6: Function as UP key for frequency adjustment
The terminal is used to increase the frequency when the frequency is set through the
terminal. Activating the terminal is equivalent to pressing and holding the increment
key. Deactivating the terminal is equivalent to releasing the increment key.
7: Function as DOWN key for frequency adjustment
The terminal is used to decrease the frequency when the frequency is set through the
terminal. Activating the terminal is equivalent to pressing and holding the decrement
key. Deactivating the terminal is equivalent to releasing the decrement key.
8: Coast to stop
Once the drive receives a stop command, it immediately stops output. The load then
coasts to stop based on the mechanical inertia. The AC drive stops output to shut
down. At this time, the power supply of the motor is cut off and the driving system is
in the free braking state. This is also known as inertia stop because the stop time is
determined by the inertia of the driving system.
9: Fault reset (RESET) The terminal is used to reset the AC drive upon faults. It is
equivalent to the STOP/RES key on the operating panel. This function allows you to
perform a reset upon the fault remotely.
10: Running pause
The drive decelerates to stop with all the operating parameters memorized (such as
PLC, wobble frequency, and PID parameters). When the terminal is inactive, the drive
resumes its status before decelerating to stop.
11: NO input of external fault
When an external signal is sent to the drive, the drive reports Err15.
12 to 15: Multi‑reference terminals 1 to 4
Multi‑reference is selected as the main frequency source. Sixteen speeds or sixteen
references can be set through combinations of sixteen states of these four terminals.
It is suitable for applications where the operating frequency of the drive does not
require continuous adjustment, and only several frequency values need to be used.
16 and 17: Acceleration/Deceleration selection terminals 1 and 2
Four groups of acceleration/deceleration time can be selected through combinations
of four states of these two terminals.
The acceleration time indicates the time required for the AC drive to accelerate from 0
to the acceleration/deceleration time base frequency (F0‑25). The deceleration time
indicates the time required for the AC drive to decelerate from the acceleration/
deceleration time base frequency (F0‑25) to 0.
18: Frequency source switchover
The terminal is used to select the frequency reference input modes. The frequency
reference is set through F0‑07 (Frequency reference superposition).
