■ Switch ON Termination Resistor for MEMOBUS/Modbus Communications
When the drive is the last slave in a MEMOBUS/Modbus communications, set DIP switch S2 to the ON position.
This drive has a built-in termination resistor for the RS-485 interface.

◆ Selecting the Control Method
This section gives information about these basic control methods:
• V/f Control (V/f)
• Open Loop Vector Control (OLV)
Set the most applicable control method for your application. A1-02 [Control Method Selection] sets the drive
operation.
Control Method A1-02 Main Applications
V/f 0
• General variable-speed. Best method to operate more than one motor from one drive.
• When motor parameters are not available.
OLV
2
(Default)
• General variable-speed
• High precision and high speed response without speed feedback
