A–2 Specifications and Supplemental Information
Electrical
Input Data
Voltage Tolerance: –10% of minimum, +10% of maximum.
Frequency Tolerance: 48-62 Hz.
Input Phases: Three-phase input provides full rating for all drives.
Single-phase operation is possible for A & B Frame drives
at a derating of 50%.
Displacement Power Factor
A1-A3 Frame Drives: 0.80 standard, 0.95 with optional inductor.
A4 Frame & Up Drives: 0.95 standard.
Efficiency: 97.5% at rated amps, nominal line volts.
Max. Short Circuit Current Rating: 200,000A rms symmetrical, 600 volts (when used with AC
input line fuses specified in Chapter 2).
Control
Method: Sine coded PWM with programmable carrier frequency. Ratings
apply to all drives (refer to the Derating Guidelines on page A–3).
A Frame Drives 2-10 kHz. Drive rating based on 4 kHz (see pg. 1–1 for frame info).
B Frame Drives 2-8 kHz. Drive rating based on 4 kHz (see pg.1–1 for frame info).
Output Voltage Range: 0 to rated voltage.
Output Frequency Range: 0 to 400 Hz.
Frequency Accuracy
Digital Input: Within ±0.01% of set output frequency.
Analog Input: Within ±0.4% of maximum output frequency.
Volts per Hertz Ratio: Fully programmable.
DC Boost: No Boost, Auto Mode (8 settings w/programmable Run Boost re-
duction), Full Custom, Fan Mode (2), or
Fixed Mode (with independent Accel and Run Boosts).
Accel/Decel: Two independently programmable accel & decel times. Each time
may be programmed from 0 to 6000 seconds in 0.01 second incre-
ments.
Intermittent Overload: Constant Torque – 150% of rated output for 1 minute.
Current Limit Capability: Proactive Current Limit programmable from 20 to 160% of rated
output current. Independently programmable proportional and in-
tegral gain.
Inverse Time Overload Cap.Class 10 protection with speed sensitive response. Investigated by
U.L. to comply with N.E.C. Article 430. U.L. File E59272, volume 4/6.
