F2177 Modulo limitation error of motor encoder

Cause
S-0-0103, Modulo value or S-0-0278, Maximum
travel range have been incorrectly parameterized
and not adjusted to the application
Drive was moved as rapidly that recalculation no
longer works correctly

F2178 Modulo limitation error of optional encoder

Cause
Encoder speed was so high that recalculation no
longer works correctly

Supported by Firmware Variant:
With active modulo scaling the drive limits its actual position values to the
values parameterized in S-0-0103, Modulo value, otherwise to the value
parameterized in S-0-0278, Maximum travel range. As these values
possibly cannot be exactly displayed, the corresponding recalculation of
the systematic errors in the case of position overflow takes place in the
drive.
Note: In the ideal case S-0-0278, Maximum travel range is set in
such a way that the drive always is within the defined travel
range and there is no overflow.
Remedy
Check and, if necessary, correct S-0-0103, Modulo
value or S-0-0278, Maximum travel range
Reduce drive velocity at position overflow

Display: F2177
Mess. no.: F2177 (hex)
Supported by Firmware Variant:
According to scaling, the drive limits the actual position values to the
maximum travel range or to the modulo value. As these values possibly
cannot be exactly displayed the corresponding recalculation of the errors
takes place in the drive.
Remedy
Reduce encoder speed
- or –
change S-0-0103, Modulo value
