• [GPI Lock]
GPI Lock can be turned on or off via GPI input. When GPI Lock is ON, all GPI inputs other than
the one being used for GPI Lock control are locked and input will be ignored.
[Parameter], [Min], and [Max] are not available.
[Terminal] determines how the GPI input voltage will affect the specified parameter.
GPI lock will be ON when the voltage applied to GPI IN is above the median voltage*, and
OFF when the voltage is below the median.
GPI Lock will be OFF when the voltage applied to GPI IN is above the median voltage*, and
ON when the voltage is below the median.
GPI Lock will be alternately turned ON and OFF each time the voltage applied to GPI IN drops
from below to above the median voltage.*
GPI Lock will be alternately turned ON and OFF each time the voltage applied to GPI IN rises
from above to below the median voltage.*
