Product Description:

The EFC3600-0K40-3P4-PDA-7P-NNNN is a frequency converter developed by Bosch Rexroth Indramat for the EFC Frequency Converters series. The unit works as a variable-speed interface between the supply network and an AC motor, allowing precise adjustment of rotational speed and torque in automated machinery and conveyor lines. Within an installation, it converts fixed-frequency mains power into adjustable output for changing process demands. It is intended for pumps, fans, and small material-handling axes where energy savings and basic speed control are needed.

The drive has a motor power rating of 0.4 kW, which suits compact motor loads in light industrial service. The input section accepts 400 V (AC 380–480 V -15% / +10%), so the unit can continue operating across common line-voltage variation. Regulation uses Enhanced V/Hz control, which maintains a consistent volts-per-hertz ratio for stable torque output over the operating range. Internally, the controller uses Flex-Control with Standard I/O, providing connections for analog references, digital commands, and one relay output. The built-in EMC filter is rated Class C3 for industrial areas, which suits industrial installations that may use longer motor cables. The enclosure has an IP20 protection class, which helps prevent accidental contact with live parts but is not sealed against liquids.

The housing uses Frame Size B, which helps the drive fit compact control cabinets while matching the mechanical layout used in this product range. Power is supplied through three-phase power, allowing balanced current draw at the input. Local operation uses a standard LCD display with potentiometer; the screen shows parameter values, and the dial allows direct speed adjustment from the front of the unit. This front interface supports routine monitoring and simple local changes without requiring separate external controls.
