Input signals circuit
Input signals of the driver are C-MOS inputs.
The signal state represents "ON: 0 to 0.5 V (L level)"
and "OFF: 4 to 5 V (H level)."

Changing the logic level setting of input signals
The logic level setting for input terminals DIN0 to DIN5 can be changed using the
MEXE02
.
Refer to the USER MANUAL for details.

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.

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 the USER MANUAL 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.
•
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.
