19.2 b (Basic) Parameter Details
Run Command Source Selection
0000: Keypad
0001: External terminal control
0002: Communication control
1.) b000 = 0000: The inverter is controlled by the keypad.
2.) b000 = 0001: The inverter is controlled by the external terminals. The Stop key will function as an emergency stop
function. (Refer to parameter A010 description).
Note: For the safety of personnel and equipment, when b000 = 0001, please refer to parameter group A013, A014,
A019 and A018 for a detailed description.
3.) b000 = 0002: The inverter is RS485 communication controlled.
Operation modes for external
terminals
0000: Forward/stop - reverse/stop
0001: Run/stop - forward/reverse
0002: 3-wire control mode - run/stop
1.) When operation command b000 = 0001 (external terminal), b001 is valid.
2.) When operation command b000 = 0001 (external terminal), the stop button is available for emergency stop.
(Refer to A010 for detailed description).
3.) When both forward and reverse commands are ON, this will result in a stopped mode.

Fig. 19.1
Notes: 1 - In 3 wire control mode, terminal S1, S2 and S3 are not controlled by A050, A051 and A052.
2 - When b002 = 0001 reverse is prohibited. (See b002)
