the frequency reference value is saved even when powering down the inverter.
Refer to Figure 4.4.21. for an example.

03-0X =12: Main/ Alternative Run Switch Function
When function terminals conduct, run command source is set in alternative run command (00-03). When
functional terminal is set to 27 (Local/ Remote control selection), it will be precedential to main/alternative run
switch.
03-0X =13: Main/ Alternative Frequency Switch Function
When function terminals conduct, frequency command source is set in alternative frequency command
(00-06). When functional terminal is set to 27 (Local/ Remote control selection), it will be precedential to
main/alternative frequency switch. When PID function is active(10-03=XXX1B),this function is invalid and
main frequency is switched to PID function. When PID function is invalid, Main/ Alternative frequency switch
function is valid then.
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 – 8). 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
