There are numerous operation mode of this servo drive (please refer to Chapter 6.1). Each
operation mode needs different I/O signal. In order to use the terminal in a more efficient way, the
selection of I/O signal has to be programmable. That is to say, users can choose the desired
DI/DO signal to meet the demand. Basically, the default setting of DI/DO signal has already have
the appropriate function which can satisfy the demand of normal application.
Users have to select the operation mode based on the needs first (please refer to Chapter 6.1 for
the introduction of each mode) and refer to the following DI/DO table to know the corresponding
default setting of DI/DO signal and Pin No of the selected mode in order to conduct the wiring.
The table below lists the default setting of DI/DO signal function and pin No:
The explanation of DO signal default setting is as the followings.

VDD is the +24 V power provided by the drive
17 and is for Digital Input (DI) and Digital Output
(DO) signal. The maximum current is 500 mA.
COM+ is the common input of Digital Input (DI)
and Digital Output (DO) voltage. When using
11
VDD, VDD should be connected to COM+. If not
45
using, it needs to apply the external power (+12
47
V ~ + 24 V). Its positive end should connect to
49
COM+ and the negative end should connect to
COM-.
VCC is the +12V power provided by the drive. It
is used

When the servo drive applies to the power and no
7 6 alarm (ALRM) occurs in control circuit and motor
power circuit, this DO is ON.
When the DI.SON is ON and the motor servo circuit

can operate smoothly, this DO is ON.
When the motor speed is slower than the setting

value of parameter P1-38, this DO is ON.
When the motor actual speed (r/min) is faster than
