iP5A
During unexpected power failure conditions, the iP5A can bring the load to a controlled stop, by utilizing the inertial
energy. This can prevent further process problems or accidents.
Safety Stop
This algorithm reduces deceleration time, thereby improving system efficiency.
Flux Braking Algorithm
Intelligent Control
By taking ambient temperature into account, the iP5A can automatically adjust the Carrier (Modulation) Frequency.
Automatic Carrier Frequency Change
The iP5A has optimized protective functions, such as safety stop and pre-excitation of the motor, amongst others.
Protection
Because of effectual functions and protection algorithms, the iP5A provides constant performance,
in spite of external power fluctuations.
During Power Dips or Momentary Power Outage, the drive output can be maintained by utilizing the residual mechanical
energy in the load as a regenerative source. The duration of the power-dip ride-through depends on the load
characteristics.
Improved System Management during Power Dips and Momentary Power Outages
In spite of external voltage fluctuations and lightning surges, the iP5A optimizes motor performance.
Constant and Stable Performance
Under damp conditions, leakage currents can occur when
using drives. These currents can cause a system failure.
The iP5A low-leakage PWM algorithm reduces these
leakage currents to ensure reliability of operation.
