Description

This variable speed drive is engineered for complex machines requiring reliable motor control and specialized safety features. Operating within a rated supply voltage range of 380...500 V alternating current (AC) across 3 phases, it delivers a nominal output current of 14.3 A and supporting a motor power of 5.5 kW designated for heavy duty operations.

The unit incorporates extensive input and output options, featuring 7 discrete inputs, 3 discrete outputs, 3 analogue inputs, and 1 analogue output. It integrates a Class C2 EMC filter and offers embedded communication over Modbus serial and CANopen. For enhanced application compatibility, optional communication modules such as EtherCAT, Profibus DP V1, PROFINET, Ethernet Powerlink, EtherNet/IP, and DeviceNet can be utilized. Built-in functional safety capabilities include Safe torque off (STO), Safe Stop 1 (SS1), and Safely Limited Speed (SLS).

Features

Flexible Control Profiles: Supports multiple asynchronous motor control profiles (Voltage/Frequency ratios in 2 or 5 points, quadratic U/f for Energy Saving, and flux vector control without sensor) along with synchronous vector control without sensor.
Integrated Safety Capabilities: Embedded with functional safety capabilities, explicitly featuring Safe torque off (STO), Safe Stop 1 (SS1), and Safely Limited Speed (SLS).
Dynamic Torque Performance: Delivers a transient overtorque capacity of 170...200% of the nominal motor torque.
Comprehensive Protective Braking: Equipped with an integrated brake chopper and supports braking to standstill via DC injection.
Four-Quadrant Operation: Supports full 4 quadrant operation for driving and braking in both forward and reverse directions.
Adaptable Ramp Profiles: Provides customizable acceleration and deceleration ramps including linear, U, S, CUS, ramp switching, automatic stop with DC injection, and ramp adaptation.
Automatic Slip Compensation: Provides load-independent automatic motor slip compensation, which is adjustable from 0...300%.

Installation Guidelines

Orientation: Mount the drive vertically. Deflections must remain within +/- 10 degrees from the true vertical position.
Ventilation and Cooling: Ensure unimpeded airflow around the chassis. The internal cooling fan requires a minimum air volume flow of 60 m3/h.
Thermal Derating: For operational environments between -10 degC and 50 degC, no derating is necessary. If the ambient operating temperature rises between 50 degC and 60 degC, an appropriate technical derating factor must be applied.
Environmental Enclosure: The unit carries an IP20 rating and must be mounted inside an industrial enclosure providing protection against airborne contaminants, conforming to pollution degree 2 limits.

FAQ

What embedded communication interfaces are immediately accessible on this module?

The variable speed drive comes standard with an integrated slave CANopen and Modbus serial interface protocol via its primary communication port.
Can this unit be adapted to other industrial fieldbus networks like PROFINET or EtherCAT?

Yes. Communication modules for external networking architectures including PROFINET, EtherCAT, Profibus DP V1, Ethernet Powerlink, EtherNet/IP, and DeviceNet are fully compatible via option card slots.
What is the default pulse configuration for the discrete logic input terminals?

The unit features 7 discrete inputs where terminal DI5 can be explicitly programmed to handle pulse configurations up to 30 kHz at 24 V DC.
Does this system require an external braking chopper for heavy-duty overhauling loads?

No. An internal brake chopper is integrated directly within the unit, allowing for energy absorption and DC injection braking to standstill.
What thermal conditions must be maintained during active operation?

The operating range spans -10 degC up to 50 degC without losing performance metrics. Operation up to 60 degC is permissible provided a specific derating factor is implemente
