Frequency command2/1 switch (d12)
Description of action: when it is used to set the switching action of terminals. The frequency source of inverter will be
switched to 2-01 given (Frequency command 2) from 2-02 given (combination way of frequency sources) and return
to 2-02 given when the switch is turned off.
Accel/decel inhibition reference input (d13)
Description of action: In performing Accel/decel inhibition function, Accel/decel of inverter shall be stopped
immediately. When this function is cancelled, Accel/decel of AC motor drive shall be continued from inhibition place.
This reference shall only be available during acceleration or deceleration of the inverter.
Select 1
st
and 2
nd
accel/decel time (d14):
Description of action: Prior to closing of terminals switch, the accel/decel time of inverter shall be in accordance with
setting of Parameter 1-09 and 1-10. During switch closing, accel/decel time shall be in accordance with setting of
Parameter 1-11and 1-12. If inverter is in constant speed, changing of switches shall not influence output frequency,
which shall be effective when acceleration or deceleration of inverter is performing.
Reference input during external alarm (d15, d16):
Description of action: When switch of this terminal acts, output of inverter shall stop immediately and motor run freely.
After switch reset, inverter shall firstly track upwards from frequency before interruption to holding rotating speed,
and then accelerate to set frequency. Even if motor has stopped completely after b.b, speed tracking shall be
performed once switch reset
Up/down frequency reference input (d17, d18):
Description of action: This parameter has to match with 2-00 or 2-02 (when set as 6 or 7) to modify the given
frequency. When switch of this terminal in action, frequency of inverter shall happen the corresponding modification.
The increase and decrease rate of frequency is determined by acceleration and deceleration time. It is valid only in
operation state. The given frequency is cleared to 0 when stop.
Input of Pattern - operation command (d19):
Cooperate with parameters of 5
th
group.
Input of Pattern-program operation pause reference (d20):
Cooperate with parameters of 5
th
group.
Description of action: When switch for program auto operation is in operation, output frequency of inverter shall run in
accordance with setting of Parameter group 5-00 to 5-06. Pause terminal can interrupt running program during
running, and after reset, operation program shall be performed continuously. For detailed description for action, see
Parameter 5-15.
JOG frequency reference (d21):
Description of action: When external terminal is set with this function, JOG set frequency (1-15) shall be available by
short circuiting of this terminal; original frequency reference shall be reset after the circuit open.
Count reset (d22):
Description of action: Current counting display shall be reset by action of this terminal, and “C 0” shall be restored.
Counting upwards of the inverter from triggering signal shall not be available until this signal disappears.
Function d23 is reserved.
