Function Assignment Of External Terminal And Control; Input Terminal Function Selection (Pr. 178 To Pr. 189) - Mitsubishi Electric FR-B-750 to 75K Instruction Manual

Function assignment of external terminal and control

4.11 Function assignment of external terminal and control

Purpose
Assign function to input terminal
Set MRS signal (output shutoff) to
normally closed contact specification
Make the second (third) function
valid only during constant speed
operation
Assign start signal and forward/
reverse command to other signals
Assign function to output terminal
Detect output frequency
Detect output current
Remote output function
Detect output torque
