 Acceleration/deceleration time setting
• Set the acceleration/deceleration time for parameters corresponding to each point table.
• The frequency which is the basis of acceleration/deceleration time is Pr.20 Acceleration/deceleration reference
frequency. However, 1 Hz/s is the minimum acceleration/deceleration rate (acceleration/deceleration frequency divided
by acceleration/deceleration time). If the acceleration/deceleration rate is smaller than 1, the motor runs at 1 Hz/s or in the
deceleration time.
• The maximum acceleration/deceleration time is limited at 360 seconds.
• During position control, acceleration/deceleration pattern is always the liner acceleration/deceleration. The settings of
Pr.29 Acceleration/deceleration pattern selection, Pr.791 Acceleration time in low-speed range, and Pr.792
Deceleration time in low-speed range are ignored.
• This setting is applied to the operation also when the RT signal input or the motor speed is equal to or higher than the
Pr.147 Acceleration/deceleration time switching frequency. (The second deceleration time is ignored.)
 Auxiliary function setting
• Set the handling and operation methods of the position data in each point table, using Pr.1225, Pr.1229, Pr.1233, Pr.1237,
Pr.1241, Pr.1245, and Pr.1249.
• Set the auxiliary function for parameters corresponding to each point table.

• For the sign, select the sign of position data.
• For the command method, select the absolute position command or incremental position command. For the absolute
position command, specify the distance from the home position. For the incremental position command, specify the
distance from the current position command.
• When performing position control, always perform the home position return. Position commands cannot be received until
the completion of the home position return. The home position return is not required when the roll feed mode (Pr.1293 =
"1 or 2") is selected. For the home position return, refer to
• For the operation method, select individual or continuous. When continuous operation is selected, next point table is
executed after a command has been executed.
• Continuous operation cannot be selected for the point table 7. ("10, 100, or 110" can be set in Pr.1249).
• Individual operation is only executed in the selected point table.
• When the incremental position command is selected and the STR signal is used as a start signal, the sign of position data
is reversed. When the absolute position command is used, the sign of position data is not reversed even if the STR signal
is used as a start signal.
