Operation
7.2 Output Signal Pins
The output pin signed assignments are given in Table 7.4 and Figure 7.3.
The pins function when the input operation port is either in parallel port setting or
serial port setting.
Three abbreviations are used in Table 7.4:
N.O OUT : Normal Open Output Pin
N.C OUT : Normal Close Output Pin
COM : Common Pin
Table 7.4 X2 REMOTE Output Signal Pins
Pin Description
Pins for outputting the POWER ON state signal.
These pins are closed when magnetic bearing functions
and the rotor levitates.
This output is opened at a power failure.
Pins for outputting the ACCELERATION state signal.
These pins are closed when the STP pump is in
acceleration.
Pins for outputting the NORMAL OPERATION state
signal.
When the STP pump is in rated operation, the pins
between (18)–(6) are closed, and the pins between (19)–(6)
are opened.
Pins for outputting the BRAKE state signal.
These pins are closed when the STP pump is in brake.
Pins for outputting the FAILURE signal.
When an abnormality/error is detected, the pins between
(8)–(21) are closed, and the pins between (9)–(21) are
opened.
Pins for outputting the WARNING signal.
These pins are closed when the STP pump is WARNING
state. Refer to Section12, "WARNING Function" for the
warning.
Pins for outputting the parallel port select state signal.
When the input operation port is set to the parallel port
(I/O REMOTE), the pins between (11)–(23) are closed.
