Parameter Groups
‑330‑
12‑15: Multi‑reference terminals 1–4
The AC drive selects the multi‑reference as the main frequency. The settings of 16
speeds or 16 references can be implemented through combinations of 16 states of
these four terminals. It is suitable for applications where the running frequency of
the AC drive does not require continuous adjustment, and only several frequency
values need to be used.
16‑17: Terminal 1 to 2 for acceleration/deceleration selection
Four groups of acceleration and deceleration time can be switched through four
states of these two terminals. The acceleration time indicates the time required
by the AC drive to accelerate from 0 Hz to the acceleration/deceleration time base
frequency (F0‑25). The deceleration time indicates the time required by the AC
drive to decelerate from the acceleration/deceleration base frequency (F0‑25) to 0
Hz.
18: Frequency source switchover
Used to select the frequency reference input mode. The frequency reference is set
by F0‑07 (Final frequency reference setting selection).
19: UP and DOWN setting clear
When the main frequency is set through the operating panel and this terminal is
active, the frequency (set through the increment/decrement keys on the
operating panel) can be cleared, and the frequency will be reset to the value of
F0‑08.
20: Command source switchover terminal 1
When the running command is set through the terminal (F0‑02=1) and this
terminal is active, the control mode can be switched between the terminal and
the operating panel.
When the running command is set through communication (F0‑02=2) and this
terminal is active, the control mode can be switched between the communication
and the operating panel.
21: Acceleration/Deceleration inhibited
The terminal is used to maintain the current running frequency of the AC drive
regardless of changes of the external input frequency (unless a stop command is
received).
22: PID pause
PID is invalid temporarily. The AC drive maintains the current output frequency
without supporting PID adjustment of frequency source.
23: PLC state reset
The terminal is used to restore the AC drive to the initial state of the simple PLC.
24: Wobble pause
In the wobble process, when this terminal is active, the wobble function pauses
(the AC drive outputs at the center frequency).
25: Counter input
In the count process, when the terminal is active, a count pulse is input.
