3.3 Supplying Power for Internal Circuit Drive
Always make sure an external +24V DC power supply is connected to the pins for external input power
supply (pin No. A20 and B20).
The applied 24V DC passes through an internal DC/DC converter and is converted to 5 V DC voltage. It
is then supplied to the various internal circuits as a power supply for internal circuit drive of the pulse
command output pin.
3.3.1 Line Driver Output Type
3.3.2 Transistor Output Type
The power supply for the pulser command output circuit can be taken from the 5V DC out put pins (pin
No. A1, A2, A10 and A11)
Note:
When open collector pulse output (Transistor output) is used, the value of 15 mA per signal should be
used as a guide. If exceeds the 15 mA, the appropriate resistance should be added.
