Parameter Groups
‑188‑
17: Frequency upper limit reached
The terminal outputs an active signal when the running frequency reaches the
frequency upper limit (F0‑12).
18: Frequency lower limit reached (no output at stop)
If F8‑14 (running mode when frequency reference lower than lower limit) is set to
1 (stop), the terminal outputs an inactive signal no matter whether the running
frequency reaches the frequency lower limit.
When F8‑14 is set to 0 (run at the lower limit frequency) or 2 (run at zero speed)
and the running frequency reaches the lower limit, the terminal outputs an active
signal.
19: Undervoltage state
The terminal outputs an active signal when undervoltage occurs on the AC drive.
20: Communication setting
Whether the terminal is active or inactive is determined by communication
address 0x2001.
21: Reserved
22: Reserved
23: Zero‑speed running 2 (at stop)
When the output frequency is 0 during AC drive running, an active signal is output.
When the AC drive stops, the active signal is retained.
24: Accumulative power‑on time reached
The terminal outputs an active signal when the accumulative power‑on time of
the AC drive (F7‑13) exceeds the value of F8‑16 (Accumulative power‑on time
threshold).
25: Frequency‑level detection FDT2 output
When the running frequency is higher than the detected value, the DO outputs an
active signal. When the running frequency is lower than the result of the detected
value minus the frequency detection hysteresis value (F8‑28 x F8‑29), the active
signal is canceled.
26: Frequency 1 reached
When the running frequency of the AC drive is within the detection range of F8‑30
(Frequency detection value 1), the DO outputs an active signal.
Frequency detection range: F8‑30 ‑ F8‑31 x F0‑10 (Maximum frequency) to F8‑30 +
F8‑31 x F0‑10
27: Frequency 2 reached
When the running frequency of the AC drive is within the detection range of F8‑32
(Frequency detection value 2), the DO outputs an active signal.
Frequency detection range: F8‑32 ‑ F8‑33 x F0‑10 (Maximum frequency) to F8‑32 +
F8‑33 x F0‑10
28: Current 1 reached
When the output current of the AC drive is within the detection range of F8‑38
(Detection level of current 1), the DO outputs an active signal.
