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

Single phase 200V (SGDS): L1/L2 connected to single-phase power supply, B1/B2 connected to regenerative resistor, CN2 connected to encoder, CN1 connected to control signal

Three phase 200V (SGDH): L1/L2/L3 connected to three-phase power supply, 1/2 terminal connected to DC reactor, other interfaces consistent with single-phase
