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)
• EZ Open Loop Vector Control (EZOLV) for induction motors only
Refer to the Technical Reference for information about speed feedback and Permanent Magnet/Synchronous
Reluctance motor control methods.
Set the most applicable control method for your application. A1-02 [Control Method Selection] sets the drive
operation.
