Danfoss Drives

Danfoss DrivesMV drive designed with you in mind Danfoss’ unsurpassed experience in advanced AC drive technologies makes the VACON® 1000 air-cooled MV drive the preferred choice for industrial medium-voltage general purpose applications, especially for variable torque loads such as pumps and fans in the low and mid-power range. The standalone version, available at 215 A and below, is one of the most compact and versatile multi-level MV drives in its class. Feature High reliability High MTBF Electronic bypass Power cell redundancy Low-voltage (LV) ride-through High temperature operation Harsh environment Redundant cooling fan UPS for control voltage (DC) Air filter clogging sensor Detailed fault monitoring External auxiliary power (LV) Safety Door interlock (IEC versions: electromagnetic, UL versions: mechanical) Residual voltage indicators PTC sensors for temperature monitoring MV drives standard compliance Fiber optic cables between MV and LV control parts Low ownership cost Less than 5% THDi Designed for 20 years of operation High total efficiency >96.5%, including transformer Only front access required for installation and maintenance No special requirements on motor insulation Up to 2000 m operation Process Performance Vector control U/f multipoint control Different autotuning modes Configurable overload Overvoltage prevention during deceleration Voltage boost Selectable for variable torque or constant torque rating Multi-motor applications System bypass (Manual, Auto, Synchronous) User-friendly Easy and simple selections Touch screen as standard Commissioning tool Event log Fieldbus communication Space saving High power density Standalone design ( ≤ 215 A, ≤ 6.9 kV) Simple cable installation Benefit Up to 200,000 hours of non-stop operation (depending on voltage class and current rating) IGBT based power cell bypass function enables fast (1 ms) reaction time (optional, +PPCB) Continued full power operation in case of fault in power cell (optional, +PPCR) Allows for continued operation during <100 ms grid voltage sag down to -30% of nominal input voltage Up to +50° C derated operation to avoid overheating IP31 as default, optional IP42, and chemical environment protection level IEC 660721: Class 3C2 Enables non-stop operation in case of a fan failure and extended overall lifetime (optional, +QDFR) Control stays on in case of supply interruptions Additional protection to prevent overheating Alarm and fault information for reduced downtime External source input for cooling fans (optional, +QDEX) Prevents opening of cabinet door unless mains power is off LEDs and HMI as well as visual DC-link voltage indicators on power cells provide complementary information for increased safety Transformer thermal protection Complies with international MV drive safety requirements according to applicable IEC and UL standards Galvanic isolation between LV controls and MV section Causes very low grid harmonics, minimal network disturbances, complies with IEEE-519 Long lifetime when the required operating conditions are met Short return on investment Easy service access, saves space in electric room (no back-access needed) Motor-friendly Install the drive in the optimal location, not necessarily next to motor Closed-loop and sensorless vector control for applications requiring more percise control Increases efficiency in pump and fan applications Motor autotuning with three (3) different modes for easier start-up (coupled, uncoupled or non-rotational motor) Up to 300% maximum torque limit (with base load derating) Automatic limit control during fast deceleration to avoid overvoltage tripping Booster function for high starting torque requirements Optimal drive selection according to application needs Drive can be configured for alternating change-over of up to 8 motors (VSD to DOL), optional bypass switchgear needed Preconfigured bypass configurations (to and from DOL) including make-before-brake switch over (optional, +PMBP Manual motor bypass, +PABP Automatic motor bypass, or +PSBP Synchronous transfer for 1 motor only) Wide variety of standard options supports flexible configuration HMI 7’’ screen as default, optional 10’’ screen (+MHMI), for local control and monitoring PC tool for parameter setting with embedded oscilloscope-like function Log up to 500 events with event description Most common communication protocols available for flexible system control (optional) Standalone version with smallest footprint in the market available at 215 A and below ( ≤ 6.9 kV) No on-site interconnection of separate sections needed Allows for top and bottom cabling for input and output power and control 2 Danfoss Drives · DKDD.PFP.909.A 2 .02Page 1Page 3
