Chapter 7 Built-in High-speed Counter Function
XBC E-Type Main Unit 7-2 Ver. 1
Classification
Description
“E” type
External
output
Output points
1 point/channel (for each channel)
:uses output contact point of main unit
Type

(included or excluded) (program setting)
Output type Relay, Open-collector output (Sink)
Count Enable Set through program (count available only in enable status)
Set through terminal (contact) or program
Auxiliary mode
(Program setting)
Count Latch
Count per unit time (time setting value: 1~60,000ms)
2. Counter/Preset input specification
Classification Spcification
Input voltage 24V DC (20.4V ~ 28.8V)
Input current 4㎃
ON threshold voltage (min.) >20.4V
OFF threshold voltage (max.) <6V
If higher pulse than high speed counter input limit is inputted, 「abnormal operation stop」 error
may occur because MPU processing time increases to count fast and memory becomes full.
When using high speed counter, consider this.
