Data Type: REAL
Units: Pr or Fr
Range: any
Default Value: 0
Description
The Pressure Offset or Force Offset parameter is used together with the Pressure Scale or
Force Scale parameter to calculate the Actual Force or Actual Pressure from the voltage or
current of the input.
The Offset is added to the scaled Pressure or Force.
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
Each RMC axis allows for optional physical limit inputs to specify the boundaries in which
the axis is allowed to operate. Each axis can have two physical limit inputs: Positive Limit
Input and Negative Limit Input. Typically, these inputs are wired to limit switches.
The physical limit inputs differ from the Travel Limits, which limit the range of travel of an
axis based on the feedback (position, pressure, etc.). The Travel Limits are required to be
set on an axis; physical limit inputs are optional.
The Positive Limit Input bit parameter selects which discrete input, if any, should be used
as a 'Positive Limit Input'. For details on the operation of the physical limit inputs, see the
Physical Limit Inputs topic.
In RMCTools, this parameter will allow you choose an input from the drop-down box.
Inputs will be listed by their address. Use the Discrete I/O Configuration editor to find the
addresses of inputs.
