Output signals circuit
Output signals of the driver are transistor open-collector outputs. The signal state represents a state of "ON: Carrying
current" or "OFF: Not carrying current" for the internal photocoupler rather than the voltage level of the signal.
ON voltage: 0.5 VDC maximum
External power supply: 4.5 to 26.4 VDC, 10 mA or less

Changing the logic level setting of output signals
The logic level setting for output terminals DOUT0 to DOUT3 can be changed using the
MEXE02
.
However, if the SPEED-OUT output is assigned, it cannot be changed.
Refer to p.55 for details.
Note
•
Be sure to suppress a current owing to the output circuit at 10 mA or less.
Connect a current limiting resistor R externally if the current exceeds this specied value.
If the driver is used without connecting a current-limiting resistor, it will be damaged.
•
When a relay (inductive load) is connected, provide a control measure for
the y-back voltage against the relay by connecting a diode. Or use a relay
with built-in ywheel diode.
