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.
