2.4. The details of the parameter setting
[F830: MODBUS continuous address]
VF-AS3 does not have parameters of the communication number “0xXXXA” to “0xXXXF” and “0xXXAX” to
“0xXXFX”.
When parameters are accessed with the Modbus function command 0x03 and 0x10, it is possible to select
these parameters are slipped or not by parameter [F830].
・[F830] = “0: Disabled” (Default setting)
Communication number “0xXXXA” to “0xXXXF” and “0xXXAX” to “0xXXFX” are skipped.
Example: When 3 word read/write command is executed from communication number “0x0009” ([ACC:
Acceleration time 1]), access the communication number in the following order.
Access word

2
[DEC: Deceleration time 1]
0x0010
3
[FH: Maximum frequency]
0x0011
・[F830] = “1: Enabled”
Communication number “0xXXXA” to “0xXXXF” and “0xXXAX” to “0xXXFX” are not skipped.
Example: When 3 word read/write command is executed from communication number “0x0009” ([ACC:
Acceleration time 1]), access the communication number in the following order.

Note) If the parameter not assigned is accessed (read) by communication, inverter returns "0x8000".
If the parameter not assigned is accessed (write) by communication, inverter returns error code
“0x02: Illegal Data Address”.

E6582125

[F897: Parameter writing]
When [F897: Parameter writing] is set to "1", all writing via communication is only done to the RAM. This
parameter can be used when frequently writing to EEPROM supported parameters, but the content of the
parameters return to the values stored in EEPROM each time the inverter is reset.
If you want to temporarily allow storage to EEPROM when [F897] = "1", you can set [FA93] to "1:
Temporarily suppress mode for RAM" to allow writing EEPROM supported parameters.
Important
▼The [F897] setting is reflected after a reset operation such as power off, so you need power
reset after the setting. In addition, note that if [0897] = "0" is set via communication, the
[F897] parameter does not return to "0: Storage to memory device". To set to "0", modify the
setting from the operation panel.

Embedded Ethernet Inverter to inverter communication [C680] to [C682]
[C680: EmbEth. Inverter to inverter communication select]
Adjustment range:
0: Disabled
1: Inverter to inverter communication
2: Pump control
[C681: EmbEth. Inverter to inverter communication ID]
Adjustment range:
0: Leader
1 to 9: Follower 1 to 9
[C682: Emb Eth. Inverter to inverter communication]
Adjustment range:
0: Follower (0Hz command when Leader fails)
1: Follower (continue running when Leader fails)
2: Follower (emergency off when Leader fails)
3: Leader (transmit frequency command)
4: Leader (transmit output frequency signal)
5: Leader (transmit torque command)
6: Leader (transmit output torque command)
When [C680] is set to “1: Inverter to inverter communication”, you can use inverter to inverter
communication. (Please refer to “Pump control function manual” E6582124 for usage of “2: Pump control”)
Inverter to inverter communication can be used to implement speed-proportional control between multiple
inverters without using a PLC or a computer. Commands are input to the leader inverter via the operation
panel or analog signal.
When the inverter-to-inverter communication function is used, the leader inverter keeps sending data
selected by parameter [C682] to all follower inverters on the same network. You can configure a network
using this function to perform simple synchronized operation or speed proportional operation.
* When the leader trips, all follower inverters operate according to the parameter [C682] of each follower
inverter.
* To select how the followers operate when cable is disconnected or the leader is turned off (continue /
alarm/trip), use the communication error detection function ([C606] to [C609]).
* Up to 9 followers can be connected by this function.

Important
▼In case of communication cable is disconnected, you can trip a follower inverter by using the
communication error detection function ([C606] to [C609]). The leader will not trip even if its
cable is disconnected. To trip the leader, install an interlock from the follower side using an
FL failure relay signal, etc.
Transmission data
The leader side operation command (Run/Stop and Forward/Reverse) and reference value (frequency
command, torque command, output frequency or output torque) are transmitted to the follower side.
These data are sent as UDP packets.
When transmitting frequency command or output frequency, data is converted using [FH: Maximum
frequency] as below.
Details of transmitted data during inverter-to-inverter communication (frequency value)
𝑓𝑐(%) = Leader frequency value(Hz) ×10000
Leader maximum frequency(Hz)(1=0.01%)
* Calculation results of 1 (0.01%) or less are rounded down. As a result, a maximum error of 0.01%
occurs.
Conversion details of frequency commands after they are received by followers
The value after conversion below is written to the RAM as a frequency command value.
𝑓𝑐(𝐻𝑧) = Reception data(%) × Follower maximum frequency(Hz)
10000 (1=0.01Hz)
* Calculation results of 1 (0.01 Hz) or less are rounded down. As a result, a maximum error of 0.01 Hz
occurs.
Parameter setting
Network setting
Please set the parameter [C610] to [C620] so that leader and followers build a single subnetwork.
Example settings
Leader
IP address: 192.168.0.10
Subnet musk: 255.255.255.0
Follower 1
IP address: 192.168.0.20
Subnet musk: 255.255.255.0
Follower 2
IP address: 192.168.0.30
Subnet musk: 255.255.255.0

Inverter to inverter communication setting
Set only one inverter on the network as leader and all others as followers.
* If multiple leaders are set on the same network, data conflict will occur. Be sure to only set one
leader.
Setting for the leader inverter
Set the data to be set from the leader to the followers.
3: Leader (transmit frequency command)
4: Leader (transmit output frequency signal)
5: Leader (transmit torque command)
6: Leader (transmit output torque command)
Setting for the follower inverters
Set the operation of the follower side when the leader trips.
0: Follower (0 Hz command when Leader fails)
Output frequency is limited by the lower limit frequency.
1: Follower (continue running when Leader fails)
When an output frequency is set on the leader, the trip causes the output frequency of the
leader to change to 0 Hz. In this case, the frequency command to the followers will be 0 Hz.
2: Follower (emergency off when Leader fails)
The stop pattern follows the [F603: Emergency off stop pattern] settings.
* These parameters are reflected after resetting the inverter or turning the inverter power off and then on.
Run command select ([CMOD]) and Frequency command select 1 ([FMOd])
For [CMOD] and [FMOd], set the input that gives commands to the inverter.
Setting for the leader inverter
Set an arbitrary value to receive the command for leader.
Setting for the follower inverters
Set a value for Embedded Ethernet ([CMOD] = "2", [FMOd] = "20").
