2.
Digital output interfaces (C2)
The digital outputs use Darlington photo-coupler. It can be connected with relay,
photo-coupler. Please notic the following
:

Inverting the polarity of DC power source, which is provided by the user, can cause the servo
driver damage.

The maximum voltage of external DC power supply is 25V, the maximum output current is
50mA, and the total current for three channels is not in excess of 100mA.

When using relay like inductive loads, a free-wheel diode must be connected with the
inductive load in parallel. If the diode connects in wrong direction can cause damage to the
output circuit.

Owing to the low level of output is approximately 1V and cannot satisfy the TTL low-level
request, therefore cannot directly connect with the TTL circuit.
