English-2 PowerFlex 400 Adjustable Frequency AC Drive Quick Start
• Mount the drive upright on a flat, vertical and level surface.
• Protect the cooling fan by avoiding dust or metallic particles.
• Do not expose to a corrosive atmosphere.
• Protect from moisture and direct sunlight.
Maximum Surrounding Air Temperature
ATTENTION: An incorrectly applied or installed drive can result in
component damage or a reduction in product life. Wiring or application
errors, such as, undersizing the motor, incorrect or inadequate AC
supply, or excessive ambient temperatures may result in malfunction of
the system.
ATTENTION: The bus regulator function is extremely useful for
preventing nuisance overvoltage faults resulting from aggressive
decelerations, overhauling loads, and eccentric loads. However, it can
also cause either of the following two conditions to occur.
1. Fast positive changes in input voltage or imbalanced input voltages
can cause uncommanded positive speed changes;
2. Actual deceleration times can be longer than commanded
deceleration times
However, a “Stall Fault” is generated if the drive remains in this state
for 1 minute. If this condition is unacceptable, the bus regulator must be
disabled (see parameter A187).
