6 Parameter Description
 Hope800's counter can conduct high-speed UP/DOWN counting, with the highest frequency reaching
300kH if an encoder interface is adopted, 50kHz if a PFI terminal is adopted and 500Hz if a common
terminal is used.
The value in the counter can be stored after power-off and is used as the initial value for the next
counting.
Digital inputs 50 and 51 can preset or clear the counter. For the function of the counter, see the following
diagram.
Digital outputs 0~73
Digital outputs 0~73
Digital input 50
Digital input 51
Note: In quadrature counting mode (Fd-19=1), encoder channels A and B are fixed as the UP and DOWN
command channels.
F9-11, F9-12:
 When digital outputs 34~36 are selected, the input signal is affected by F4-11;
 Selecting the digital outputs 57 and 58 can realize high-speed counting, with the highest input
frequency reaching 300kHz;
 Selecting the digital output 59 can also realize high-speed counting, with the highest input
frequency reaching 50kHz;
 When other digital outputs are selected, the sampling time is 1ms.
F9-13 is used for calculation of FU-34 and for presetting the counter when the digital input 50 is valid.
When the count reaches F9-14, the digital output 31 becomes valid, and when the next UP count pulse
arrives, the digital output 31 becomes invalid.
When the count reaches F9-15, the digital output 32 becomes valid, and when the pulse number reaches
F9-14+1, the digital output 32 becomes invalid.
Example: If F9-11=34(X1), F9-14=9, F9-15=4, and Fd-20=6, then the digital outputs 32, 69 and 31
become valid when the input pulse number of X1 reaches 4, 6 and 9 respectively. When the next pulse arrives,
digital output 31, 32 and 69 becomes invalid simultaneously. Refer to the following diagram.
