A-2 Supplemental Drive Information
Environment
(continued)
Atmosphere: Important: Drive must not be installed in an area
where the ambient atmosphere contains volatile or
corrosive gas, vapors or dust. If the drive is not going
to be installed for a period of time, it must be stored in
an area where it will not be exposed to a corrosive
atmosphere.
Relative Humidity: 5 to 95% non-condensing
Shock: 15G peak for 11ms duration (± 1.0 ms)
Vibration: 0.152 mm (0.006 in.) displacement, 1G peak
Electrical Voltage Tolerance: See page D-14
for full power and operating range.
Frequency Tolerance: 47-63 Hz.
Input Phases: Three-phase input provides full rating for all drives.
Single-phase operation provides 50% of rated current.
Displacement Power Factor: 0.98 across entire speed range
Efficiency: 97.5% at rated amps, nominal line volts
Maximum Short Circuit Rating: 85,000 Amps symmetrical
Actual Short Circuit Rating: Determined by AIC rating of installed fuse/circuit
breaker.
Control Method: Sine coded PWM with programmable carrier
frequency. Ratings apply to all drives (refer to the
Derating Guidelines in the PowerFlex Reference
Manual). The drive can be supplied as 6 pulse or 12
pulse in a configured package.
Carrier Frequency: 2, 3 or 4 kHz. Drive rating based on 2 kHz.
Output Voltage Range: 0 to rated motor voltage
Output Frequency Range: Standard Control – 0 to 400 Hz.
Frequency Accuracy
Digital Input:
Analog Input:
Within ± 0.01% of set output frequency.
Within ± 0.4% of maximum output frequency.
Frequency Control: Speed Regulation - w/Slip Compensation
(Volts per Hertz Mode)
0.5% of base speed across 40:1 speed range
40:1 operating range
10 rad/sec bandwidth
Speed Regulation - w/Slip Compensation
(Sensorless Vector Mode)
0.5% of base speed across 80:1 speed range
80:1 operating range
20 rad/sec bandwidth
Selectable Motor Control: Sensorless Vector with full tuning. Standard V/Hz with
full custom capability.
Stop Modes: Multiple programmable stop modes including Ramp,
Coast, DC-Brake, Ramp-to-Hold, and S-curve.
Accel/Decel: Two independently programmable accel and decel
times. Each time may be programmed from 0 - 3600
seconds in 0.1 second increments.
Intermittent Overload: 110% Overload capability for up to 1 minute.
150% Overload capability for up to 3 seconds.
Current Limit Capability: Proactive Current Limit programmable from 20 to
160% of rated output current. Independently
programmable proportional and integral gain.
Electronic Motor Overload Protection: Class 10 protection with speed sensitive response.
