Product Information

Product Family: VLT | Series: VLT 6000S / VLT 8000S

The Danfoss 175Z7804 is a Local Control Panel (LCP) keypad and HMI operator interface for Danfoss VLT 6000S and VLT 8000S frequency inverters. It provides local programming, operation and monitoring through an LCD display that shows real-time drive parameters such as output frequency and motor current, together with status notifications, warnings, alarms and alphanumeric fault descriptions. The keypad is front-mounted and has an IP65 front-mounted protection rating.

This VLT LCP keypad uses a direct plug-in installation and communicates with the drive main control board through an internal multi-pin connector. During a replacement or commissioning task, drive parameters can be uploaded, downloaded and transferred between compatible drives. For remote installation, the 175Z0850 remote-mounting kit with 3 m cable, the 175Z7802 IP54 remote-mounting kit with 3 m cable and the 175Z0929 3 m LCP cable are compatible accessories.

For troubleshooting, the LCD provides access to operating values, warnings, alarms and alphanumeric fault descriptions, while the LED indicators show drive On, Warning and Alarm conditions. Before fitting a spare, confirm that the drive belongs to the VLT 6000S or VLT 8000S series and check the internal multi-pin connection and mounting arrangement. The 175Z7804 is a discontinued Danfoss replacement component for maintaining compatible legacy drive installations.

Programming and Configuration

The 175Z7804 provides local programming and monitoring for compatible Danfoss VLT 6000S and VLT 8000S frequency inverters. The LCD keypad gives access to drive parameters, operating values, warnings, alarms and alphanumeric fault descriptions.

Parameter backup and transfer are supported between compatible drives. A replacement keypad or drive commissioning task can therefore include uploading parameters from one compatible drive and downloading or transferring them to another.

Before commissioning, match the replacement to the VLT 6000S or VLT 8000S drive series and confirm the direct plug-in connection to the drive control board.

Communication and System Integration

The keypad communicates with the VFD main control board through an internal multi-pin plug-in connector. Its direct plug-in, front-mounted arrangement is intended for compatible Danfoss VLT 6000S and VLT 8000S frequency inverters.

Remote installation is supported with the 175Z0850 remote-mounting kit with 3 m cable, the 175Z7802 IP54 remote-mounting kit with 3 m cable, or the 175Z0929 3 m LCP cable. These accessories allow the LCP interface to be positioned separately from the drive when the installation requires remote mounting.

The 175Z7804 should be matched by drive series and connection arrangement before installation. It is intended for VLT 6000S and VLT 8000S systems rather than as a general keypad for other VLT drive families.

Diagnostics and Status Indication

The LCD displays real-time drive parameters including output frequency and motor current. It also presents status notifications, warnings, alarms and alphanumeric fault descriptions for local assessment of the connected drive.

Visual LED indications show the drive On, Warning and Alarm conditions. During troubleshooting, use the displayed operating values and status indications together with a check of the drive series, keypad seating and internal multi-pin connection.

Replacement and Spare Part Considerations

For a replacement, the key compatibility check is the drive series: the Danfoss 175Z7804 is intended for VLT 6000S and VLT 8000S frequency inverters. Confirm the part number, front-mounted installation and internal multi-pin plug-in connection before fitting the spare.

The keypad supports parameter upload, download and transfer between compatible drives. Include parameter transfer in the commissioning procedure when the replacement is being used to restore local programming, monitoring or drive setup.

The 175Z7804 is discontinued and is used as a maintenance replacement for compatible legacy drive installations. The 175Z0850, 175Z7802 and 175Z0929 accessories support remote LCP installation with the stated cable arrangements.
