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).
INTERLOCK: input signal to control the pump ro-
tation. With the supplied cover connector the IN-
TERLOCK (+) signal is connected to the +24 Vdc
pin and the INTERLOCK (-) signal to the
GROUND pin; in this condition the pump is
stopped.
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%
64/74
