EA180 Series Servo Drive Users Manual 3.8.3 Torque control mode Figure 3-26 Torque control mode standard wiring diagram 3.9 Notes for control circuit wiring The control circuit cable and the power cable must be separated at a minimum distance of 30cm. If the control circuit cable is short and needs to be extended, please ensure that the shield is reliably connected to ensure reliable shielding and grounding. The + 24V of servo drive is referenced by COM, and + 5V/+ 10V is referenced by GND. The load should not exceed the maximum allowable current, otherwise the drive will not work properly. Try to use the shortest command input and encoder cables.
Please use cables above 1.5 mm 2 for grounding. Single ground point is required. 41 Standard connection uses the internal +24V power supply by default +24V power supply COM+ S-ON DI1 Servo enabled ALM-RSTDI2 Alarm reset clear No positive drive P-OT DI3 No negative drive N-OT DI4 State input DI5 1.
