F268 Brake fault
The drive controller takes control of the brake for motors with an
integrated holding brake. The braking current is monitored.
If the braking current is outside of the permissible range between:
0.4 -1.6 * P-0-0511, Break current
this error message will be generated.
Cause:
1. The power supply for the brake is not
connected properly or is outside of the
(24 V +/- 10%) tolerance.
2. The motor cable is incorrectly connected
(wiring error).
3. Defective brake.
4. Defective drive controller.
Note: A connection between the 0V brake supply and the 0V of the
drive controller is required.

F270 Error power supply home switch
To be able to monitor the home switch in drive-controlled homing, the
DSS2.1 plug-in module requires an external 24-V power supply. The drive
monitors the external 24-V power supply if homing with home switch has
been selected via
S-0-0147, Homing parameter (bit 5).
Cause:
The external 24-V power supply of the DSS2.1 plug-in module is missing.
Remedy:
1. Set S-0-0147, Homing parameter to "Homing without home
switch" (bit 5 = 1).
2. Check the 24-V power supply at connector X12 of the DSS2.1
module.
