Simultaneous Broadcast Registers (Write only)
Simultaneous Broadcast Registers are those registers used to control the simultaneous operation of multiple devices either through a
network interface (option card) or via serial communications. These registers are available during drive RUN.
The “Addr” column contains the register address in hexadecimal format. Drive registers are always referenced in hexadecimal format. The
“Function” column contains the register name. The “Bit” and “Description” columns contain the list of available bits for that register and a
short description of each. If the “Bit” column is empty, the register contains word data and individual bits are meaningless.

0002h Frequency Reference 30000/100 %**
Note: * Use of these bits is dependent on the setting of register 0Fh bits 0Ch, 0Dh, 0Eh and 0Fh. Refer to Table 4.1 – Command Registers (Read / Write).
** This value must be sent to the drive as a hexadecimal value. Example: 4096 = 1000h.
The scaling is fixed at 30000/100 %. and is not affected by parameter o1-03.
It is affected by the maximum frequency of the drive receiving the command. Simply it is ((decimal freq ref)/30000)* (drive’s maximum frequency).
Example: Send 1000h to drive. 1000h = 4096 decimal.
(4096*100 %)/30000 = 13.65 %.
If drive’s maximum frequency is 60 Hz, then the frequency reference command to the drive is 60*13.65 % or 8.19 Hz.
