Delta RMC151 - Manual (Page 913)

9 Register Reference
Default Value: 0
Description
This parameter is used on acceleration inputs together with the Acceleration Scale
parameter to convert the Voltage or Current of a single-input acceleration to an Actual
Acceleration. This parameter is used to shift the input voltage or current before they are
the volts scaled to acceleration units.
The Acceleration Scale and Acceleration Offset parameters apply only to acceleration
inputs. They are not used to calculate the derived Actual Acceleration on position or
velocity inputs.
Actual Acceleration = Acceleration Scale x ((Voltage or Current) + Acceleration
Offset)
See the Analog Acceleration Scaling topic for details on setting the Acceleration Offset.
Changing this Parameter
Because this parameter affects motion, the axis must be disabled or in Direct Output
before writing to this parameter. The Enabled and Direct Output Status Bits indicate these
states of the axis. When changing this parameter from RMCTools, the software will
automatically do this for you. This may cause a halt on the axis, which is expected.
