Signal Description
START/STOP: input signal to start or stop the pump. Without the supplied cover
connector the turbomolecular pump automatically starts, if you want to stop the
turbo-pump from outside, you have to connect the START/STOP (+) signal to the
+24 Vdc pin and the START/STOP (-) signal to the GROUND pin (this is the default
configuration of the cover connector.
ADAPTIVE SCROLL DRIVING DISABLE: Input signal to disable Adaptive Scroll
Driving function. With the supplied mating connector the Adaptive Scroll Driving
Disable (+) input is connected to the +24Vdc pin and the Adaptive Scroll Driving
Disable (-) input is connected to GROUND pin; in this condition the Adaptive Scroll
Driving function is disabled.
SOFT START: this input is used to provide a "soft start" to the pump; in this
condition the ramp-up time could be up to 20 min.
SPEED SETTING: PWM input signal to set the pump speed. The PWM signal
characteristics must be the following:
frequency: 100 Hz +/-20 %
amplitude: 24 V max
duty cycle range: from 25 % to 75 %
corresponding to a pump speed from 1100Hz to 1167Hz (see the
following diagram).
