Franklin Control Systems’ Q-link Variable Frequency Drive provides a unique user experience through intuitive smartphone operation. The drive was designed from the ground up for HVAC applications and users in that industry, with streamlined start-up, reporting, and support. The Q-link provides an array of inputs and outputs including damper control. The Q-link uses R3 filtering – a sophisticated filtering algorithm – to reduce harmonic distortion and provide equivalent performance to an AC line reactor, without the added cost. Native communications include BACnet and Modbus. The Q-link will also be offered in a Smart Bypass version, which offers advanced Smartstart protection, native communications, and pass-through I/O while in bypass mode.
The Q-link VFD is Bluetooth® enabled. Once a smartphone is paired with a Q-link VFD, users are guided through a series of configurations pertaining to application, motor specs, communications, input terminals, and more. When the drive has been configured, the user may bump the motor or run it for testing and balancing purposes, all remotely through the app. Custom configurations can be saved and applied to additional units when commissioning multiple drives.
Commissioning reports can easily be generated and emailed via the Q-link app and settings and running values from the VFD are automatically populated. General project information can be filled out and photos can be taken in-app and attached to the report. When a commissioning report is complete, it can be signed and emailed in the app.
Faults and settings changes are logged and organized by date. In the Q-link app, in-depth fault explanations are accompanied by specific trouble shooting tips and run condition details at the time of the fault. If live support is needed, a pre-call report containing the VFD unit’s current settings and logs can easily be sent via the app. This report reduces troubleshooting time by eliminating the need for the user to scroll through and read parameters over the phone.
The Q-link Horsepower Rated VFD allows distributors to stock less inventory and increase inventory turns due to its versatility. As the name implies, the drive is UL approved to be rated for motor horsepower rather than current. Available up to 7.5 hp, each model will cover a motor from 200 to 480 V. This eliminates the chances that a drive will arrive on the jobsite with incorrect voltage.
