Mains connection Supply voltages for two ranges
– 3-phase 208 - 240V +10/-15%– 3-phase 380 - 480V +10/-15%
Supply frequency 48-63 Hz Displacement power factor 0.98 Disconnecting the internal RFI filter is required
when operating in floating, impedance grounded, or asymmetrically grounded networks
Low THD (total harmonic distortion) value thanks to patented swinging choke solution

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

Maintenance Assistant Control Panel’s Maintenance assistant
– Monitors cooling fan counter, consumed energy (MWh), running hours or the motor rotation
– 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
