Altivar Easy 310 drive is a frequency inverter for three-phase 380-460Vac asynchronous motors rated from 0.37kW / 0.5HP to 11kW / 15HP.
The compact size of this drive / its robust design / its ease of installation based on the principle of Plug & Play / its integrated functions and macro configuration make it particularly suitable for applications involving industrial machines and certain consumer machines.
By taking account of the constraints governing installation and use at the product design stage we have been able to offer a reliable / cost-effective solution to manufacturers of compact machines (OEMs).
The Altivar Easy 310 has been developed with no compromise on quality. The components are designed to last 10 years.

The Altivar Easy 310 drive incorporates functions that are suitable for the most common applications
- Textile machine
- Machine tools
- Wood making machine
- Material handling
- Packaging and printing machines
- Ceramic machine

In addition to the functions usually available on this type of drive the Altivar Easy 310 drive also features the following
- Motor control functions
-- standard / performance and pump/fan motor control profiles
-- Cooling fan thermal control
-- Switching frequency management
-- Boost torque
-- Motor noise reduction
-- Current limitation
-- Auto DC injection

- Application functions
-- Frequency skip
-- Preset speeds
-- PID regulator
-- S ramp / U ramp / ramp switching
-- Jog operation
-- +/- speed around reference
-- Freewheel stop / fast stop
-- Automatic catching a spinning load with speed detection and automatic restart

- Control functions
-- Channel configuration - separate mode or not
-- Reference channel selection
-- Reverse inhibition
-- Force local control
-- Store customer parameter settings
- Protection and maintenance functions
-- Protection of the installation by means of underload and overload detection

- Maintenance functions
-- HMI password
-- Configuring the logic and analog I/O
-- Configuring how the parameters are displayed
-- Viewing the state of the logic inputs on the drive display
-- Key parameters display (drive power on / Fan time / Process elapsed time)
-- The last 4 fault display / error log / etc.

The entire range conforms to international standards IEC/EN 61800-5-1 and IEC/EN 61800-3 and has been developed to meet the requirements of directives regarding the protection of the environment (RoHS / WEEE).
Owing to its innovated air flow design and to its thicker coating which avoids polluting PCB. The range can be used in the harshest environments.
It can withstand a 55°C / 131°F ambient air temperature around the device without derating.
Its degree of protection is IP20 (IP41 on top of the product).

The Altivar Easy 310 has been designed with an increased adaptability to different motors and various tough loads. One of its main quality is its torque capacity for starting and braking.
- Braking capacity
-- over 80% of the rated motor torque without braking resistor
-- 150% of the rated motor torque with braking resistor
- Torque capacity
-- starting torque 150% at 3Hz
-- over torque 150% to 170% depending on model.

The Altivar Easy 310 drive integrates as standard the Modbus communication protocol which can be accessed via the RJ45 connector located on the underside of the drive 1 with a 2-wire RS 485 physical interface.
To communicate on the network the Altivar Easy 310 speed drive uses the Modbus RTU transmission mode.
Logic inputs can be configured as source or sink by software -- compatible with many PLCs.
The Altivar Easy 310 drives can easily and quickly be installed as
- they are easy and quick to wire due to their Plug & Play concept
- they can be identified on the front panel.
- they can be mounted side by side to save cabinet space.
- power terminal and connection labels are easily identified and differentiated.
- a connection guideline is shown inside the front door.

The Altivar Easy 310 drive can be connected to a remote display terminal available as an option. This terminal can be mounted on an enclosure door with IP54 or IP65 degree of protection.
The maximum operating temperature is 50°C / 122°F. It provides access to the same functions as the Human-Machine interface.
The Simple Loader tool enables one powered-up drive's configuration to be duplicated on another powered-up drive. Operation is very simple.
The Multi-Loader tool enables configurations from a PC or drive to be copied and duplicated on another drive. The drives do not need to be powered up.
The configuration can be loaded onto the drive without taking it out of its packaging.
A warning is sent by the drive to the user when it is necessary to clean heat sink or replace cooling fan. This fan which is the only wearing part can be changed without the need for any tool.
The security of the system is ensured by an access code allowing authorized people to configure applications and settings in Configuration mode. Simple users are only allowed to use the Monitoring mode (parameters display).
