Reference input during b.b (d15, d16):
Description of action: When switch of this terminal acts, output of AC motor drive shall stop
immediately and motor run freely. After switch reset, AC motor drive 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.7
Up/down 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 AC motor drive 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 Program auto- operation reference starting (d19): cooperate with parameters of 5
th
group.
Input of Auto-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
AC motor drive 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
circuiting opened.
Counting reset (d22):
Description of action: Current counting display shall be reset by action of this terminal, and “C0”
shall be restored. Counting upwards of the AC motor drive from triggering signal shall not be
available until this signal disappears.
Function d23 is reserved.
JOG FWD (d24): Jog forward run. For relative application, see description of Parameter (1-13, 1-14
and1-15)
JOG REV (d25): Jog reverse run. For relative application, see description of Parameter (1-13, 1-14
and1-15)
Description of action: When external terminal contactor is OFF, motor shall coast to a stop in
accordance with Jog run deceleration time. For relative application, see description of Parameter
(1-13, 1-14). Jog run reference shall only be used when the AC motor drive in stop and [STOP] key
from the digital operator shall be available
d26 is reserved.
Wobble frequency function input (d27):
Description of action: If wobble frequency starting is manual, wobble frequency status shall be
available when terminals are closed; when terminals open, wobble frequency function shall be
cancelled and the operation frequency keeps at wobble frequency preset frequency A-02.
