Stop Method For Lsp (Forward Rotation Stroke End) Off Or Lsn (Reverse Rotation Stroke End) Off - Mitsubishi Electric MELSERVO-J4 Series Instruction Manual

7. PARAMETERS

7.5 Stop method for LSP (Forward rotation stroke end) off or LSN (Reverse rotation stroke end) off

Select a servo motor stop method for when LSP (Forward rotation stroke end) or LSN (Reverse rotation stroke
end) is off with the first digit of [Pr. PD30].
