Operation
7.1.1 Input Operation Port Setting
Set the input operation port to the parallel port when operating the STP pump via the
connector X2. The input operation port can be changed by "PORT SELECT IN" signal of
the connector X2 and "Remote Operation Mode" setting. When "PORT SELECT IN"
signal is closed, the input operation port will set to the parallel port automatically
regardless of the Remote Operation Mode setting. When the "PORT SELECT IN" signal
is opened, any input operation ports are selectable in the Remote Operation Mode (see
Table 7.2). The default setting of the Remote Operation Mode is "I/O Remote" (parallel
port). It can be set via serial communication, the STP-Link (optional accessory), or the
display unit iDT-001 (optional accessory).

7.1.2 Rotation INHIBIT Signal
When using rotation INHIBIT signal, short-circuit the "INHIBIT ENABLE IN" signal.
Relations between rotation INHIBIT signal input and pump operation state are shown
in Table 7.3.
Table 7.3 Rotation INHIBIT Signal Input
Signal input Pump operation
After short-circuit of rotation
INHIBIT input signal (A), the
START operation is performed (B).
INHIBIT IN
Close
Open
START operation
The pump accelerates when the START
operation is performed (B).
After the START operation (A), the
rotation INHIBIT input signal is
short-circuited (B).
INHIBIT IN
Close
Open
START operation
The pump does not accelerate when the
START operation is performed (A).
The pump accelerates when the rotation
INHIBIT signal is short-circuited (B).
The rotation INHIBIT input signal
is opened (A) during acceleration or
normal operation.
INHIBIT IN
Close
Open
START operation
The pump decelerates and stops when the
rotation INHIBIT input signal is opened
(A).
After the operation (A), the pump
continues deceleration and stops even by
short-circuiting the rotation INHIBIT
input signal (B). However, when the
START signal is input, the pump will
accelerate.
