NOTE:
1. Main-circuit terminals spec. is M3.
2. Main-circuit wiring is 600V 14AWG max.
3. Unscreened wiring between drive and motor
should not exceed 330 ft. (100m).
(1) 100 ft. (30m) below, the PWM carrier
frequency should be 15kHz below.
(2) 165 ft. (50m) below, the PWM carrier
frequency should be 10kHz below.
(3) 300 ft. (100m) below, the PWM carrier
frequency should be 5kHz below.
4. Voltage drop (V) = √ 3 • line resistance
(Ω.Km) • line lengfh (m) • Current (A) • 10
5. Screened wiring between drive and motor
should not exceed 50 ft. (15m).
Connection for optional brake resistor.
