FAQ #100921

 

Counter function
Cou 1 = Add (adding impulses to preset value and reset to "0")
Cou 2 = Sub (subtracting pulses from preset value down and reset to preset value)
Cou 3 = AddAr (adding impulses to preset value and automatic reset to "0", fleeting-On contact by reaching the preset)
Cou 4 = SubAr (subtracting pulses from preset value down and automatic reset to preset value, leeting-On contact by reaching value "0")

In E1 = Mod 0 (INP A=count input, INP B= count direction input)
In E2 = Mod 1 (INP A=count input adding, INP B= count input subtracting)
In E3 = Mod 2 (INP A=count input 0°, INP B= count input 90°)
In E4 = Mod 5 (same as E3 but with pulse doubling. Each pulse edge of INPA will be counted)

Timer function
Time1 = add (permanent signal when count value >=preset value or timed signal when count value = preset value. reset to 0.)
Time2 = sub (Permanent signal when count value <=zero or timed signal when count value = 0. Reset to preset value.)
Time3 = addAr (Timed signal when count value = preset value and automatic reset to 0. Reset to 0.)
Time4 = subAr (Timed signal when count value = 0 and automatic reset to preset value. Reset to preset value.)

Freqeuncy function
In E1 = Mod 0 (Inp "A" counting, Inp "B" count-direction)
In E2 = Mod 1 (Inp "A" adding, Inp "B" subtracting)
In E3 = Mod 2 (phase-discriminator for incremental shaft encoder, Inp "A" 0°, Inp "B" 90° shifted)
In E4 = Mod 5 (similar Mode 2/E3 but with pulse doubling by counting each flank up and down)

Remarks
The product CXD will reach its end of life by the end of June 2008. Therefore it is not recommended using this product for new applications. The replacement product is CXQ 312.
