8 Remote Input/Output Signal Connector
The remote input/output signal connector (REMOTE CONNECTOR CON40) is
used to input and output remote signals.
This connector is of GP-IB type
*1
(24-pin, receptacle).
Four abbreviations are used in Tables 8.1 and 8.2:
N.O :Normal Open N.C :Normal Close
IN :Input Pin OUT :Output Pin
8.1 Remote Input Signals
Remote input signals function during REMOTE operation only.
Use input signals according to Table 8.1 and Figure 8.1.
Table 8.1 Remote Input Signals
Pin Description
POWER ON (13) (1)
DC24V IN
+ -
Pins for inputting the POWER ON signal.
Input 24 V DC between these pins for 0.3 seconds or
more, and the magnetic bearing functions and the rotor
levitates ((1): "+"; (13): "-").
POWER OFF
(
14
)
(2)
DC24V IN
+ -
Pins for inputting the POWER OFF signal.
The POWER OFF signal has priority over the POWER
ON signal.
Input 24 V DC between these pins for 0.3 seconds or
more, and the magnetic bearing stops and the rotor
lands ((2): "+"; (14): "-").
MOTOR START(15) (3
)
DC24V IN
+ -
Pins for inputting the START signal.
Input 24 V DC between these pins for 0.3 seconds or
more, and the STP pump starts to accelerate ((3): "+";
(15): "-").
MOTOR STOP (16) (4)
DC24V IN
+ -
Pins for inputting the STOP signal.
The STOP signal has priority over the START signal.
Input 24 V DC between these pins for 0.3 seconds or
more, and the STP pump stops ((4): "+"; (16): "-").
