Figure 5.2 Setting the Frequency Reference by Current Input
Setting 2: MEMOBUS/Modbus Communications
Using
this setting, the frequency reference can be entered via RS-422/485 serial communications using the MEMOBUS/
Modbus protocol by using an optional SI-485/J Interface for MEMOBUS communication. Refer to Peripheral Devices
& Options on page 147. For details about the MEMOBUS/Modbus protocol, Refer to MEMOBUS/Modbus
Communications on page 185.
Note: If the frequency reference source is set for MEMOBUS/Modbus but a communication interface option is not installed, an oPE05
Programming Error will be displayed on the digital operator and the RUN command will not be accepted.
Setting 3: Potentiometer Option
Using this setting, the frequency reference can be set by a potentiometer mounted at the drive using an AI-V3/J
Potentiometer option unit. Refer to Peripheral Devices & Options on page 147 and the option unit documentation.
Note: If the frequency reference source is set for the potentiometer option (b1-01 = 3) but an option board is not installed, an oPE05 Programming
Error will be displayed on the digital operator and the RUN command will not be accepted.
