Condition Selection Of Function Validity By Second Function Selection Signal (Rt) - Mitsubishi Electric FR-E700EX Instruction Manual

A PM motor is a magnet motor. High-voltage is generated at motor terminals while the motor is running. Do not
touch motor terminals and other parts until the motor stops to prevent an electric shock.
Parameter referred to
Pr.178 to Pr.184 (input terminal function selection)

4.12.3 Condition selection of function validity by second function selection signal (RT)

You can select the second function using the RT signal.
 When the RT signal turns ON, the second function becomes valid.
 For the RT signal, set "3" in any of Pr.178 to Pr.184 (input terminal function selection) to assign the function.
 The second function has the following applications.
(a)Switching between normal use and emergency use
(b)Switching between heavy load and light load
(c)Changing of acceleration/deceleration time by broken line acceleration/deceleration
