32-Bit High-Speed Addition/Subtraction Counter C235; D.4.7 Register Types - Delta VFD-E User Manual

Appendix D How to Use PLC Function|
Example:
LD X0
RST C0
LD X1
CNT C0 K5
LD C0
OUT Y0
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.

32-bit high-speed addition/subtraction counter C235:

1. Setting range of 32-bit high-speed addition/subtraction counter is :
K-2,147,483,648~K2,147,483,647.
2. The settings can be positive / negative numbers by using constant K or data register D
(special data register D1000~D1044 is not included). If using data register D, the setting
will occupy two continuous data register.
The total band width of high-speed counter that VFD-E supports is up to 30kHz and 500kHz for pulse
input.

D.4.7 Register Types

There are two types of register which sorts by characters in the following:
1. General
register
2. Special
register
D-26
: The data in register will be cleared to 0 when PLC switches from RUN
to STOP or power is off.
: Each special register has the special definition and purpose. It is used
to save system status, error messages, monitor state.
