0: Ramp to stop
1: Coast to stop
This parameter determines how the motor is stopped when the GS4 drive receives a valid stop
command.

Ramp to stop: The GS4 drive decelerates by the time setting of Deceleration Time to 0 or Minimum
Output Frequency (P2.08) and will then stop. The ramp rate is set by Maximum Output Frequency
(P0.04) and the currently selected Deceleration Time (P1.02, P1.04, P1.06, or P1.08).
• Example 1: Maximum Frequency = 60Hz, Motor is running at 60Hz, and Deceleration Time is set
for 10s� The motor will ramp to stop in 10s� If the motor is running at 30Hz, the motor will ramp
to stop in 5s�
• Example 2: Maximum Frequency is set to 120Hz, the motor is running at 60Hz, and the Decel
Time is set for 10s� The motor will ramp to stop in 5s�
When stopping high inertia loads in ramp-to-stop method, it may be necessary to add a
braking resistor.
Coast to stop: The GS4 drive stops the output instantly upon a STOP command, and the motor
coasts to a complete stop.
• We recommend using "ramp to stop" for safety of personnel or to prevent material from being
wasted in applications where the motor has to stop after the drive is stopped� The deceleration
time has to be set accordingly�
• If the motor free running is allowed or the load inertia is large, we recommend to selecting "coast
to stop�" For example: blowers, punching machines, and pumps�
