G.1 Glossary
Clockwise
Rotating in the direction of increasing encoder or transducer counts.
Closed Loop Mode
Sometimes called Servo mode. In this mode the difference between the Target and Actual
position/pressure is the error that the PID routine uses to compute a corrective drive that
minimizes the error.
Counter-Clockwise
Rotating in the direction of decreasing encoder or transducer counts.
Extending
Going in the direction of increasing encoder or transducer counts.
GSD file
This is a device description file required by every PROFIBUS device. The RMC’s GSD file is
installed with RMCWin’s program files. Refer to PROFIBUS Configuration for details on using this
file.
Hard Stop
An emergency stop condition where the drive is immediately set to the null drive value.
LDT
Linear Displacement Transducer. Technically, this is any sensor that can sense a linear position.
Many use this term interchangeably with MDT.
