Ten's digit: DI2 valid mode.0, 1 (same as DI1)
Hundred's digit: DI3 valid mode.0, 1 (same as DI1)
Thousand's digit: DI4 valid mode.0, 1 (same as DI1)
Ten thousand's digit: DI5 valid mode.0, 1 (same as DI1)
These parameters are used to set the valid mode of DI terminals.
0: Low level valid
The DI terminal is invalid when being connected with COM, and valid when being disconnected from COM.
1: High level valid
The DI terminal is valid when being connected with COM, and invalid when being disconnected from COM.
5.5 Group b4: Output Terminals
The EM15 provides an analog output (AO) terminal, two relay terminal and a FM terminal (used for high-speed pulse
output or open-collector output signal output) as standard. If these output terminals cannot satisfy requirements, use
an optional I/O extension card.

Pulse output
1
Open- collector output terminal
The FMP terminal is programmable multiplexing terminal. It can be used for high-speed pulse output (FMP), with
maximum frequency of 100.00 kHz. Refer to b6-00 for relevant functions of FMP. It can also be used as open
collector switch signal output (FMR).

These 3 parameters are used to select the functions of the digital output terminals.
The functions of the output terminals are described in the following table.
Value
Function
Description
0
No output
The terminal has no function.
1
Ready for RUN
If the frequency inverter main circuit and control circuit become stable, and
the frequency inverter detects no fault and is ready for RUN, the terminal
becomes ON.
2
Frequency inverter running
When the frequency inverter is running and has output frequency (can be
zero), the terminal becomes ON.
3
Fault output (free stop)
When the frequency inverter stops due to a fault, the terminal becomes ON.
4
Fault output(free stop fault,
no output at under-voltage)
When the frequency inverter stops due to a fault, the terminal becomes ON.
But there is no output when under voltage.
5
Swing frequency limited
If the set frequency exceeds the frequency upper limit or lower limit and the
output frequency of the frequency inverter reaches the upper limit or lower
limit, the terminal becomes ON.
6
Torque limited
In speed control mode, if the output torque reaches the torque limit, the
frequency inverter enters the stall protection state and meanwhile the
terminal becomes ON.
