Product Description:

The EFC3610-1K50-1P2-MDA-NN-NNNNN-NNNN is a frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series. This unit is used in drive panels to regulate induction motor speed for industrial automation tasks such as pumps, fans, and small conveyors. By varying the output frequency, it allows the motor to match torque to process demand more closely, which can reduce unnecessary power use during partial-load operation. It also helps support smoother acceleration and deceleration in routine machine duty.

The converter connects to a mains supply of AC 200–240 V (±10%) and operates on a single phase circuit, which suits light-duty control cabinets where three-phase input power is not available. In heavy-duty mode, it delivers 1.5 kW of motor power while remaining within an enclosure rating of IP20, so it provides basic touch protection and must be mounted inside a protected cabinet. Command and monitoring data are exchanged through Modbus, allowing communication with PLCs for speed reference, status reporting, and parameter access. This arrangement supports straightforward integration with standard automation networks used for small motor-control applications.

Housed in frame size C, the unit follows product line 02 and uses Flex-Control with Standard I/O, which provides fixed terminal blocks for digital and analog signals. Its internal control method is enhanced V/Hz control, which improves open-loop torque behavior across the speed range and suits general-purpose motor operation where simple speed regulation is needed. For conducted emissions, it uses an EMC filter rated for industrial area, class C3. No integrated display is present, and a dust cover fills the front slot. The converter also has no built-in safety function, so any required safe-torque-off function must be provided by external safety hardware.
