F.7 Units
The drive parameters are in engineering units. Based on the value of the UNITS parameter, the values
are either interpreted as METRIC (0) or ENGLISH (1). Hence parameters written over the fieldbus must
be written in the correct units.
F.8 PARAM_UPDATE_in
Parameters that pertain to the actuator performance, geometry and motion will not take effect on the
drive unless the PARAM_UPDATE_in parameter is set to 1 and the drive is disabled and the drive is
not faulted. This is a safety precaution to avoid unexpected actuator movement. The
PARAM_UPDATE_in parameter will auto-reset to 0 after the drive has recalculated parameters.
F.9 Implicit I/O
The following parameters are available for Implicit I/O exchange. The parameters take up a total of 16
bytes for input and 16 bytes for output of Polled I/O. See the Parameter List table on the following
pages for further detail on the parameters.
