Stopper Control Function (Pr.512 To Pr.515, X29 Signal) - Mitsubishi Electric FR-E700EX Instruction Manual

Position control
4.5.6

Stopper control function (Pr.512 to Pr.515, X29 signal)

Under stopper control, the motor outputs holding torque to press a workpiece to a mechanical stopper for more
accurate positioning. This function enables a stable stop for positioning.

(1) Stopper control by the X29 signal (Pr.512 = "1", Pr.513, X29 signal)
 When the X29 signal (stopper control switchover signal) is assigned to the input terminal, the Pr.513 setting is applied and
E.OLT is disabled.
To input the X29 signal, set "29" in any of Pr.178 to Pr.184 (input terminal function selection) to assign the function to a
terminal.
 Stopper control by the X29 signal is compatible with both speed control or position control.
 When Pr.513 Stopper control torque limit has been activated and has stopped the motor, E.OLT does not occur, but the
electronic thermal O/L relay is activated. Thus, performing stopper control at a high load for a long time may cause the
motor overload trip fault (E.THM) or drive unit overload trip fault (E.THT).
 The Pr.513 setting must be 80% or lower to prevent the motor from overheating.
