Sets the deceleration stop operation to be performed after the Forward Drive Prohibit Input (POT) or
Reverse Drive Prohibit Input (NOT) is enabled.
Note1. The positioning command generation process (positioning operation) within the Servo Drive
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.
Note2. When the Servomotor rotation speed is 30 r/min or less (stopped), the deceleration mode
will not be activated even if the drive prohibit input is enabled.
Note3. When the parameter is set to 2 and an operation command in the drive prohibited direction
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.
Note4. When the parameter is set to 2, MECHATROLINK-II communications are interrupted, and
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.
Note5. With a vertical axis, there is a risk that the load may drop when drive is prohibited by the
drive prohibit input. To prevent this, it is recommended that the deceleration method be set
to use emergency stop torque in the Drive Prohibit Input Stop Selection parameter (Pn066),
and that stopping in the servo-lock state be set (set value: 2).
