Ramp to stop: the brushless DC decelerates the motor to Minimum Output Frequency

Pr.01-09 and stops according to the deceleration time set in Pr.01-07.

Coast to stop: the brushless DC drive stops output instantly upon command, and motor free

run until it comes to a complete stop.

If the machinery is turned off, the motor must also be stopped to avoid waste of power and

for safety concern. It is suggested to set the brake ramp to stop with ramping duration

matches machinery characteristics.

As the machinery is turned off, if it is allowed for motor to spin freely or the inertia load is large,

it is suggested to set the motor to coast to stop.
