Product Description:

The EFC3610-7K50-3P4-MDA-7P-00002-NNNN is a compact frequency converter produced by Bosch Rexroth Indramat within the EFC Frequency Converters series and the EFC 3610 model range. As a variable-speed drive, it modulates the AC supply to an attached motor so industrial machinery can accelerate, decelerate, and hold setpoints without mechanical gear changes. This supports steady operation in equipment that needs adjustable motor speed during normal production. The unit belongs to product line 02 and uses a standard control configuration, which gives the drive a familiar interface for motor axes, pumps, and similar automation duties.

For heavy-duty tasks, it delivers 7.5 kW of output and draws power from a three-phase mains supply rated at 400 V AC (380 to 480 V, -15% to +10%). The power section is designed for three-phase power, allowing balanced loading on industrial supply networks. Regulation is handled by Enhanced V/Hz control, which maintains a fixed voltage-to-frequency relationship to help keep motor flux stable across speed changes. An integrated EMC filter classified for industrial area, class C3 limits conducted noise so the converter can share cabinets with sensitive control hardware. User interaction is provided through a Standard LCD display with potentiometer, which allows local setpoint adjustment without external tools. These functions are managed by the Flex-Control section, which provides standard I/O terminals for run, fault, and speed reference signals.

The mechanical package corresponds to Frame Size E, so the heat sink dimensions fit common panel layouts and allow side-by-side mounting in 200 mm deep enclosures. Protection is limited to IP20, which means the unit must be installed inside a cabinet so live parts are not exposed during operation. Communication with higher-level controllers is available through Modbus, giving access to parameter changes and start-stop commands over a two-wire serial link. No onboard safety function is included, so emergency stop logic must be handled externally through the digital inputs or by using a separate safe torque off module.
