System configuration and wiring
1. Core component configuration
Power supply circuit: MCCB (molded case circuit breaker) → noise filter → electromagnetic contactor → amplifier
Signal circuit: host controller → amplifier CN1 (I/O) → motor CN2 (encoder)
Peripheral accessories: Regenerative resistor (when regenerative energy is insufficient), DC reactor (to suppress harmonics), surge absorber
2. Key wiring requirements
Main circuit: The U/V/W phase line of the motor corresponds to the amplifier output terminal, and the FG terminal must be grounded (grounding resistance ≤ 100 Ω)
Encoder: Shielded twisted pair cable, maximum distance of 50m, single ended grounding of shielding layer
Control circuit: Shielded twisted pair cables are used for I/O signals, with a distance of ≥ 30cm from the main circuit to avoid interference
