Motor connection ACS550 motor connection range and motor

nominal values:– 208 to 240 V input (3~): Motors 115 to 345 V (3~) and 0.75

- 75 kW (0.8 - 100 hp)– 380 to 480 V input (3~): Motors 200 to 600 V (-01 types,

3~) / 230 to 690 V (-U1 types, 3~) and 0.75 - 355 kW (1 - 500 hp)

Frequency 0 to 500 Hz Switching frequency

– 0.75 to 110 kW: 1 / 4 / 8 / 12 kHz– Up to 355 kW: 1 / 4 kHz– With 8 and 12 kHz

Set parameter 2607 SW FREQ CTRL = 1 (ON) which allows the drive to reduce the switching frequency if/when the drive’s internal temperature exceeds 90°C (8kHz) or 80°C (12kHz)

OR Derate with 8kHz PN/Phd and I2N/I2hd to 80% (8 kHz), with 12 kHz PN/Phd

and I2N/I2hd to 65% & ambient temperature maximum to 30°C

– Gives indication of need for preventive maintenance of the drive, the motor or run application

Maintenance intervals defined to– Heatsink temperature check and cleaning depends on the dustiness

of the environment typically every 6-12 months– Main cooling fan replacement every six years – Internal enclosure cooling fan replacement (IP 54/UL Type 12 units)

every three years– Capacitor change (frame sizes R5 and R6) every ten years– Battery replacement in the Assistant Control Panel every ten years
