144 Actual signals and parameters
Terms and abbreviations
Fieldbus equivalent
Example: If parameter 2008 MAXIMUM FREQ (see page 191) is set from an external
control system, an integer value of 1 corresponds to 0.1 Hz. All the read and sent
values are limited to 16 bits (-32768…32767).
Actual signals in the short parameter view
Term Definition
Actual signal Signal measured or calculated by the drive. Can be monitored by the user.
No user setting possible. Group 01: Operating data…Group 04: Fault history
contain actual signals.
Def Parameter default value
E Refers to types 03E- with European parametrization
FbEq Fieldbus equivalent: The scaling between the value and the integer used in
serial communication.
Parameter A user-adjustable operation instruction of the drive. Group 10:
Start/Stop/Dir…Group 98: Options contain parameters.
Note: Parameter selections are shown on the Basic Control Panel as integer
values. For example, parameter 1001 EXT1 COMMANDS selection COMM
is shown as value 10 (which is equal to the fieldbus equivalent FbEq).
U Refers to types 03U- with US parametrization
Actual signals in the short parameter view
No. Name/Value Description FbEq
04 FAULT HISTORY Fault history (read-only). See Group 04: Fault history in the
list of all parameters.
0401 LAST FAULT Code of the latest fault. 1 = 1
