KEYENCE KV Series User Manual

● Interrupt function
The Visual KV Series is equipped with four high-speed interrupt inputs of
10 µs maximum.
● Input time constant change function
The time constant can be set in 7 steps from 10 µs to 10 ms.
● Double memory backup functions
In addition to a conventional SRAM battery backup function, the Visual KV Series
is also equipped with an EEPROM backup function.
Compatibility with Conventional KV Series Peripheral Units
The Visual KV Series functions as a high-end compatible model of the conventional
KV Series. Peripheral units of the conventional KV Series such as the ladder support
software "KV IncrediWare (DOS)" and "LADDER BUILDER for KV" and the
handheld programmer KV-P3E(01) can be used since they are part of the Visual KV
Series.
However, it should be noted that the contents have changed as follows.
•
The internal clock cycle of high-speed counters consists of three types: 1 µs, 10
µs, and 100 µs.
•
The time constant for an input relay specified by the HSP instruction is 10 µs.
•
The analog trimmer function is set with the Access Window built into the basic
unit.
•
The available device setting range of the TMIN instruction is from 0 to 65535.
[Handheld programmer KV-P3E(01) can display 0 to 9999 .]
•
The RUN/PROGRAM LED is displayed in the Access Window provided on the
front face of the basic unit.
•
Transistor output is not independent, but is common.
•
With the transistor type, the output terminal layout is different.
•
The specifications for output current of transistor outputs Nos. 500 to 502 is 100
mA.
•
Conventional KV Series expansion units are not available as expansion units for
the Visual KV Series.
•
The channel setting switch is not provided for expansion units. Channels are
determined in connection order.
•
Scans in expansion I/O units are not synchronous with the scan time in Visual KV
Series basic units.
•
Assignment of special utility relays has partially changed.
•
Data memory device Nos. DM1000 to DM1999 are assigned as special data
memories.
