Bosch Rexroth VFC3610 Frequency Converter

Variable-Frequency Control for Finishing Machines

The Bosch Rexroth VFC3610 can be assessed for a compatible vibratory polishing machine drive. Frequency control changes drive speed; the resulting load movement also depends on the motor arrangement, eccentric settings, machine construction, and working load.

Suitable drive configurations can also be reviewed for a centrifugal barrel machine, rotary barrel tumbler, or centrifugal disc finisher. Confirm the permitted operating range for the actual machine before changing speed.

Mechanical and Operating Features to Specify

• Compact modular cabinet arrangement, side-by-side installation, and DIN-rail mounting where supported
• LED operating panel; LCD panel and Bluetooth adapter where supported by the selected version
• Removable panel, parameter-copy function, and cabinet-door installation
• Pluggable I/O section and the specified communication or expansion options; the range description lists two expansion slots
• Cooling-fan arrangement for the selected rating; the range description identifies a detachable fan above 1.5 kW
• Braking configuration selected for the duty; a built-in unit is described for ratings of 22 kW or less
• PNP/NPN wiring as specified for the selected control terminals

Control Functions and Interfaces

The range description lists heavy/light-duty selection, low-frequency oscillation suppression, speed-tracking start, reverse disable, low-voltage ride-through, wobble-frequency operation, sleep/wake functions, a counter, and an energy-use calculation function. Confirm the available functions for the ordered converter, power rating, firmware, and options.

• Pulse input: 50 kHz; pulse output: 32 kHz, as listed for the described range
• 24 V auxiliary supply: maximum 100 mA for the described ratings within 22 kW
• Modbus RTU and the specified I/O configuration
• Commissioning and software-update arrangement, including the listed mini-USB connection where supported

Check the rated input voltage, phase, frequency, output current, motor data, and braking duty against the converter nameplate and manual. Parameter settings do not make an unsuitable mains supply compatible. Provide the machine and motor details, local supply, control requirements, and desired operating range for a drive review.
