VFD Accessories

VFD accessories include the operator keypads, remote display panels, communication modules, option cards, and mounting hardware that extend and support the functionality of installed variable frequency drives. PLC Direct supplies VFD accessories from leading automation manufacturers as surplus, sealed, refurbished, and used hardware, supporting the replacement and maintenance of installed drive systems when a failed or missing accessory prevents operation, parameter access, or fieldbus communication.

Where Are VFD Accessories Used in Industrial Environments?

VFD accessories are installed wherever variable frequency drives are in service, providing the operator interface, network communication, and enclosure integration hardware that the drive installation depends on to function correctly within the wider control system. Drive keypads, communication modules, and mounting kits are specific to the drive family they support and must be sourced by exact part number when replacement is required.

Facilities and operations that depend on VFD accessories include:

Manufacturing plants where SINAMICS G120 VFD operator panels (IOP-2) mounted on control cabinet doors provide local parameter access and fault diagnostics without opening the drive enclosure.

Water and wastewater treatment facilities where drive communication modules connect installed Altivar drives to SCADA systems via EtherNet/IP or Modbus TCP/IP for remote monitoring and control at distributed pump stations.

Food and beverage processing operations where VFD remote keypads on Yaskawa V1000 and A1000 drives allow operators to adjust speed references and monitor drive status from outside a sealed washdown enclosure.

Mining and heavy industrial installations where VFD option cards extend installed drives with additional I/O, encoder feedback, or fieldbus interfaces required by the process control system.

OEM machine builders and maintenance workshops sourcing drive accessory replacement parts to restore installed VFD configurations to the original specification after a keypad or communication module failure.

When a VFD keypad or accessory fails, sourcing the correct replacement by exact part number restores drive operability without requiring drive replacement or control system reconfiguration.

Which Brands of VFD Accessories Does PLC Direct Stock?

PLC Direct stocks VFD accessories, including operator panels, communication modules, and mounting hardware from major automation manufacturers.

Siemens SINAMICS G120 Operator Panels and Mounting Hardware: The IOP-2 intelligent operator panel and door mounting kit for SINAMICS G120, G120C, and G120D drives provide IP55 local operator interface and remote panel mounting capability.

Yaskawa JVOP Series Operator Keypads: The JVOP series keypads and operator interfaces cover current and legacy Yaskawa inverter families for local parameter access and drive monitoring.

Schneider Electric VW3A Series Communication Modules and Accessories: VW3A series EtherNet/IP and CANopen communication modules and UL Type 1 conformity kits extend communication and enclosure compliance for Altivar 61 and Altivar 71 drives.

All VFD accessories at PLC Direct are available as surplus sealed, refurbished, and used, depending on current inventory.

What Should You Know Before Ordering VFD Accessories?

Hardware condition options: PLC Direct supplies VFD accessories as surplus sealed, refurbished, and used hardware. Surplus sealed accessories are factory-sealed stock in original packaging; used hardware is inspected prior to listing and carries the same 1-year PLC Direct warranty as all other condition grades.

Compatibility and part identification: VFD accessories, such as operator keypads and communication modules, are specific to the drive family and, in many cases, the drive firmware version. A replacement must match the exact part number of the original accessory and be confirmed compatible with the installed drive model before ordering. For communication modules, the protocol supported is encoded in the part number and must match the fieldbus used by the installed control system, substituting a PROFIBUS module for an EtherNet/IP module, for example, requires reconfiguration of the control system, not just hardware replacement.

Warranty: All VFD accessories and hardware purchased from PLC Direct carry a standard 1-year warranty covering defects and functionality, applicable to surplus sealed, refurbished, and used products.

PLC Direct supplies VFD accessories and hardware for replacement and maintenance purposes and does not provide system design, programming, or integration services.

Frequently Asked Questions

Most variable frequency drives can be operated without a locally mounted keypad once commissioned, as control commands and speed references are typically provided via the fieldbus or hardwired I/O terminals. The keypad is required for local parameter access, fault reset, and diagnostics; without it, fault codes can only be read through a connected fieldbus or PC tool, which may not be available in all maintenance situations.

A basic operator panel provides numeric parameter display and entry via a simple keypad, while an intelligent VFD operator panel, such as the Siemens IOP-2, offers a graphical display, startup wizards, multilingual menus, and parameter backup and restore functions. The intelligent panel simplifies commissioning and fault diagnosis and is the preferred option where drives are configured locally or maintained by personnel who are not drive specialists.

Replacing a VFD keypad does not affect the drive's stored parameters, as they are stored in the drive's non-volatile memory, not in the panel. Some keypads offer parameter backup functions that store a copy of the drive configuration on the panel; if this backup is used as the primary parameter record, that copy is lost when the panel is replaced, so it's important to confirm whether a backup exists elsewhere before swapping the panel.

In most cases, no. VFD option cards and communication modules are designed for specific drive platforms and are not interchangeable across generations, even within the same manufacturer's product range. Schneider Electric VW3A modules, for example, are specified by drive family compatibility in the part number; Siemens SINAMICS option modules differ between the G120 and S120 platforms. Always verify the drive model compatibility listed in the accessory part number description before ordering.

The replacement drive communication module must match the protocol required by the control system, EtherNet/IP, PROFIBUS, CANopen, or Modbus TCP/IP, and must be confirmed compatible with the specific drive model and firmware version in the installed equipment. The module's part number encodes the protocol, so confirming both the installed drive model and the network protocol in use before ordering avoids receiving a module that physically fits but cannot communicate on the installed network.
