• Axis 3: 2 • Axis 7: 6
• Axis 4: 3 • Axis 8: 7
(4) 4: Refer to the servo amplifier instruction manual for selection of the circuit breaker and electromagnetic contactor.
(5) 5: The status of forced stop input signal can be confirmed with "[Md.50] Forced stop input". Be sure that the forced stop 24 V DC
power supply is not used with the electromagnetic brake of the motor or the electromagnetic valve power supply.
