SETTING ACCELERATION AND DECELERATION RATES

1
During transient conditions, such as acceleration and deceleration, rotor temperature may be outside this range.
3-8
Result
After you release the knob, the display shows the selected tempera-
ture. After 5 seconds, the display reverts to the actual current chamber
temperature.
When the run begins, the display shows the rotor temperature ±2°C
(after a period of temperature equilibration).
NOTE
The system controls the chamber temperature to
within ±2°C of the set temperature.
temperature within ±1°C of set, perform the
temperature calibration procedure provided in
the Appendix.
Tables 3-1 and 3-2 describe the acceleration and deceleration settings.
Figure 3-1 provides a graphic representation of these settings.

To control
Slow Acceleration
Reduced torque is used from 0 to 500 rpm,
lasting approximately 2 minutes. (The time
varies depending on the mass of the rotor
in use. Larger rotors take longer.). Above
500 rpm, full torque is used until set speed is
reached.
