E835 Quick stop with probe detection is active
Probe 1 was parameterized with quick stop. The quick stop was activated
by a positive edge at the probe input 1, i.e. the drive was immediately
decelerated to velocity 0.
Cause:
With the mentioned parameterization, there was a positive edge at probe
input 1.
Remedy:
• Clear parameter S-0-0405, Probe 1 enable
• Deactivate probe function by clearing parameter S-0-0170, Probing
cycle procedure command
• Deactivate probe function by going back to communication phase 2
and progressing again to communication phase 4

E843 Positive limit switch activated
The drive has received a command value which resulted in an axis
position outside the positive travel range. The axis has been brought to a
standstill by setting the velocity command to zero. A class 1 diagnostic
error is not generated. The drive will automatically follow command values
that lead back into the allowed range. Bit 2 of P-0-0090, Travel limit
parameter is set to "Overtravelling is handled as a warning".
Cause:
The positive limit switch has been activated.
Remedy:
Enter command values that lead back into the allowed range.

E844 Negative limit switch activated
The drive has received a command value which resulted in an axis
position outside the negative travel range. The axis has been brought to a
standstill by setting the velocity command to zero. A class 1 diagnostic
error is not generated. The drive will automatically follow command values
that lead back into the allowed range. Bit 2 of P-0-0090, Travel limit
parameter is set to "Overtravelling is handled as a warning".
Cause:
The negative limit switch has been activated.
Remedy:
Enter command values which lead back into the allowed range.
