DOK-ECODR3-SGP-03VRS**-WA01-EN-P
E264 Target position out of num. range
Cause:
In modes
• drive-internal interpolation,
• relative interpolation and
• positioning block mode
the previous target position in the internal position format cannot be
reached.
Remedy:
1. Check the given target position and correct, if necessary.
2. With infinitely turning axes it is necessary that the position data be
illustrated in modulo format.
3. The absolute internally illustrable position can be enlarged by
enlarging the maximum travel range.
E269 Brake torque too low
When switching the drive enable off or with the brake monitoring
command, the motor has moved while checking the brake torque. The
motor holding brake thus no longer supplies the nominal torque.
Possible causes for the holding torque that is too low:
1. brake is covered with a layer of oxidization due to storage
2. brake is covered with oil or grease
3. brake is worn down
Remedy of:
1. if the warning occurs when the drive enable is removed, then
start"command brake monitoring".
2. if the warning occurs with the removal of the drive enable, start
"command brake monitoring". The command brake monitoring re-
checks the brake torque. If the torque is too low, then the brake is re-
ground. This re-grinding of the brake removes any residues or films.
The brake should then bring its full torque.
3. if the brake is repeatedly re-ground yet the torque not achieved, then
the motor holding brake must be replaced.

E281 Mains fault
Cause:
The mains voltage has failed during operation for at least three mains
cycles.
In parameter P-0-0118, Power off on error mains failure and
undervoltage failure have been set as warnings.
The drive does not conduct an error reaction. If the drive continues to
operate despite the warning, an F220 Bleeder overload shutdown could
be generated.
