Introduction
Thank you for purchasing a “CC-Link Option (CCL001Z)” for TOSVERT VF-AS1 inverter.
This option can connect with open field network CC-Link and data communications with the
CC-Link master through installing this option in the VF-AS1 and using it. Besides this
instruction manual, the "CC-Link option Instruction Manual" is required to develop software
communicating with VF-AS1. In such a case, please get in touch with our branch offices or
sales offices. ("CC-Link Option Instruction Manual": E6581286).

NOTICE
▼See the instruction manual of "TOSVERT VF-AS1 CC-Link Option
Instruction Manual" (E6581286) for cautions relating to the ambient
environment, installation and wiring.
▼Turn off the power supply when connecting or disconnecting a
communication cable.
▼When the control power is turn off by the instantaneous power failure,
communication will be unavailable for a while.
▼The Life of EEPROM is approximately ten thousand times.
Avoid writing a command more than ten thousand times to the same
parameter of the inverter.

1.Set the Station No.
Set the inverter station number before switching on the inverter and do not change the
setting while power is on.
The station number can be set between 1 and 64.
The switch x10 is set up the ten's place and x1 is set up the ones.
Set the arrow (↑) of the corresponding switch to the required numeral.
*The station number changed while powering on the inverter is not made valid.
*Set the station numbers consecutively in a connection sequence.
(The station numbers may be also set independently of the connection sequence.)
*Note that the same station number cannot be regarded.
(If the same station number is repeated, proper communication cannot be made.)
*Set each station number switch to the position of its numeral securely. If it set to any
position between numerals, normal data communication cannot be made.

Divide the monitor code (RWw n) into half and select the first monitor description (RWr n)
from the lower 8 bits and the second monitor description (RWr n) from the higher 8 bits.
(Example) When output voltage is selected for the first monitor and output torque is
selected for the second monitor. -> The monitor code is 0703H.
* The hexadecimal value attaches and expresses "H" to the end of a number.

RWw signal
Address Signal name Description
RWw n Monitor code
Sets the monitor code to be referenced. By switching on the (RYnC) signal after
setting, the specified monitored data is set to (RWrn).

Specifies the set torque. After setting the register, a torque is written after turning
on the RYnE. When the writing of the torque is completed, RXnE turns on,
depending on the input command.
RWw (n+2) Command
code
Sets the command code for actions such as operation mode switching, parameter
read, write, error reference, error clear, etc. The command will be executed by
turning RYnF on after the register setting is completed. When the command
execution is completed, RXnF turns on.
RWw (n+3) Write data
Sets data specified by the above-mentioned command code (if necessary).
If no data needs to be written, the value shall be zero.
RYnF is turned on after setting the above-mentioned command code and this
register.
