Programming Reference

P.025 Stop Type

(continued)

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 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.

P.026 Function Loss Response

This parameter
specifies how the
drive will respond to
an open circuit
between terminal
strip inputs 16 and
20.

Parameter Range:

0 = Generate a fault (IET), and coast to rest
1 = Coast to rest without a fault

Default Setting:

0

Parameter Type:

Tunable

Refer also to parameters: P.013 Output Relay Configuration

If a function loss occurs, the motor will coast to rest. If P.026 = 0, a function loss
fault will be generated, and FL will be displayed.
