Armature short-circuit / internal voltage protection: Parameterization error
Message value:
Fault cause: %1, motor data set: %2
Drive object:
SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The armature short-circuit is incorrectly parameterized.
Fault value (r0949, decimal interpretation):
zzzzyyxx: zzzz = fault cause, xx = motor data set
zzzz = 1: A permanent-magnet synchronous motor has not been selected.
zzzz = 2: An induction motor has not been selected.
zzzz = 101: External armature short-circuit: Output (r1239.0) not connected up.
zzzz = 102: External armature short-circuit with contactor feedback signal: No feedback signal connected (BI:p1235).
zzzz = 103: External armature short-circuit without contactor feedback signal: Delay time when opening (p1237) is 0.
zzzz = 201: Internal voltage protection: The maximum output current of the Motor Module (r0209) is less than 1.8 x
motor short-circuit current (r0331).
zzzz = 202: Internal voltage protection: A Motor Module in booksize or chassis format is not being used.
zzzz = 203: Internal voltage protection: The motor short-circuit current (p0320) is greater than the maximum motor
current (p0323).
zzzz = 204: Internal voltage protection: The activation (p1231 = 4) is not given for all motor data sets with synchro-
nous motors (p0300 = 2xx, 4xx).
Remedy:
For fault value = 1:
- an armature short-circuit / voltage protection is only permissible for permanent-magnetic synchronous motors. The
highest position of the motor type in p0300 must either be 2 or 4.
For fault value = 101:
- the contactor for the external armature short-circuit configuration should be controlled using output signal r1239.0.
The signal can, e.g. be connected to an output terminal via binector input p0738. Before this fault can be acknowl-
edged, p1231 must be set again.
For fault value = 102:
- if the external armature short-circuit with contactor feedback signal (p1231 = 1) is selected, this feedback signal
must be connected to an input terminal (e.g. r722.x) and then connected to BI: p1235.
- alternatively, the external armature short-circuit without contactor feedback signal (p1231 = 2) can be selected.
For fault value = 103:
- if the external armature short-circuit without contactor feedback signal (p1231 = 2) is selected, then a delay time
must be parameterized in p1237. This time must always be greater than the actual contactor opening time, as oth-
erwise the Motor Module would be short-circuited!
For fault value = 201:
- a Motor Module with a higher maximum current or a motor with a lower short-circuit current must be used. The max-
imum Motor Module current must be higher than 1.8 x short-circuit current of the motor.
For fault value = 202:
- for internal voltage protection, use a Motor Module in booksize or chassis format.
For fault value = 203:
- for internal voltage protection, only use short-circuit proof motors.
For fault value = 204:
- The internal voltage protection must either be activated for all motor data sets with synchronous motors (p0300 =
2xx, 4xx) (p1231 = 3) or it must be de-activated for all motor data sets (p1231 not equal to 3). This therefore ensures
that the protection cannot be accidentally withdrawn as a result of a data set changeover. The fault can only be
acknowledged if this condition is fulfilled.
F07907
Internal armature short-circuit: Motor terminals are not at zero potential after pulse
suppression
Message value:
-
Drive object:
SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction:
NONE
Acknowledge:
IMMEDIATELY
Cause:
The function "Internal voltage protection" (p1231 = 3) was activated.
The following must be observed:
- when the internal voltage protection is active, after pulse suppression, all of the motor terminals are at half of the
DC link voltage (without an internal voltage protection, the motor terminals are at zero potential)!
- it is only permissible to use motors that are short-circuit proof (p0320 < p0323).
- the Motor Module must be able to continually conduct 180% short-circuit current (r0331) of the motor (r0289).
