Application Precautions
• Do not touch the Module terminals while the power is ON.
Touching live terminals may cause electric shock.
• Construct an emergency stop circuit and an interlock circuit outside of the GL120
and GL130.
The absence of emergency stop and interlock circuits may result in machine
damage or accidents should the GL120 or GL130 fail.
Install an Emergency Stop Circuit Outside the GL120 and GL130.
An emergency stop circuit for the control system should not be constructed
using the ladder programming in the GL120 and GL130. Always construct the
emergency stop circuit externally using a relay circuit, as shown in the figure
below.
Use an N.C. contact (mechanical contact) in the emergency stop switch. The
main power supply to the servo must be cut off by pressing the switch.
Failure to provide an emergency stop circuit as described above, may result in
failure of the emergency stop when input circuits fail or cables break, and may
cause machine damage or injury.
