When the drive stops in PLC mode and this
terminal function is enabled, the memorized PLC
operating information (operating stage, operating
time, operating frequency, etc.) will be cleared.
The driver will restart if the terminal function is
disabled. See F9.
41: clear the counter to zero
Short-circuit the terminal with COM, this function
is to clear to zero and is used in conjunction with
function NO.42.
42: input signal to trigger the counter
This terminal is used to input counting pulse signal
to the internal counter of the driver. The counting
value increase by 1 each time receiving one
impulse (decrease by 1 for down-counting). The
max. pulse frequency is 200Hz. See F7.31~F7.33.
43: timing trigger input
Trigger port of internal timer. See F7.35~F7.36.
44: timing zero clearing
Short-circuit the terminal with COM, this terminal
is to clear the internal timer to zero and is used in
conjunction with function NO.43.
45: external impulse frequency input(only effective to
X6)
This function terminal is pulse input port of
principle frequency channel A, and is only effective
to X6, and is used in conjunction with F0.07.
46: clear the length information
When this function terminal is effective, the
information of F9.69 (actual length) will be cleared
to get prepared for recounting. See F9.67~F9.73.
47: Input the signal of length(only effective to X6)
This function is effective only to multi-function
input terminal X6, and the impulse signal received
by this function terminal works as length setting.
The number of received impulse has a connection
with the length, which is introduced in
F9.67~F9.73.
48: switch speed and torque control
When selection condition (terminal switch) of
speed and torque control is valid, this terminal is
effective and torque control is on; if this terminal
is ineffective, the speed control is on. See
F4.10~F4.11 for relevant parameter setting (F4.11
is the delay time of speed and torque switch).
49: prohibit torque control
Torque control is prohibited.
50~55: reserved
56~57: reserved
58: start/stop (manual)
When this terminal is valid, frequency is given by
AI1, PID control is not conducted, and controlled
by interlock signal. The earlier input interlock
signal will start first. If input together, start the one
corresponding smaller number.
59: running allowed (X2)
This terminal is used to control start/stop of VFD,
normally connecting signal of external water
