Sets the deceleration stop operation to be performed after the Forward Drive Prohibit Input (POT) or
Reverse Drive Prohibit Input (NOT) is enabled.

Pn No.
Pn067
Sets the operational conditions during deceleration and after stopping after the main power supply is
turned OFF with the Undervoltage Alarm Selection (Pn065) set to 0.
The deviation counter will be reset when the power OFF is detected.

will be forcibly stopped once it enters the deceleration mode. Also, when the deceleration
mode is activated during speed control or torque control, it will switch to position control. If
a positioning operation command is received during deceleration, the internal positioning
command generation process will be retained, and after deceleration is complete,
positioning operation will be activated.
will not be activated even if the drive prohibit input is enabled.
is received after stopping, a command warning (warning code 95h) will be issued. When the
parameter is set to 0 or 1, the operation command in the prohibited direction after stopping
will be accepted, but the Servomotor will not operate and the position deviation will
accumulate because the torque command is 0. Take measures such as issuing a command
in the reverse direction from the host controller.
either Forward or Reverse Drive Prohibit Input (POT or NOT) is turned ON, receiving an
operation command (jog operation or normal mode autotuning) via RS232 will cause a Drive
Prohibit Input Error (alarm code 38). A Drive Prohibit Input Error (alarm code 38) will also
occur if either POT or NOT is turned ON while operating on an operation command received
via RS232.

0 and 4 Use dynamic brake to decelerate and remain stopped with dynamic brake.
1 and 5 Use free-run to decelerate and remain stopped with dynamic brake.
2 and 6 Use dynamic brake to decelerate, but free the motor when stopped.
3 and 7 Use free-run to decelerate, and free the motor when stopped.
