Operation
7.1 Input Signal Pins
The input pin signed assignments are given in Table 7.1, and Figure 7.2.
The input signal pins function only when the input operation port is set to the parallel
port, expect pins for inputting the rotation INHIBIT signal and the rotation INHIBIT
enable signal.
Two abbreviations are used in Table 7.1:
COM: Common Pin IN: Input Pin

Pin Description
Pins for inputting the START signal.
The following two methods are available:
1) Short the circuits between (1)–(14). Then, short the
circuits between (2)–(14) for 0.3 seconds or more.
However, when inputting this START signal
simultaneously with switching "ON" the external power
supply, continue to short these pins for 10 seconds or
more.
2) Short the circuits between (1)–(2).
In this case, (14) is not used.
Pins for inputting the STOP signal.
1) When 1) above is used to start the STP pump, open the
circuits between (1)–(14) to stop the STP pump.
2) When 2) above is used to start the STP pump, open the
circuits between (1)–(2) to stop the STP pump.
Pins for inputting the RESET signal.
When a safety function operates, remove the cause of the
abnormality/error after confirming the STP pump has
stopped. When the cause of the abnormality/error is
removed, short the circuits between (1)–(15) for 0.3 seconds
or more to reset the failure signal (The "FAILURE" LED
extinguishes).
Pins for inputting the rotation INHIBIT signal.
The input pins are valid even when input operation port is
set to serial port.
When the pins (1)–(3) are opened, the STP pump does not
rotate despite the presence of a start signal. When these
pins are opened while the pump is operating, the pump
will stop (see Section 7.1.2).
When using this function, short the circuits between
(24)–(25) of the rotation INHIBIT enable signal.
