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/alterna-
tive 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 pro-
hibit 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 Base-
Block (Sn)”, indicating the inverter output is turned off (n indicates the digital input number 1 – 8). Upon remov-
ing 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 Base-
Block (Sn)”, indicating the inverter output is turned off (n indicates the digital input number 1 – 8). Upon remov-
ing the base block signal, the motor will run at the frequency reference. If speed seach from frequency refer-
ence 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.
