Roll feed mode (Pr.537 = "1")
The current position and position command are set to 0 at start, and then position control is performed.
Because the current position and position command are set to 0 at start, position commands are not overflowed and the
repeated feed by the increment is available.
With this setting, no home position return is required.
The following shows an operation example with the parameter setting shown in the table below.

The start command must remain ON for 20 ms or longer.
Wait for 5 ms or longer after the table selection signal is turned ON. Then, turn ON the start signal.
