Stop Method At Stroke Limit Detection; Servo Parameter List - Mitsubishi Electric MR-J5 Series User Manual

When the movable range is not limited
On a system configuration without the limited movable range, such as a conveyor, set LSP/LSN to be automatically turned on.
As the signal is set to be always turned on, the servo motor does not stop with the stroke limit. This can be set from the "Basic
Setting" of "Digital I/O" on MR Configurator2.

Stop method at stroke limit detection

When LSP (Forward rotation stroke end)/LSN (Reverse rotation stroke end) is turned off, the servo motor stops in accordance
with the setting of "Stop method selection for when either the LSP (Forward rotation stroke end) or the LSN (Reverse rotation
stroke end) is off" in [Pr. PD30].
In MR Configurator2, a stop method can be selected in "I/O Setting".
Setting value of [Pr. PD30.0]
"0"
Quick stop (initial value)
"1"
Slow stop
When the stroke end is detected, perform the following return methods. If the home position is erased, perform homing.
