Instance Services

Service Code Service Name Description of Service

0x0E Get_Attribute_Single Read one attribute

0x10 Set_Attribute_Single Write one attribute

Attribute ID of all parameters are 3. Moreover, about the instance ID of each parameter, it

becomes "parameter communication number + 4000Ｈ".

In the case of the parameter from which a communication number begins in "F", it

becomes "parameter communication number - 0x8000 (same as bit15 set to 0)".

About the detail contents of a parameter, please refer to a VF-MB1 or VF-S15

instructions manual.

Example 1:

In case of Basic parameter “cmod - Command mode selection”,

Communication No: 0003 -> Instance ID: 4003

Example 2:

In case of Extended parameter “f268 - Updown frequency default value”,

Communication No: 0268 -> Instance ID: 4268

Example 3:

In case of Monitor parameter “fe03 - Output current”,

Communication No: FE03 -> Instance ID: 7E03

* Monitor parameter can access "Get" only.

For example, when "Acc. time" is set to 5 sec., since the minimum unit is 0.1s,

5 / 0.1 = 50 = 32H

Since the communication number of "Acc. time" is "0009", it writes "32H" in instance ID

"4009."

Moreover, when the "highest frequency" is read, "1F40H" is read.

0x1F40 = 8000 (Dec.)

Since the minimum unit is 0.01Hz,

8000 * 0.01 = 80Hz
