After this terminal becomes ON, the inverter directly switches
over to the DC braking state.
After this terminal becomes ON, the inverter reports Err15 and
stops.
After this terminal becomes ON, the inverter does not respond
to any frequency modification.
After this terminal becomes ON, the PID action direction is
reversed to the direction set in FA.03.
In operation panel mode, this terminal can be used to stop the
inverter, equivalent to the function of the STOP key on the
operation panel.
It is used to perform switchover between terminal control and
communication control. If the command source is terminal
control, the system will switch over to communication control
after this terminal becomes ON.
After this terminal becomes ON, the integral adjustment
function pauses. However, the proportional and differentiation
adjustment functions are still valid.
After this terminal becomes ON, the frequency source X is
replaced by the preset frequency set in F0.08.
After this terminal is enabled, the frequency source Y is
replaced by the preset frequency set in F0.08
If the PID parameters switchover performed by means of DI
terminal (FA.18 = 1), the PID parameters are FA.05 to FA.07
when the terminal becomes OFF; the PID parameters are FA.15
to FA.17 when this terminal becomes ON.
If these two terminals become ON, the inverter reports Err27
and Err28 respectively, and performs fault protection actions
based on the setting in F9.49.
This terminal enables the inverter to switch over between speed
control and torque control. When this terminal becomes OFF,
the inverter runs in the mode set in Fb.10. When this terminal
becomes ON, the inverter switches over to the other control
mode.
When this terminal becomes ON, the inverter stops within the
shortest time. During the stop process, the current remains at
the set current upper limit. This function is used to satisfy the
requirement of stopping the inverter in emergency state.
In any control mode , it can be used to make the inverter
decelerate to stop. In this case, the deceleration time is
deceleration time 4.
When this terminal becomes ON, the inverter decelerates to the
initial frequency of stop DC braking and then switches over to
DC braking state.
When this terminal becomes ON, the inverter's current running
time is cleared. This function must be supported by F4.42 and
F4.53
