RMC70/150 and RMCTools User Manual
Description
These parameters are used together with the Channel A Acceleration Offset and Channel
B Acceleration Offset parameters to calculate the Actual Acceleration from inputs 0 and 1
of a dual-input (differential) acceleration feedback.
After the Channel A Acceleration Offset is added to the Channel A voltage or current, it is
multiplied by the Acceleration A Scale to produce the Channel A Acceleration.
After the Channel B Acceleration Offset is added to the Channel B voltage or current, it is
multiplied by the Acceleration B Scale to produce the Channel B Acceleration.
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.

Description
These parameters are used together with the Channel A Acceleration Scale and Channel B
Acceleration Offset parameters to calculate the Actual Acceleration from inputs 0 and 1
of a dual-input (differential) acceleration axis. For each channel, the Acceleration Offset
shifts the voltage or current input as shown below:
