Operation With External Signal; External Operation - Toshiba TOSVERT VF-AS1 Instruction Manual

7. Operation with external signal

7.1

External operation

The inverter can be freely controlled externally.
Parameters must be differently set depending on the operation method. Make sure of the operation method before
setting parameters, and set parameters properly to the operation mode according to the procedure mentioned below.
[Steps in setting parameters]
Operation signal:
operation panel
Speed command:
operation panel
Refer to Section 5.5
Example 1.
In case of control panel operation command input
 =  (Operation panel input
enabled)
In case of control panel operation command input
 =  (Operation panel input
enabled)
Check of external signal conditions
Operation signal: Operation signal:
terminal board operation panel
Speed command: Speed command:
operation panel terminal board
Refer to Section 5.5 Refer to Section 5.5
Example 2. Example 3.
In case of run/stop with external input
= (Terminal input enabled) *
*Sink logic and source logic (logic of input/output
terminal) are switchable to each other.
For details, refer to Section 2.3.2 .
In case of run/stop with external input
 =  (VI/II (voltage/current input))
