(3) Stopping method when the forward stroke end (LSP) or reverse stroke end (LSN) is valid
The setting of the first digit of parameter No.PD20 enables to select a stopping method of the servo motor
when the forward rotation stroke end (LSP) or reverse rotation stroke end (LSN) turns off.
Stopping method when the forward rotation stroke end (LSP) or
reverse rotation stroke end (LSN) is valid
0: Sudden stop (home position erased)
1: Slow stop (home position erased)
2: Slow stop (Setting contents is the same as for “1”.)
