Setting the Acceleration Rate

NOTE The default setting for both acceleration and deceleration is maximum (MAX). If the MAX indicator

lights are already lit, no input is required. To choose a different setting, follow the steps below.

Maximum Deceleration Slow Deceleration Off

Full brake is used from set

speed to near 0 rpm, to

bring the rotor to a stop in

the shortest possible time.

Reduced brake is used

during the last few rpm

until 0 is reached, to

minimize disturbance of the

sample.

Reduced torque is used from set speed to

500 rpm, causing deceleration to 500 rpm to

take twice as long as maximum deceleration.

(The exact rate depends on the mass of the

rotor in use. Larger rotors will take longer.)

Deceleration time from 500 to 0 rpm is

approximately 2 minutes (larger rotors take

longer).

No brake is used. Rotor

coasts to 0 rpm. This

process can take up to

1 hour, depending on the

rotor in use and the speed

at the start of

deceleration.
