These drives are installed in control cabinets deployed for automation systems. They help to operate the manufacturer’s AC synchronous motors at different speeds by keeping control over the frequency of the input voltage. KDF variable frequency drives are usually positioned between KVR power supplies and TDM servo drives from the same manufacturer.

The high-quality and high-performance variable frequency drives are characterized by various features like a maximum speed of 8,000 RPM, unrestricted four-speed operation and position control. Indramat KDF variable frequency drives can control motors with up to 25 HP output power. They make use of digital velocity loop processors and analog velocity commands to support their operation. The drives are widely used in OEM machinery and HVAC equipment, as well as for applications that require ultra-compact solutions. These variable frequency drives have a DC bus voltage rating of 300 VDC. We have expertise in building obsolete parts that are not easily available and can help you with the right drive for your application.

• KDF variable frequency drives incorporate heatsink blowers for cooling by means of a forced air cooling action.
• The Indramat drives encompass analog differential inputs that allow them to be operated by any control system.
• The KDF range of variable frequency drives is equipped with a torque limit adjustability feature that allows accurate control over torque and torque restriction at certain levels.
• The variable frequency drives help in sustaining, decreasing or increasing the motor speed in an energy-efficient manner and also bringing the associated motors to a halt.
• The drives can be used to implement high-quality and precise motor solutions for efficient machine automation.

KDF variable frequency drives help in reducing the energy consumption of the related motors by controlling their performance. The variable frequency drives convert the input power to adjustable voltage sources and frequencies to control the speed of AC induction motors. This speed can be controlled during the start and stop cycle as well as all through the running cycle.

The variable frequency drives encompass three parts: a controller, a feedback device and an inverter. The drives help in cutting down noise emissions and maintenance costs. Indramat KLM drives can be controlled using a programmable logic controller.
