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.
The dynamic brake is designed only for emergency
stopping. Design the system to stop within about
three minutes after the dynamic brake operates.
