Trane TR170 VFD Details

The Trane TR170 VFD is a sophisticated frequency converter specifically engineered for Heating, Ventilation, and Air-Conditioning (HVAC) applications. It operates primarily in variable torque mode, making it ideally suited for controlling fans and pumps with optimal efficiency and reduced energy consumption. This focus allows for tailored performance in dynamic building environments, ensuring precise control over air and fluid movement.

User interaction with the TR170 VFD is facilitated through several optional interfaces, including the Numerical Local Control Panel (LCP 21) and the Graphical Local Control Panel (GLCP or LCP 102). These panels enable technicians to easily adapt parameter settings, monitor operational status, and review historical fault logs, offering both visual feedback and hands-on control for commissioning and maintenance tasks.

Internally, the TR170 VFD features a robust control logic section, powered by a microprocessor, which oversees and regulates all functions. This section utilizes a PROM for programmable options and an EEPROM to securely store user-defined parameters, ensuring flexibility and data retention even during power outages. This design allows for customization to meet specific application demands efficiently.

The device supports a variety of input and output signals for comprehensive control and monitoring. It can receive digital (0–24 V DC) and analog (0–10 V DC or 0/4–20 mA) input signals from external sensors or controllers. These inputs dictate start/stop commands, speed references, and other operational adjustments, allowing the VFD to respond dynamically to system requirements.

Output signals from the TR170 VFD, available via the RS485 serial bus or specific terminals, provide critical data such as frequency, current, and torque to external systems. Additionally, configurable Form C relay outputs allow the VFD to control auxiliary equipment or report status, integrating seamlessly into broader building management systems. Proper wiring and parameter programming are crucial for these functionalities.

The internal operation includes a sophisticated power section, featuring a rectifier for AC-to-DC conversion, an intermediate DC link with DC coils and capacitor banks for voltage smoothing, and an inverter section equipped with IGBTs (Insulated Gate Bipolar Transistors) for precise motor control. These components work in sequence to convert input power into the variable frequency output required by the motor.

Furthermore, the TR170 VFD incorporates features like fan speed control based on internal temperature sensors, which helps in maintaining optimal operating conditions and extending component life. It also includes comprehensive protection mechanisms, such as short-circuit and overcurrent trips, ensuring safe operation and safeguarding the motor and the VFD itself from potential damage.

The design also emphasizes electromagnetic compatibility (EMC) through measures like RFI filters and proper grounding guidelines. These considerations are vital for preventing EMI (electromagnetic interference) that could disrupt sensitive electronic components, both within the VFD and in adjacent control systems, ensuring reliable performance in industrial and commercial environments.

Frequently Asked Questions (FAQs)

Can't find the answer you need? Here are some frequently asked questions about the Trane TR170 VFD, and we answer them below.


What is the primary application of the Trane TR170 VFD?
The Trane TR170 VFD is designed for Heating, Ventilation, and Air-Conditioning (HVAC) markets, operating in variable torque mode for fan and pump applications.

What should I do if the TR170 VFD display is dark, but the green power-on LED is lit?
If the green power-on LED is illuminated but the backlit display is dark, it indicates a defective LCP (Local Control Panel) that needs to be replaced.

What does an intermittent or flashing display on the TR170 VFD indicate?
An intermittent or flashing display, including the power LED, typically indicates that the internal Switch Mode Power Supply (SMPS) is shutting down due to an overload. This could be caused by improper control wiring or an internal fault.

Why might my TR170 VFD motor not run, and what status messages should I look for?
If the motor does not run, check for status messages like 'LCP Stop', 'Standby', 'Unit ready', 'Run OK, 0 Hz', or 'Off 1 (2 or 3)'. These indicate issues with start commands, references, or fieldbus communication.

How do I troubleshoot an 'Over Current' alarm (Alarm 13) on my Trane TR170 VFD?
An 'Over Current' alarm (Alarm 13) suggests the inverter peak current limit has been exceeded. Check if the motor shaft can be turned, ensure the motor size matches the frequency converter, and verify correct motor data (parameters 1-20 to 1-25).

What causes a 'Mains Phase Loss' alarm (Alarm 4) in the TR170 VFD?
A 'Mains Phase Loss' alarm (Alarm 4) occurs when a phase is missing on the supply side, or the mains voltage imbalance is too high. This can also indicate a fault in the input rectifier or line disturbances affecting the DC bus ripple.

What should I do if my TR170 VFD displays a 'DC overvoltage' alarm (Alarm 7)?
A 'DC overvoltage' alarm (Alarm 7) usually results from fast deceleration ramps with high inertia loads, causing regenerative energy to increase the DC-link voltage. Solutions include extending the ramp time, changing the ramp type, or enabling the overvoltage control function (parameter 2-17).

How can I ensure optimal motor control with the TR170 VFD?
For optimal motor control, accurately set motor parameters (power, voltage, frequency, current, nominal speed) in parameters 1-20 to 1-25. Performing the Automatic Motor Adaption (AMA) function (parameter 1-29) also fine-tunes the VFD to the motor's electrical characteristics.

What are the essential safety precautions when servicing the Trane TR170 VFD?
Always disconnect mains power and wait for DC-link capacitors to fully discharge (refer to Table 1.1 Discharge Time) before servicing. Use proper electrostatic discharge (ESD) procedures and never touch electrical parts when connected to mains. Only qualified personnel should perform service.

How can I verify the presence of input signals on the TR170 VFD's control terminals?
The presence of signals on digital or analog input terminals can be verified on the VFD display by selecting digital or analog input status in parameters 16-60 to 16-64. Alternatively, use a voltmeter to measure voltage at the control terminals directly.

Why is electromagnetic compatibility (EMC) important for the Trane TR170 VFD installation?
EMC is crucial to prevent electromagnetic interference (EMI) from causing motor speed fluctuations, serial communication errors, CPU faults, or unexplained trips. Proper grounding, cable routing, and shielded cables minimize EMI effects on both the VFD and other connected equipment.

What tests should be performed after repairing or initially starting up a Trane TR170 VFD?
After repair or initial start-up, perform visual inspection, static tests for short circuits, disconnect motor cables and test output voltage balance (within 8 V AC), then reconnect motor and test output current balance (within 2-3% phase-to-phase) at nominal speed and load.
