Delta Electronics VFD007CH23A-21 [476/638] Can be positive negative number the next number that counter counts up from 32 767 is
Chapter 16 PLC Function CH2000 Series
16-23
The setting of counter can use constant K or register D (not includes special data register
D1000~D1044) to be indirect setting.
If using constant K to be setting, it can only be positive number but if setting is data register D, it
can be positive/negative number. The next number that counter counts up from 32,767 is
-32,768.
Example:
LD X0
RST C0
LD X1
CNT C0 K5
LD C0
OUT Y0
X0
Y0
CNT C0 K5
X1
RST
C0
C0
1. When X0=On, RST command is executed,
C0 reset to 0 and output contact reset to
Off.
2. When X1 is from Off to On, counter will
count up (add 1).
3. When counter C0 attains settings K5, C0
contact is On and C0 = setting =K5. C0
won’t accept X1 trigger signal and C0
remains K5.
