Chapter 4 High-speed Counters
Fetching counts from encoder
Uses the double (x2) multiplication mode to fetch phase differential input from the
encoder.
The fetched data is output as BCD data. Phase differential input: 0004, 0006 BCD
output: 0600 to 0615 (4 digits)
Cording
● Initial setting
Special utility relays
•
Turn ON 2013 to reset the current value of CTH0 when CTC0 turns ON.
• Turn ON 2113 and turn OFF 2114 to set the high-speed counter to double (x2)
multiplication mode.
• Turn ON 2400 to enable the external reset.
The counter is reset at the rising edge of input 0008.
Note : The external reset input 0008 is set with hardware. Programming is not
necessary except for setting the external reset enable relay (2400 to ON).
