SSI700 User Manual Operation, Display and Application Example

Figure 4-6 Setting of using the DIP switch for start/stop
In the preceding figure, when SW1 is ON, the AC drive instructs forward rotation; when
SW1 is OFF, the AC drive stops. When SW2 is ON, the AC drive instructs reverse
running; when SW2 is OFF, the AC drive stops. If SW1 and SW2 are ON or OFF
simultaneously, the AC drive stops.
Example 2:
To use the electromagnetic button as the start/stop source, and allocate the startup signal
to DI2, stop signal to DI3 and reverse rotation signal to DI4, perform the setting as shown
in the following figure.
Figure 4-7 Setting of using the electromagnetic button for start/stop
In the preceding figure, SB1 must stay ON during normal start and running. The AC drive
stops immediately after SB1 becomes OFF. The signals from SB2 and SB3 become valid
once they become ON. The running state of the AC drive is determined by the final
actions on the three buttons.
2: Communication control
The most common configuration is when the host computer is used to control running of
the AC drive by means of communication, such as the RS485. The SSI700 interacts with
the user programmable also by means of communication.
Figure 4-8 Setting for start/stop using the communication control mode
When 13-04 is set to a non-zero number, the function of automatic AC drive stop upon
communication timeout is enabled. This prevents uncontrollable AC drive running due to
faults of the communication cable or the host computer.
