Item OverviewPF Threshold Sets the PF (Power Fail) threshold value for the signal output.

The threshold value is applied to the CV reference value or the CC reference value according to the mode setting.The value can be set within the range of 50 [%] to 95 [%] of CV reference value or or CC reference value. (factory setting: 80%)

PF Mode Sets the operat ion mode to perform PF judgment.Click the display area to select the mode.CV PF : When the output voltage falls to the PF threshold, the PF signal is output .CC PF : When the output current becomes less than the PF threshold, the PF signal is output.Factory setting：CV PF

PF Count Set the time to check keeping PF state from when PF is detected untilwhen PF signal is actually output .Set ting the PF count prevents the PF signal from being erroneously output due to noise or the like.The value can be set in the range of 0 [x 1 ms] to 100 [x 1 ms]. (Factory setting: 0 count = 0 ms)

Auto Recovery Sets the recovery time of output when protection set for auto recovery is activated. 　If the protection factor continues to occur, the output is shut down again after the automatic recovery time has elapsed. 　At the same time, if protection set for latch stop is occurring, output will not be recovered even if the automatic recovery time elapses.

The value can be set in the range of 100 [x 10 ms] to 1000 [x 10 ms]. (Factory setting: 100 count = 1 sec)

· Example of PF set ting (24 V model)CV reference value : 0.85 (24 V x 0.85 = 20.4 V)PF Mode : CV PF PF Threshold : 80 %

PF threshold voltage = CV reference value x PF threshold = 20.4 V x 80 % = 16.32 V

5.3 Q formatQ format is a numerical type for handling decimal virtually with integer data.GXE treat all values as integers (Binary numbers).So GXE handles numeric values with Q format data when you need decimal values.In the Q format, when written as Q"n" format, data is handled assuming that there is a decimal point between the "n" th bit and the "n 1" th bit of the data.

Example ) 1.25 [Q10]1.25 [Q10] = 1.25 x 210 = 1280d = 0x0500 = 0b0000 0101 0000 0000 In the case of a signed integer,

"b15" is sign bit.20 + 22 = 1 + 0.25 = 1.25

The numerical resolution becomes 2n. Example) In Q10 format, 210=1/1024Therefore, for values that cannot be divided by 2n, it shall be an approximate value.For example, when decimal number is 0.1, decimal operation can be divided by first decimal place and value can be accurately expressed.However, because binary operation cannot divide the value, truncation errors occur even if the number of digits in the decimal part is increased.

Assuming that it is expressed in Q16 format [16 decimal places]0.1 [Q16] = 0.1 x 216 = 6553d = 0x1999 = 0b0001 1001 1001 1001

It becomes a circulating binary decimal of 1100 from the bit weight of 24.Returning the value of this binary number to decimal number, it will be 0.0999908447265625.(it will not be exact 0.1)Because it is a circular decimal, truncation errors do not disappear even if infinitely increasing the number of digits.

・When the numerical data is normalizedThe actual value is the reference value when the normalized data is 1.0.As the numerical value becomes a decimal number, GXE handles normalized data in Q format.

・Conversion of physical quantity (voltage and current) and normalized dataNormalized data = physical quantity / reference valuePhysical quantity = reference value x normalized data

・Example of output voltage measurement value of 24V modelReference value = Nominal voltage = 24 [V]When the output voltage = 23.5 [V]Normalized data = 23.5 / 24 = 0.97917Q format representation of normalized data

Q10 format: INT (normalized data * 210) = 1002d = 0x03EAQ14 Format: INT (normalized data * 214) = 16042d = 0x3EEA

Conversely, when converting the normalized data expressed in the Q format to the physical quantityPhysical quantity = reference value x Qn format data x 2 n
