When the comparator value is under range, "- 99.999" is stored.
When the comparator value is invalid, "- 99.998" is stored.
When an error occurs, "+100.000" is stored.
*4 When reading data from a main unit in which the calculation function is set to 2-head
mode, the read range changes to "-999.99 - +999.99".
*5 This parameter can be used only when the detection mode of the sensor amplifier is peak-to-
peak hold. A reading error occurs when the mode is set to other than peak-to-peak hold.
This parameter may be used for judging the outer diameter of cylinders, in order to
read the peak and bottom values during measurement.
*6 When you use this parameter for an expansion unit, a reading error occurs.
*7 If the sensor amplifier is in error, the analog voltage output is +5.500 and the analog
current output is +03.00.
*8 If the number of edges is 100 or more, a value 99 is read.
*9 If a prohibited combination of functions is written, it results in "abnormal setting (1)". For
details of each function, refer to the IG Series User's Manual.
Example:
Settings are reconfigured to use the calculation function, whereas the measurement
mode is "pin interval judgment mode or pin diameter judgment mode".
*10 This item includes also the results of "initial reset request" and "system parameter
set request" motion commands.
*11 The command reads the execution result of the "zero shift execution request" or
"zero shift reset execution request" whichever was last issued.
*12 By reading the "system parameter current state," the system parameters of the sensor
amplifier can be checked. The system parameters are comprised of the settings of
"judgment output/edge check output" polarity and analog output.
The "system parameter" attribute specifies the system parameters which are set when
the "system parameter set request" is executed by a motion command.
The values to be read or written are specified by translating them to binaries and using
ON or OFF in each bit of the binaries.
Assume the read data is "006":
Translating "6" to a binary number gives "0110".
Thus, the sensor amplifier from which the data was read is set to "NPN
output" and "analog output 1 to 5 V".
