RMC70/150 and RMCTools User Manual

This bit is set when the Target Pressure/Force and the Actual Pressure/Force are at th

Command Pressure/Force. This is defined as when the Pressure/Force Error is less tha

the At Pressure/Force Tolerance. The axis must be in closed-loop pressure/force

control or pressure/force limit and the Pressure/Force Target Generator Done bit mus

be set.

20 PFInputEst

Pressure/Force Input Estimated

If a Pressure/Force No Transducer or Pressure/Force Transducer Overflow condition

exists, the Pressure/Force Input Estimated bit will turn on to indicate an error conditio

exists and the feedback value is being estimated. If the error condition occurs for

successive 3 loop times, the associated Pressure/Force No Transducer or

Pressure/Force Transducer Overflow error bit will be set.
The Pressure/Force Input Estimated bit is set as long as the error condition exists,

even after the error bit is set following the first 3 loop times.
"Estimated" means that the feedback value is not accurate. It does not necessarily

mean that it is being estimated to a high degree of certainty.
The Pressure/Force Input Estimated bit is not set if a Pressure/Force Noise Error

condition exists. A Pressure/Force Noise Error condition will immediately set the

Pressure/Force Noise Error bit.

21 PFTGDone

Pressure/Force Target Generator Done

This bit is set when the Pressure/Force Target Generator has completed its course, th

is, when a pressure or force ramp has been completed. If the ramp is interrupted, e.g

due to a halt, the done bit will not be set because the ramp was not completed.

22 PFTGStateA

Pressure/Force Target Generator State A

This bit is set to indicate the current state of the Pressure/Force Target Generator.

23 PFTGStateB

Pressure/Force Target Generator State B

This bit is set to indicate the current state of the Pressure/Force Target Generator.

24 TGSIBusy

Primary Target Generator Superimposed Busy

This bit is set to indicate that a superimposed move is in progress. This can be caused

by a Transition.

25 PFTGSIBusy

Pressure/Force Target Generator Superimposed Busy

This bit is set to indicate that a superimposed move is in progress. This can be caused

by a pressure/force transition.

26 FeedbackOK

Primary Axis Feedback OK

This bit indicates that the feedback transducer on the primary input has no errors. Th

bit provides the instantaneous general status of the transducer, and is especially usef

when implementing Custom Feedback. This bit is available in firmware 3.54.0 and

newer.
The Transducer OK bit will be off if the transducer is experiencing any of the following

No Transducer

Transducer Overflow

Transducer Noise (only for position axes)

Notice that the Transducer OK bit is instantaneous. The No Transducer, Transducer

Overflow, and Transducer Noise axis error bits do not necessarily provide the

instantaneous state of the feedback as the Transducer OK status bit does. These thre

error bits will turn on only after the error has existed for three loop times, during whi

time the Input Estimated bit is on. In addition, they will latch on and remain on even

the underlying error has gone away.
