 Note:
In terminal control mode, for 2-wire operating mode 1 and
2, although the terminal is enabled, the drive will not run
forward or reverse when the drive stops due to the STOP
command from terminal function 11 or 35 (see
F7.00~F7.07), PLC stop after single cycle, stop due to the
arrival of fixed length, pressing STOP key. If you need to
start the drive again, enable FWD/REV again. However,
when the drive stops due to a fault, it will start immediately
if the terminal FWD/REV is enabled and the fault is
cleared.
F7.09 UP/DN rate
Range:0.01~99.99Hz/s【1.00Hz/s】
F7.09 is used to define the change rate of reference
frequency that is changed by terminal UP/DN.
F7.10 Bi-direction open-collector
output terminal Y1
Range:0~19【0】
F7.11 Bi-direction open-collector
output terminal Y2
Range:0~19【1】
F7.12 Output functions of relay
Range:0~19【16】
Refer to section 3.3.2 for the output characteristics of Y1
and Y2 that are bi-direction open-collector output
terminal and the relay’s output terminal. Table 5-11
shows the functions of the above 3 terminals. One
function can be selected repeatedly.

In Table 5-11:
0: Drive running signal (RUN)
When the drive is in operating status, there will be
running indication signal output by this terminal.
1: Frequency arriving signal (FAR)
See F7.13.
2: Frequency detection threshold (FDT1)
See F7.14~F7.15.
3: Frequency detection threshold (FDT2)
See F7.16~F7.17.
4: Overload signal (OL)
The terminal outputs the indicating signal if the drive’s
output current is higher than the value defined by FL.05
and the overload time is longer than the time defined by
