Stop Method At Stroke Limit Detection; Servo Parameter List - Mitsubishi Electric MELSERVO-J5 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 [Pr. PD30.0 Stop processing selection at LSP/LSN signal off].
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.
Control mode
Position control mode
Speed control mode

Servo parameter list

The settings related to the stroke limit function can be performed directly with the servo parameters. Perform the settings as
required. For pin number of the input device pins and the corresponding servo parameters, refer to the following.

[AL. 099 Stroke limit Enable or disable [AL. 099 Stroke limit warning].
warning] selection When "Disabled" is selected, [AL. 099 Stroke limit warning] does not occur when LSP
(Forward rotation stroke end) or LSN (Reverse rotation stroke end) is off, but the stroke
limit does still stop the operation.
0: Enabled (initial value)
1: Disabled
Input signal Set LSP (Forward rotation stroke end) and LSN (Reverse rotation stroke end) to
automatic ON "Disabled" (use for an external input signal) or "Enabled" (Automatic on).
selection Initial value: 0h (disabled (use for an external input signal.))

Assign LSN or LSP to the specified pin in CN3.
In the initial setting, LSP is assigned to the CN3-43 pin, and LSN is assigned to the
CN3-44 pin.
At Stop processing Select the stop method at the stroke limit signal detection.
selection at LSP/LSN 0: Quick stop (initial value)
signal off 1: Slow stop
Magnetic pole Select whether to enable or disable the stroke limit function during magnetic pole
detection - Stroke detection.
limit enabled/disabled 0: Enabled (initial value)
selection 1: Disabled
