(1) Transmission format selection
In the [Summary Specifications] list box, select the transmission format of FRENIC-VG. For the
detailed specifications of each transmission format, refer to the function code U11 "SX transmission
format selection".
Standard format 1 and 2 ⇒ VG7: FRN VG7(S)
(for the latest version,
VG1/VG7 (STD1): FRENIC-VG (S1))
UPAC compatible format ⇒ VG7S/UPAC: FRN VG7 (U)
(for the latest version,
VG1/VG7 (UPAC): FRENIC-VG (U))
Monitoring format ⇒ VG7S/MONITOR: FRN VG7 (M)
(for the latest version,
VG1/VG7 (MONITOR): FRENIC-VG (M))
Note: Be sure to select the same format as the function code U11. If the settings are different, the
heavy alarm "Device configuration error" occurs and communication will not be available.
(2) I/O group setting
Allocate the module (inverter) in the MICREX-SX CPU. Incorrect allocation of the I/O group
disables input/output control from the CPU.
Right-click the CPU on the system configuration definition tree, and select [Properties] to open the
[Module Properties] dialog box.
Click the parameter and the [I/O Group Setting] tab to open the [I/O Group Setting] dialog box.
Note: In a multi-processor system, if an individual CPU module has a different control target,
configure the I/O group for an individual CPU.
