SV-DA200 series AC servo drives Control mode applications

in the figure. They can be used to drive the relay coil or optical coupled load. The loading capacity is
shown in the figure.
When inductive loads such as relay coil are connected, a free wheel diode must be fitted as shown
in the figure; when optical coupler is connected, current limit resistor must be connected, otherwise
the drive will be damaged.
The local 24V power supply only can provide 100mA current. If the actual load current is larger
than 100mA, the user should provide the power supply by themselves. The recommended capacity is
greater than 500mA.
4.5.5 Wiring of frequency division output circuit of encoder feedback signal
Differential mode:
Open-collector mode:
Phase A, B and Z all provide differential output and open-collector output signals.
For differential output signal, it is recommended to use AM26C32 or equivalent differential
receiving chip and be sure to fit a terminal matching resistor of about 220Ω.
For the phase A, B, Z signal of open-collector output, as the signal pulse width is very narrow, the
user shall use high speed optical coupler to receive this signal.
Both output circuits have no isolation.
