*2. When 11-58 = 0, and a run command is given and the acceleration / deceleration inhibit command is
active, the frequency reference and output frequency will remain at zero.
03-0X =12: Main/Alternative Run command Switching
Run command source is set by alternative run command (00-03) when function terminal is active. When
function terminal is set to 27 (Local/ Remote control selection), the priority will higher than the switch of
main/ alternative run command.
03-0X =13: Main/Alternative Frequency Command Switching
Frequency command source is set by alternative frequency command (00- 06) when function terminal is
active. When function terminal is set to 27 (Local/ Remote control selection), the priority will higher than the
switch of main/ alternative frequency command.
03-0X =14: Emergency stop (decelerate to zero and stop)
Refer to the "deceleration time of emergency stop" of parameter 00-26.
03-0X =15: External Baseblock Command (coast to stop)
Execute the base block command by the use of ON / OFF way of multi-function digital input terminal, and
prohibit the inverter output.
During run: When an external base block command is activated, the keypad displays "BBn BaseBlock
(Sn)", indicating the inverter output is turned off (n indicates the digital input number 1 – 6). Upon removing
the base block signal, the motor will run at the frequency reference. If speed seach from frequency
reference is active the inverter output frequency starts from the frequency reference and searches for the
coasting motor speed and continue to operate. If speed search is not active the output frequency starts at
0Hz.
During deceleration: When an external base block command is activated, the keypad displays "BBn
BaseBlock (Sn)", indicating the inverter output is turned off (n indicates the digital input number 1 – 6).
Upon removing the base block signal, the motor is stopped or will coast to a stop and the inverter will
remains in the stop condition.
During acceleration: When an external base block command is activated, the keypad displays "BBn
BaseBlock (Sn)", indicating the inverter output is turned off (n indicates the digital input number 1 – 6).
Upon removing the base block signal, the motor will run at the frequency reference. If speed seach from
frequency reference is active the inverter output frequency starts from the frequency reference and
searches for the coasting motor speed and continue to operate. If speed search is not active the output
frequency starts at 0Hz.
