Wobbulation operation mode starts.
Xi=48 Not used
Xi=49 Program operation reset
When program operation (PLC) is active, if the input signal of this terminal is on,
and then program operation time is cleared, and program operation starts from
Section 1.
Xi=50 Alternate motor switching
During running, if input signal of the terminal is on, the inverter regulates the
output according to the parameters of Motor 2.
Xi=51 External fault input
During running, after the terminal receives external device fault signal, inverter
stops and enters fault status. The default is NO input of external fault, and it can
be set as NC input by FE-01(Terminal positive/negative logic).

EM303A provides 3 programmable output terminals including 2 multi-function output
terminals and 1 relay output terminal. There are 0
～32 program codes, user can define
output variables of terminals.
Two multi-function output terminals are in OC output mode. Output common port is
connected to COM. When selected program code is enabled, the electronic switch is
ON, and when it is disabled, the electronic switch is OFF. OC can be powered either
internally or externally, as shown in Figure 7-8(a) and 7-8(b) respectively. If it is
externally powered, the voltage range is required to be within 8~24V.
