HOW TO USE COMMUNICATION CABLE
(cont.)
Information
■
Input circuit
•
It is a photocoupler input circuit.
•
The voltage must be 24 V
DC ± 10%.
•
It consumes a current of approximately 5 mA per input.
■
Output circuit
•
It is an open collector circuit.
•
The voltage must be 24 V DC ± 10%.
•
The peak output current is 20 mA per output.
■
Input/Output circuit
•
The absolute maximum ratings are 30 V for voltage and 20 mA for current.
The output signal wire must be connected only to a PLC (photocoupler input).
Do not directly connect a power supply to the signal output wire without using a
current-limiting resistor.
Doing so breaks the photocoupler.
Do not directly connect a relay, motor, lamp, or any other device to the signal
output wire to drive it.
Doing so may cause, for example, the surge voltage from the inductive load to
break the tool.
When applying a voltage to the signal output wire using an external power
supply, connect the positive side to the input/output wire and the negative side to
the COM.
When no communication cable is connected, the drive permission signal is
recognized as OFF.
Note that when the tool is turned on or off, a signal may be output.
