40：Switchover between auxiliary frequency source Y and preset frequency
After this terminal is enabled, the frequency source Y is replaced by the preset frequency
set in P0.02.
43：PID parameter switchover
If the PID parameters switchover performed by means of DI terminal (P6.18 = 1), the PID
parameters are P6.05 to P6.07when the terminal becomes OFF; the PID parameters are
P6.15 to P6.17 when this terminal becomes ON.
44～45 ： User-defined fault 1,2
If these two terminals become ON, the AC drive reports E-32 and E-33 respectively, and
performs fault protection actions based on the setting in PA.46.
47：Emergency stop
When this terminal becomes ON, the AC drive 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 AC drive in emergency state.
48：External STOP terminal 2
In any control mode (operation panel, terminal or communication), it can be used to make
the AC drive decelerate to stop. In this case, the deceleration time is deceleration time 4.
49：Deceleration DC braking
When this terminal becomes ON, the AC drive decelerates to the initial frequency of stop
DC braking and then switches over to DC braking state.
50：Clear the current running time
