Altivar® 58 TRX AC Drives

Suggested Specifications

2.04 Application Data

a.The AC drive shall operate a [variable torque load, constant torque load, constant horsepower load, impact load].

b.The speed range shall be from a minimum speed of 0.1 Hz @ 100% breakaway torque to a maximum speed of 500 Hz. The speed range shall be selectable at 50 Hz, 60 Hz, 200 Hz, 500 Hz.

2.05 Environmental Ratings

a.The AC drive construction ½ HP to 5 HP 230 Vac and 1 HP to 7.5 HP 460 Vac shall be IP20/open according to Standard EN50178; models rated 7.5 HP to 10 HP 230 Vac and 10 HP to 20 HP 460 Vac shall be Type 1. Both are designed to operate as Pollution degree 2 conforming to

IEC 60664-1, EN50718, and NEMA ICS-1 Annex A. Drives above 20 HP 460 Vac and 15 HP 230 Vac shall meet Type 1 Pollution degree 3 according to IEC 60664-1, EN50718, and NEMA ICS-1 Annex A.

b.The AC drive will be designed to operate in an ambient temperature of 0 to 40 °C (32 to 104 °F).

c.The storage temperature range shall be –25 to +70 °C (–13 to 158 °F).

d.The maximum relative humidity shall be 95% at 40 °C (104 °F), non-condensing.

e.The AC drive will be rated to operate at altitudes less than or equal to 1000 m (3,300 feet). For altitudes above 1000 m, derate the AC drive by 1.2% for every 100 m (330 feet).

f.The AC drive will meet the IEC 68-2-6 vibration specification.

g.The AC drive shall be designed and constructed to be of touch-safe construction with the enclosure open to operator access according to IP20 standards.

2.06 Ratings

a.The AC drive shall be designed to operate from an input voltage of 208/230 ±15% Vac or 400/460 ±10% Vac.

b.The AC drive shall operate from an input voltage frequency range from 47.5 to 63 Hz.

c.The displacement power factor shall not be less than 0.95 lagging under any speed or load condition.

d.The efficiency of the AC drive at 100% speed and load shall not be less than 96%.

e.The constant torque overtorque capacity will be 150% for 1 minute [The variable torque overtorque capacity will be 110% for 1 minute].

f.The output switching frequency of the drive will be randomly modulated and selectable at 2 kHz, 4 kHz, 8 kHz, 12 kHz, or 16 kHz depending on drive rating for low noise operation.

g.The output frequency shall be from 0.1 to 500 Hz (selectable at 50 Hz, 60 Hz, 200 Hz, 500 Hz).

h.The AC drive will be able to provide rated motor torque at 0.5 Hz in a Sensorless Flux Vector mode using a standard motor and no tachometer feedback.

2.07 Protection

a.The AC drive design and all hardware options will meet IP20 standards and allow for touch-safe access with the front cover open for all AC drives.

b.Upon power-up the AC drive shall automatically test for valid operation of memory, option module, loss of analog reference input, loss of communication, [dynamic brake failure], DC to DC power supply, control power, and the pre-charge circuit.

c.The AC drive shall be protected against short circuits between output phases; between output phases and ground; on the control terminal outputs; and the internal supplies. The logic and analog outputs shall also be optically isolated.

d.The AC drive shall have a minimum of power loss ride-through of 200 ms. The AC Drive shall have the user-defined option of frequency fold-back to increase the duration of the power-loss ride- through.

e.The AC drive will have a selectable ride through function which will allow the logic to maintain control for a minimum of one second without faulting.
