905 Error limit switch monitoring This error occurs under the following conditions:
Case a: Both hardware limit switches set simultaneously.
Case b: Positiver software limit switch and negative hardware limit
switch active simultaneously.
Case c: Negative software limit switch and positive hardware limit
switch active simultaneously.
Possible causes:
- Software limit switch set incorrectly, such as values for positive and
negative limit switches are reversed.
- Hardware limit switches are wired incorrectly.
- Errors on the cable for hardware limit switches.
No response
906 Negative hardware limit switch overrun Negative hardware limit switch overrun No response
907 Positive hardware limit switch overrun Positive hardware limit switch overrun No response
908 Negative software limit switch overrun Operating mode Position Target Specification:
Target position to be approached is smaller than the negative soft-
ware limit switch.
Other operating modes:
Position set value is less than the negative software limit switch.
No response
909 Positive software limit switch overrun Operating mode Position Target Specification:
Target position to be approached is greater than the positive soft-
ware limit switch.
Other operating modes:
Position set value is greater than the positive software limit switch.
No response
910 Overspeed detected at set value input Overspeed detected at set value input:
Set values were set in the operating mode Position Control with
cyclical set value position default (-4). These exceed the set speed
limit (parameter
Z121.11–), the permitted mechanical maximum
speed of the motor (parameter Z121.11–) or the maximum interpo-
lated set speed.
If the error reaction „No Reaction“ occurs, the error is displayed and
the set speed is limited to the limit (
Z121.11– or Z107.26–). There-
fore, the input- and the output position drift apart.
The operating mode „Synchronism“ (-5) detected a speed (= master
axis speed) at the gear input. This causes an overflow at the set
gear output of the gear ratio.
At error reaction „No Reaction“ the error is displayed. The speed
attempts to reach the permitted limit via the synchronization mecha
-
nism.
Other error responses:
The active operating mode will be terminated and the drive will be
decelerated according to the preset error response
The error can be reset at any time.
