P.025 STOP Type
Parameter Range: 0 = Coast to rest stop
1 = Ramp to rest stop
Initial Setting: 0

Refer to: P.002 Decel Time 1
P.018 Decel Time 2
P.022 Jog Ramp Decel Time
U.000 Torque Reference Source
WARNING
The user must provide an external, hardwired emergency stop circuit outside the controller circuitry.
This circuit must disable the system in case of improper operation. Uncontrolled machine operation
may result if this procedure is not followed. Failure to observe this precaution could result in bodily
injury.
Description: A function loss or a fault will always cause a coast-to-rest stop.
If the drive is configured as a torque regulator (U.000 > 0 and TRQ/SPD digital input = TRQ),
then the stop type will always be coast-to-rest regardless of the value in parameter P.025.
If RUN is selected:
If P.025 = 0 , pressing the STOP/RESET key or giving an external stop command will cause the
motor to coast to rest.
If P.025 = 1 , pressing the STOP/RESET key or giving an external stop command will cause the
motor to ramp to rest within a time equal to or greater than the preset deceleration time
(P.002/P.018).
If JOG is selected:
Pressing the STOP/RESET key or giving an external stop command when JOG is selected will
stop the motor differently depending on whether the drive is configured for V/Hz or vector
regulation:
For V/Hz regulation, the motor will always perform a ramp stop regardless of the value in P.025.
For vector regulation, the motor will stop based on the value of P.025:
•
If P.025 = 0 , pressing the STOP/RESET key or giving an external stop command will cause
the motor to coast to rest.
•
If P.025 = 1 , pressing the STOP/RESET key or giving an external stop command will cause
the motor to ramp to rest within a time equal to or greater than the preset deceleration time
(P.022).
Note that when the START input from the selected control source is released (unasserted),
the motor will ramp down in speed regardless of the value in P.025
