THE TCF SERIES - Sensorless Vector AC drive

Delivering torque when you want it, where you want it - the TCF Series from AC Tech will control your motor down to 1Hz at full output torque! When you really need torque, for impact loading or acceleration, the TCF can provide up to 200% motor rated torque.

The TCF is designed for easy integration into your control panel. The compact, contactor style drive conserves panel space and simplifies wiring. Start-up is simplified as well with auto tuning to make sure you get all of the performance you need in either Vector or V/Hz mode.

General Specifications
Horsepower: 0.5 to 10 HP (0.37 to 7.5 kW)

Supply Power:
Single Phase:   208, 220 or 240VAC
Three Phase:   208, 240, 400, 480 or 590VAC
                          50 / 60 Hz

Motors: The TCF is designed for operation vector duty rated induction motors rated for 200, 230, 400, 460 or 575VAC from 0 to 240Hz.

Enclosure: IP20 with finger safe terminals

Standard Features
Easy Set-up and Operation:   Program the TCF one of four convenient ways:

  • From the front of the drive
  • The optional remote keypad 
  • A PCUsing AC Tech's TechLink Software (TechLink is free in the Technical Library)
  • The innovative EPM Programmer.

Modes of operation:

  • Constant Torque V/Hz
  • Variable Torque V/Hz
  • Sensorless Vector - speed mode
  • Sensorless Vector - torque mode

Auto Tuning: Determines key performance values based on the motor and installation variables. Required for vector modes but can be used to enhance performance in V/Hz mode.

Motor Thermal Overload: Approved as a motor protection device for single motor applications by UL and cUL.

Control I/O: 18 isolated terminals provide 5 logic inputs and 2 logic outputs. Two reference inputs allow for 4-20 mA and -10 to +10 VDC. Two analog outputs indicate speed and load. 2 wire RS485 for Modbus RTU serial communication connection.

TCF Options

Remote Keypad: Simple four wire connection to the TCF for operation and programming of the drive. High-impact plastic and gasket permit installation in NEMA 4X (IP65) environments.

Dynamic Braking Kit:
Prepackaged resistor modules with control electronics provide solution for applications requiring braking on deceleration or stopping.
(instruction sheet available in Library)

DIN Rail Mounting Kit:
Allows easy mounting of the TCF drive or dynamic braking kits onto standard DIN Rail.
(instruction sheet available in Library)

AC Line Filters:
AC input line filters are available for all sub-micro drives to meet European requirements for susceptibility and emissions of electrical and radiated noise (EN 61800-3 and EN 5501). The filter is designed to mount to the electrical panel and has provisions for mounting the drive directly to the face of the filter.

EPM Programmer:
Copy drive programs in 2 seconds using the EPM Programmer! Then just plug the EPM into the TCF Series drive and it's ready for operation. The EPM Programmer also provides full programming capability using the backlit LCD display. Archiving of programs to a PC only requires an RS232 cable and free TechLink Software.
