Encoder and Temposonics Calibration
Encoders
Linear encoders measure the position change of the actuator’s piston rod by
digitizing, sensing, and resolving actuator movement.
Temposonics
transducers
MTS Temposonics™ linear displacement sensors measure the position change of
the actuator’s piston rod by sensing the position an attached permanent magnet.
The calibration procedure for both types of devices are similar.
Daughter board
support
For FlexTest SE/LE, FlexTest GT, and TestStar IIm, encoders and Temposonics
sensors require a Model 493.47 Encoder Interface daughter board to be installed
in a Model 493.40 Carrier I/O board. The Carrier I/O connector (J4 - J7) used
depends on the installed location of the daughter board on the Carrier I/O
module.
For FlexTest IIm/CTC, encoders and Temposonics sensors require an optional
daughter board installed in the 498 ADDA plug-in module.
Determine installed
location
For Automated Controllers, determine the installed location of the sensor’s
daughter board by using the Hardware tab on the Station Signals window.
Access Station Signals on the Station Setup window navigation pane.
For Standalone FlexTest SE Controllers, use the Edit > Config menu to do the
same.
For encoders, feedback resources labeled “Encoder Input #” or “Heidenhain 417/
425 Input #” indicate that the controller is equipped with an optional encoder
interface daughter board.
For Temposonics sensors, feedback resources labeled “Temposonics Input#” or
“Temposonics III Input #” indicate that the controller is equipped with an
optional Temposonics interface daughter board.
Zeroing For Automated Controllers, the sensor signal is defined in the Station Setup
Inputs panel.
For Standalone FlexTest SE Controllers, the encoder signal is defined in the Edit
> Config menu.
Note You cannot zero an encoder or Temposonics sensor if it is selected for
the active control mode.
Range support Encoder and Temposonics sensors do not support multiple ranges.
