380-480 V.....1.1 kW - 1000kW
525-600 V.....1.1 kW - 90 kW
525-690 V.....11 kW - 1,4 MW


Features and benefits



Enclosures
IP20/chassis, IP21/NEMA 1, IP55/NEMA 12 and IP66/NEMA 4X

Dedicated HVAC features Auto tuning of the PI controllers
With auto tuning of the PI controllers, the drive monitors how the system reacts on corrections made by the drive - and learns from it, so that precise and stable operation is achieved quickly. 

Automatic Energy Optimization
The standard feature AEO provides optimized motor magnetization at all speeds and loads. This increases energy efficiency by 5-15% for partial loads. 

Energy monitoring
The VLT® HVAC Drive provides a complete range of energy consumption information, which helps identify low-efficiency components in the HVAC system. 

PM motor support 
Support for any non salient permanent magnet motor up to 22 kW for better system efficiency. For more information, please see our brochure “EC+ is the smart trend in HVAC Drive Technology” above. 

Automated Resonance Monitoring
The drive can easily be set to avoid frequency bands at which connected fans create resonances in the ventilation system. This reduces installation time and system wear. 

Fan Belt Monitoring
From the relation between current and speed, the VLT® HVAC Drive is able to reliably recognize a broken belt. 

Fire Override Mode
In Fire Override Mode, the VLT® HVAC Drive will not react to control signals, warnings or alarms. It will continue reliable operation as long as possible and run until it is eventually destroyed itself to ensure that fire escapes remain free of smoke

Set point in temperature 
The VLT® HVAC Drive calculates the actual room temperature from the pressure in the cooling media and refines compressor operation accordingly without the need for additional software, sensors or controllers. This feature allows less expensive pressure sensors to be used.

Pipe Fill Mode
Enables controlled (closed loop) filling of pipes. Prevents water hammering, bursting water pipes or blowing off sprinkler heads.  End of Pump Curve detects breaks and leakage
The feature detects breaks and leakage. End of curve triggers an alarm, shuts off the pump, or performs another user defined action.

Dry Pump Protection lowers maintenance costs 
The VLT® HVAC Drive constantly evaluates the condition of the pump, based on internal frequency/power measurements. 


Standard cascade controller
The in-built cascade controller controls up to three pumps with fixed lead pump. 

Motor Alternation
This built-in logic controls alternation between two pumps in duty/stand-by applications. Motion of the stand-by pump prevents sticking of the pump. An internal timer assures equal usage of the pumps.

Flow compensation
The flow compensation feature reduces the pressure set point according to the flow - which saves energy. 

Initial/Final Ramp
The initial ramp provides fast acceleration of pumps to minimum speed, from where the normal ramp takes over. This prevents damage on thrust and bearings. Sensor less Pressure or Flow Control 

Safety
The VLT® HVAC Drive can optionally be delivered with the safe stop functionality suitable for category 3 installations according to EN 954-1. This feature prevents the drive from starting unintended.

Features and benefits



Enclosures 
The drive meets requirements for enclosure class IP 20/Chassis. Optional IP21/NEMA 1, IP55/NEMA 12, IP 54/NEMA12 or IP66 NEMA 4X.

 Smart logic controller
The VLT® AutomationDrive features logic control functions and a sequence control based on events and actions.

Safety 
The drive is delivered as standard with the Safe Torque Off (Safe Stop) function in compliance with EN ISO 13849-1 Category 3 PL d and SIL 2 according to IEC 61508 low demand and high demand mode. The safety functions can be extended to include SS1, SLS, SMS, SSM, safe jog mode etc. with the VLT Safe Option MCB140 Series and VLT Safe Option MCB150 Series.

Hot pluggable LCP 
The Local Control Panel (LCP) can be plugged in or out during operation. Settings are easily transferred via the control panel from one drive to another or from a PC with set-up software.

 Intelligent heat management 
Cooling can take place in two ways to offer different sets of benefits. Forced convection cooling: A fan blows cold air through the cooling ribs of the aluminium base to remove heat. The channel is easily cleaned without touching electronics. Cold plate cooling: External cooling is possible through the back side of the aluminium base. Panel through mounting: Electronics inside cabinet - power heat sink outside cabinet. Duct cooling: Air from the control room – or from outside – cools the heat sink without contact to the electronics.

Product Range

0.37 - 75 kW (380 - 480 V)


Features and benefits



Enclosures 
The drive meets requirements for enclosure class IP 20/Chassis.

Smart logic controller
The VLT® AutomationDrive features logic control functions and a sequence control based on events and actions.

Hot pluggable LCP
The Local Control Panel (LCP) can be plugged in or out during operation. Settings are easily transferred via the control panel from one drive to another or from a PC with set-up software. 

Efficient heat management
A unique cooling concept ensures that there is no forced air flow over the electronics. This reduces the risk of downtime, while strengthening stability in daily operation. By preventing dust and particles from accumulating on the small internal components and legs, the risk of short circuits is significantly reduced, especially in humid environments.

Coated Printed Circuit Boards
High level 3C3 Printed Circuit Board (PCB) coating as standard provides higher reliability in harsh environments to prevent failures and downtime. The lifetime of the drive is also increased as a result of the IED61721-3-3 conformal coating.
55°C Working Temperature
VLT® AutomationDrive FC 360 is designed to operate at 45-50°C ambient temperature at full load (depending on model) and 55°C with derating. This means there is no need to install extra cooling equipment or oversize the drive,resulting in cost savings.

Easy Cleaning
An easy to remove fan of the drive makes it easy to keep dust from affecting the drive’s ventilation. 

Built-in Brake Chopper
A built-in brake chopper up to 22kW saves money and panel space.

Built-in DC choke
Reduced Harmonics reduces harmonics to less than 43% (ThiD) and significantly extends the lifetime of the DC capacitor.   

PM motor support
Support for non-salient permanent magnet motor up to 22 kW for better system efficiency.
