Hardware Overcurrent Trip:

200% of drive rated

100% of 3 sec. rating (158…210%)

143% of 3 sec. rating (215…287%)

Line transients: up to 6000 volts peak per IEEE C62.41-1991

Control Logic Noise Immunity: Showering arc transients up to 1500V peak

Power Ride-Thru: 15 milliseconds at full load

Logic Control Ride-Thru: 0.5 seconds minimum, 2 seconds typical

Ground Fault Trip: Phase-to-ground on drive output

Short Circuit Trip: Phase-to-phase on drive output

Electrical AC Input Voltage Tolerance: See page 11

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 on Frames 1…7 provides up to

50% of rated current at 25 °C (77 °F) surrounding temperature. Single-phase operation is not recommended

for Frames 8 and larger.

DC Input Voltage Tolerance: ±10% of Nominal Bus Voltage (above)

Displacement Power Factor: 0.98 across entire speed range

DC Link Impedance: ≥ 5%

Efficiency: 97.5% at rated amps, nominal line volts

Maximum Short Circuit Rating: 200,000 Amps RMS symmetrical (20F & 20G drives only)

Actual Short Circuit Rating: Determined by AIC rating of installed fuse/circuit breaker. See page 53

for 21G drives

Drive to Motor Power Ratio

Battery: User installed CR1220 lithium coin cell battery provides power to the real time clock (optional, not supplied).

Preserves the clock setting in the event power to the drive is lost or cycled. Approximate life is 4.5 years with

dive unpowered, or lifetime if drive is powered.
