One product, 5 control modes:
– IFD (Inverter Frequency Drive): vector modulation function for general-purpose applications (V/f pattern).
– VTC (Vector Torque Control): sensorless vector function for high-torque performance applications.
– FOC (Field Oriented Control): vector function with encoder for high torque accuracy and wide speed range.
– SYN (Synchronous): vector function for brushless PMSMs featuring high torque accuracy and high energy efficiency.
– RGN (Regenerative): regenerative sinusoidal AC/DC power supply unit, PF =1, for direct power supply of a series of drives.
Outstanding programming flexibility for each specific industrial application
– Smart Voltage Control now available: innovative algorithm hindering DC voltage increase with no need to apply external braking resistors.
– Open-loop speed accuracy: ±0.5% of max. speed. Closed-loop speed accuracy(with encoder): <0.01% of max. speed.
N.4 overload classes

The following configuration options may be integrated into the product:
– Breaking unit: configuration with braking unit integrated up to size S32 included. An external braking unit is available for sizes greater than S32.
– EMC Filter: Product version featuring integrated input filters in compliance with EN61800-3 2nd ed. In that case, the product ID is differentiated by suffix A1, A2, B. The integrated filters limit disturbance within the allowable ranges.
– Degree of protection IP54: Models with degree of protection IP54 available up to size S32 included (220kW).
– Operating devices: Set of operating devices on the front door, including a potentiometer, a mushroom-head push-button and a key-operated selector switch. Available for IP54 models only.
– Sinus Penta Parallel, configuration in parallel of 2 or 3 drives to control a single motor; available for size S41, S42, S51, S52. Benefits given by this solution: lower cost; improved stock management—the product may be modified for the connection in parallel by way of a special kit available on demand; easier repairings/replacement; space-saving.
– 12-pulse or 18-pulse power supply: from size S41 up, power supply may be 12-pulse/18-pulse to reduce the current harmonic contents in the power supply line.
– The PENTA MARINE drive in Regenerative configuration enables bidirectional interface with the mains, with power factor = 1 (true AFE application). Its true sine wave also enables dramatically reducing the THD below 5% and obtaining THDV = 0.
– Extensive range of external accessories: input and output filters, encoder, resolver, braking resistors, etc.
