*FPV = Field power supply voltage
(1)
Time between successive SSI words (Tp). Also called Dwell Time.
(2)
Roughly corresponds to the maximum time the SSI sensor can be expected to output a particular position value while in
motion. To use the 1734-SSI module with sensors that have faster position forming times, change the SSI Word Filter
Control parameter from its default value of 5 (max). Changing this parameter from its default value sacrifices electrical
noise environment performance for sensor data conversion speed.
