The terminal is used for fault reset function, the same as the
function of RESET key on the operation panel.
The inverter decelerates to stop, but the running parameters are
all memorized, such as PLC, swing frequency and PID
parameters. After this function is disabled, the inverter resumes
its status before stop.
If this terminal becomes ON, the inverter reports Err15and
performs the fault protection action. For more details, see the
description of F9.47.
The setting of 16 speeds or 16 other references can be
implemented through combinations of 16 states of these four
terminals.
Totally four groups of acceleration/deceleration time can be
selected through combinations of two states of these two
terminals.
The terminal is used to perform switchover between two
frequency sources according to the setting in F0.07
If the frequency source is digital setting, the terminal is used to
clear the modification by using the UP/DOWN function or the
increment/decrement key on the operation panel, returning the
set frequency to the value of F0.08.
If the command source is set to terminal control (F0.02= 1),
this terminal is used to perform switchover between terminal
control and operation panel control.
If the command source is set to communication control
(F0.02 = 2), this terminal is used to perform switchover
between communication control and operation panel control.
It enables the inverter to maintain the current frequency output
without being affected by external signals (except the STOP
command).
PID is invalid temporarily. The inverter maintains the current
frequency output without supporting PID adjustment of
frequency source.
The terminal is used to restore the original status of PLC
control for the inverter when PLC control is started again after
a pause
The inverter outputs the central frequency, and the swing
frequency function pauses
This terminal is used to count pulses
This terminal is used to clear the counter status.
This terminal is used to count the length
This terminal is used to clear the length
The inverter is prohibited from torque control and enters the
speed control mode.
X5 is used for pulse input.
