Grounding terminals
Mains power terminals (R/L1, S/L2, T/L3):
Connect these terminals (R/L1, S/L2, T/L3) via a non-fuse breaker or earth leakage
breaker to 3-phase AC power (some models to 1-phase AC power) for circuit
protection. It is unnecessary to consider phase-sequence.
The wire between the three-phase AC input power supply and the Main circuit
terminals (R/L1, S/L2, and T/L3) must be connected to a non-fused switch.
Please make sure to fasten the screw of the main circuit terminals to prevent sparks
which is made by the loose screws due to vibration.
Verify the voltage of power supply and the associated maximum available current.
Please refer to Chapter 1 Descriptions of Specifications.
If the Hybrid Servo Controller is equipped with a leakage circuit breaker for leakage
protection, please select the circuit breaker that has a sensing current above 200mA
and action time over 0.1 second to avoid malfunction.
Please use isolation wire or wire tube for power supply wiring and ground the
isolation layer or both ends of wire tube.
Output terminals for main circuit (U, V, W) :
The output side of Hybrid Servo Controller cannot be connected with advance phase
capacitor, surge absorber, advance phase capacitor, or L-C and R-C filters.
