Altivar 12 0.75 kW Drive

The ATV12H075M2 is sized for motors with a rated power of:

• Motor power: 0.75 kW.
• Equivalent power: 1 HP.
• Rated output current: 4.2 A.
• Output voltage: up to 240 V AC.

It allows the motor speed to be adapted to the actual needs of the machine, avoiding the need for the motor to operate permanently at rated speed when the process does not require it.

Single-phase input and three-phase motor output

An important feature of this reference is that it has a single-phase 200 to 240 V AC supply, while being ready to power a 200/240 V three-phase motor.

This makes it possible to control a compatible three-phase motor from a single-phase supply installation, provided that the motor power, voltage, and current are within the drive's specifications.

The permitted supply voltage is:

• 200-240 V AC single-phase.
• Voltage tolerance: -15% / +10%.
• Supply frequency: 50/60 Hz ±5%.

Rated output current of 4.2 A

The Schneider Electric ATV12H075M2 provides a continuous rated output current of 4.2 A at a switching frequency of 4 kHz.

According to the Altivar 12 technical documentation, this reference also indicates transient capacities of approximately:

• 6.3 A for 60 seconds.
• 6.9 A for 2 seconds.

These capacities make it possible to respond to certain brief increases in torque demand during machine start-up or operation.

Adjustable output frequency from 0.5 to 400 Hz

The drive allows the output frequency to be adjusted between 0.5 and 400 Hz, offering a wide range for motor speed control.

The nominal and maximum frequency must be configured according to the motor's electrical and mechanical characteristics. It must not be used at a speed higher than that allowed by the motor manufacturer and the driven machine.

Sensorless vector control

The Altivar 12 offers different control profiles for asynchronous motors, including:

• Sensorless flux vector control.
• V/F voltage/frequency control.
• Quadratic voltage/frequency control.

Sensorless vector control improves motor performance at low speeds without the need to install an external encoder.

Transient torque boost up to 170%

Schneider Electric specifies a transient torque boost of approximately 150 to 170% of the motor's rated torque, depending on the drive power and the connected motor.

This torque reserve can be especially useful during acceleration or when there are brief load increases.

Integrated PID regulation

The ATV12H075M2 incorporates an adjustable PID controller, making it suitable for applications where an automatic process variable must be maintained.

It can be used, for example, in systems for:

• Pressure control.
• Flow control.
• Ventilation.
• Extraction.
• Pumping.
• Simple HVAC processes.

Using feedback from a compatible sensor, the drive can modify motor speed to maintain the configured setpoint.

Catch on the Fly function

The Altivar 12 includes the function known as Catch on the Fly, designed to regain control of a motor that is still rotating.

This function is useful, for example, in fans where the motor may continue spinning by inertia after stopping or due to air movement.

Integrated Modbus communication

The Schneider Electric ATV12H075M2 includes Modbus serial communication via a 2-wire RS-485 interface as standard.

It features an RJ45 connector and supports configurable communication speeds of:

• 9.6 kbit/s.
• 19.2 kbit/s.
• 38.4 kbit/s.

The Modbus protocol makes it possible to integrate the drive into certain automation and monitoring systems to read parameters, statuses, or setpoints and modify compatible settings.

Inputs and outputs for automation

The ATV12 includes different inputs and outputs for connecting control signals, sensors, and external devices:

• 4 digital inputs.
• 2 digital outputs.
• 1 analog input.
• 1 analog output.
• 1 relay output.

These connections make it possible to configure functions such as run, stop, direction change, speed selection, external setpoints, and status signaling.

Configurable acceleration and deceleration ramps

The drive allows acceleration and deceleration ramps to be set, avoiding abrupt motor starts and stops.

Progressive acceleration can reduce mechanical stress on transmissions, couplings, belts, and other machine components, as well as limit the current peaks associated with direct starting.

Adjustable switching frequency

The switching frequency can be configured between approximately 2 and 16 kHz, with a factory nominal value of 4 kHz.

Higher frequencies may require current derating according to the conditions specified by Schneider Electric.

DC injection braking

The Altivar 12 allows braking to standstill by DC injection, enabling controlled motor stopping in certain applications.

This reference does not include a braking chopper, so this characteristic must be taken into account in applications with strong regenerative braking requirements.

Integrated EMC filter

The ATV12H075M2 incorporates an integrated EMC filter, intended to limit conducted electromagnetic interference generated by the drive when the installation is carried out according to Schneider Electric's recommendations.

The manufacturer specifies conducted emission performance compatible with IEC 61800-3 under the corresponding installation conditions, including the use of shielded motor cable when necessary.

Integrated electronic protections

The drive includes different protection and monitoring functions to help protect both the equipment itself and the connected motor.

The main protections include:

• Supply overvoltage.
• Supply undervoltage.
• Overcurrent between output phases and earth.
• Motor phase-to-phase short circuit.
• Drive overtemperature protection.
• Electronic motor thermal protection through continuous I²t calculation.

These functions do not eliminate the need to install the external electrical protections required for the supply circuit.

Electronic motor thermal protection

The Altivar 12 continuously calculates the motor thermal load using an I²t model, providing electronic protection against certain overload conditions.

For this function to operate correctly, the motor nameplate data must be entered and configured properly.

Applications of the Altivar 12 ATV12H075M2

Schneider Electric designs the Altivar 12 range for simple machines, commercial equipment, and HVAC applications. Typical uses include:

• Pumps.

Energy savings in pumps and fans

Speed control makes it possible to adapt motor consumption to the actual process demand. This is especially interesting in pumps and fans, where reducing speed when maximum flow is not required can significantly lower energy consumption.

Schneider Electric indicates that power and torque optimization of the Altivar 12 for certain ventilation and pumping applications can help achieve energy savings of up to approximately 30% under suitable operating conditions.

IP20 protection rating

The drive has an IP20 protection rating and is primarily designed for installation inside an electrical cabinet or panel.

It must not be installed directly exposed to dust, water, or other environmental conditions incompatible with this protection rating.
