XMV660 SERIES MV VSD

Maximum Motor Care

• Multi-step quasi-sinusoidal output voltage produced by the cascaded H-bridge power modules results in sinusoidal motor current and is low in dV/dt.
• Negligible THDi in motor current
• Suitable for retrofitting to existing motors
• No motor de-rating or cable length restrictions
• Multi-step technology offers low common mode voltage (CMV) thus eliminating voltage peaks at the motor terminals. Eliminating common mode currents means standard bearings can be used – no EDM.

Accurate, Flexible and Powerful Motor Control

• Solid motor control consisting of Power Electronics proven V/F, Power Motor Control (PMC) and Advanced Vector Control (AVC).
• PMC factory settings and motor parameters ensures perfect performance without the need to auto tune the motor.
• Should a power module fail the XMV660 will automatically bypass this cell and keep running at reduced power output.
• The on-board UPS gives control ride through during supply under voltage conditions permitting the drive to restart the motor once the supply voltage returns to normal.

Network Friendly and Very Efficient

• The multi-pulse phase shift transformer of 18 to 54 pulse minimises the THDi level ensuring the XMV660 won’t mess with your supply. Guaranteed conformance to IEEE519.
• Outstanding power factor of <0.95 above 20% load. Eliminates the need for separate PFC.
• Overall efficiency of >96% when operating above 40% load.

A MV Drive Needs Great Safety and Protective Features

The XMV660 integrates built-in hardware and software protections that reduce the risks associated with medium voltage installations.

An Input phase-shift transformer offers a wide variety of benefits to your installation

• Reduces short circuit current in an unlikely case of internal insulation breakdown.
• Protects input power stage from mains fluctuations and transients.
• Boosts output voltage by compensating for supply and motor voltage drops by using on site tap adjustments.
• The transformer voltage can be customised to suit different supply and motor voltages, thus eliminating the need for further transformers or switchgear.
•  The XMV660 monitors each individual power module offering multiple hardware and software protections.
• The XMV660 can be ordered with input protection modules, thus eliminating external protection switchgear.
• Safety system, mechanical interlocks, password protection and a warning buzzer will warn you of undesirable settings.
