What does this variable speed drive do in a motor control system?

It controls the speed and torque of compatible AC motors by varying the output frequency and voltage, enabling smoother starting, controlled acceleration/deceleration, and energy-efficient operation on industrial machines. This model supports an output frequency range of 0.1 to 599 Hz.

What supply voltage and phase does it require?

It is designed for a 3-phase supply in the 380 to 480 V range (permitted supply limits are 323 to 528 V), with a supply frequency of 50/60 Hz (network frequency limits 47.5 to 63 Hz).

What motor power rating is it intended for?

It is rated for 11 kW (15 hp) motors on a 380 to 480 V, 3-phase supply, making it suitable for complex, higher-power machinery applications.

What output current can I expect from this drive?

Nominal output current is 21 A at 4 kHz and 460 V (3-phase), or 27.7 A at 4 kHz and 380 V (3-phase). It also supports higher transient current for short durations (41.6 A for 60 s and 45.7 A for 2 s).

Which motor types can it run?

It is intended for both asynchronous and synchronous motors, with multiple control profiles including sensorless flux vector control and voltage/frequency modes. Closed-loop operation is possible when used with an encoder interface option.

What communications are available as standard?

It includes Modbus and CANopen communication. Modbus uses a 2-wire RS-485 physical interface with RTU framing, and CANopen supports multiple baud rates up to 1 Mbps.

Where are the communication connectors located and what type are they?

It provides RJ45 connectivity for Modbus (one on the front face and one on the terminal area) and a CANopen connection via a male SUB-D 9 presented on an RJ45-style interface.

How many I/O points does it have built in?

Built-in I/O includes 2 analogue inputs, 1 analogue output, 7 discrete inputs, and 2 relay-type discrete outputs. The analogue and discrete functions are configurable to suit typical speed reference and control schemes.

What are the analogue signal ranges supported?

Analogue inputs include one differential voltage input (±10 V) and one input that can be set for either 0–20 mA or 0–10 V. The analogue output can be set for either 0–20 mA, 0–10 V, or a 10 V logic-style output (limited current).

What switching frequency does it use, and can it be adjusted?

The nominal switching frequency is 4 kHz. It is adjustable from 1 to 16 kHz, with derating required in certain higher-frequency operating conditions.

What are the maximum recommended motor cable lengths?

Maximum motor cable length is 50 metres with shielded cable, or 100 metres with unshielded cable (application conditions may require additional measures for best results).

What are the key installation and mounting recommendations?

It should be installed vertically (within ±10°), away from heat sources, and with adequate free space to allow airflow from bottom to top. In enclosures, ensure ventilation openings (and fans if required) provide airflow at least equal to the drive’s internal fans.

What IP protection levels are associated with this drive?

It is commonly specified with IP21 overall, with additional ratings depending on configuration (for example IP41 on the upper part and IP54 on the lower part). Removing the protective blanking cover from the top reduces the upper protection to IP20.

What operating environment limits should be considered?

Typical operating ambient temperature is -10 to 50°C without derating, relative humidity 5–95% (without condensation), and altitude up to 1000 m without derating. From 1000 to 3000 m, current derates by 1% per 100 m.

What are the physical dimensions and approximate weight for panel layout planning?

Approximate dimensions are 295 mm (H) x 210 mm (W) x 213 mm (D), with a net weight of about 8 kg. Allow additional space for wiring access and cooling clearance.

Does it include an EMC filter?

Yes. This drive includes an integrated EMC filter, which can help simplify compliance planning in many industrial installations.
