internal voltage protection (r0192.10 = 1), then the Motor Module auto-
matically decides - using the DC link voltage - as to whether the short-circuit should be activated. The short circuit is
activated if the DC link voltage exceeds 800 V. If the DC link voltage falls below 450 V, then the short-circuit is with-
drawn. If the autonomous (independent) internal voltage protection is active (r1239.5 = 1) and the line supply returns
(450 V < DC link voltage < 800 V), the short-circuit is withdrawn after 3 minutes. If the motor is still in a critical speed
range, the short-circuit is re-activated once the DC link voltage exceeds the threshold of 800 V.
1) The internal armature short-circuit is selected (p1231=4):
None of the following activation criteria may apply:
- the signal at BI: p1230 (armature short-circuit activation) is 1.
-
F07909 Internal voltage protection: The de-activation only becomes effective after a POWER
ON.
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: IMMEDIATELY
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: None necessary.
This a note for the user.
A07910 (N) Drive: Motor overtemperature
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: KTY:
The motor temperature has exceeded the fault threshold (p0604 or p0616).
VECTOR: The response parameterized in p0610 becomes active.
PTC:
The response threshold of 1650 Ohm was exceeded.
Alarm value (r2124, interpret decimal):
SME not selected in p0601:
1: No output current reduction.
2: Output current reduction active.
SME selected in p0601 (p0601 = 10):
The number specifies the sensor channel that resulted in the alarm being output.
