There are numerous operation modes of this servo drive (please refer to section 6.1). Each
operation mode needs different I/O signals. 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 had
the appropriate function which can satisfy the demand of general applications.
Users have to select the operation mode based on the needs first (please refer to section 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.:

No.
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
47
(+12V ~ + 24V). 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 for providing the simple analog command
20
(speed or torque command). The maximum
current is 100 mA.

NO CONNECTION. This terminal is for internal
use only. Do not connect it, or it may damage the
