Example using G7TC-OC16.
Be sure to lock the connectors securely.
Note If a 24-VDC power supply is not provided, the Data Setting Console and exter-
nal cam output will not function.
In order to prevent malfunctions due to noise, conduct the following counter-
measures.
Use shielded wire for external cam output lines and resolver cable.
Be sure to wire power lines (e.g., AC power supply, electrical power lines) and
control lines (e.g., external cam output lines, resolver cables) in separate
ducts.
Be sure to mount a surge-absorbing diode or surge absorber to an inductive
load (such as a relay, solenoid, or electromagnetic valve). Use a surge-
absorbing diode with a voltage resistance of at least five times the circuit volt-
age.
