Rugged, compact, low cost precision control of speed or ratio with full PID.
Uni-Track 1 Digital Speed Controller
The Uni-Track 1 is a 5-decade, high resolution digital speed controller which can be set up to control the precise speed of one motor (master mode), or to force one motor driven process to follow another at a matched or proportional speed. The Uni-Track 1 is front panel programmable accepting single channel encoder, zero speed pickup, magnetic pickup, AC tach, and even a DC tach as a master reference or feedback. This controller with its isolated 0 to 10 VDC speed reference output can directly interface with virtually every type of AC/DC variable speed drive. The polarity of the isolated reference output can be inverted through the direction input of the controller permitting bidirectional motor speed or ratio control. The bidirection control, with the inverse ratio programmability, makes this device an excellent choice for traversing winder type applications. All control inputs of the Uni-Track 1 are optically isolated for increased noise immunity and ease of interface to PLC's and other process controllers.

The Uni-Track 1 is fully programmable on the fly through the front panel keypad or through the optional serial port in any engineering unit with a self-calibrated display. One or all of the set-up parameters or the set point can be altered without interrupting production. There are many standard features incorporated into the Uni-Track 1 to control and stabilize the most adverse machine control applications. In the follower mode, situations where the follower motor is stopped and restarted with the master operating at line speed, the Uni-Track 1 can start the follower motor and reach the programmed ratio speed smoothly.
Applications: In Master Mode - Precise Speed Control of Metering Pumps, Extruders, Mixing Pumps, Baking and Heat Treating Conveyors, etc. In Follower Mode - Traverse Controller for Wire & Cable Winders, Packaging Machinery, etc.

A variety of software options and custom modifications available.
Example-Dual Preset, Dancer Input, etc.

Sensor Power - + 12 VDC regulated at 100 mA
Control Inputs - 3 optically isolated control inputs
   Run/Stop, Direction, Hold with Jog
        <OR>
   Run/Stop, Increase, Decrease with Jog
Sensor Input - Selectable to accept input pulses from square wave encoders, zero speed pickup, magnetic pickup, or an AC tach.
- 1 Hz to 50 kHz in master or follower mode.
Analog Input - 0 to +10 VDC input to the voltage controlled oscillator. This will convert to 1 Hz to 1000 Hz maximum frequency output which can be used as one of the sensor inputs to convert an analog tach to digital, or to set speed by a pot.
Discrete Outputs - 2 open collector outputs capable of sinking current with up to 50 mA at 24 VDC.
- Zero speed will be on when zero feedback is sensed.
- 1 to 1000 Hz output proportional to analog input.
Analog Output - Isolated drive reference 0 to 10 VDC. Polarity is selected via direction input. 5 mA max. 12 bit resolution.
Data Storage Type - Non-volatile EEPROM. All parameters are retained when power is removed.
Response Time - 10 milliseconds control loop update for PID and feedforward. (1 millisecond optional.)
Setpoints - Speed/ratio, jog speed. 5-decade with programmable decimal points in user defined units.
Standard Control Options
- Master mode:
regulate the speed of one motor precisely to match the set speed.
- Follower mode: regulate the speed of one motor precisely to follow the lead motor by the set ratio.
- Inverse ratio: regulate the speed of the follower motor to match 1/ratio.
- Optional: dancer (loop sensor) input.
Accel/Decel - Separately programmable 0.00 to 600 seconds with user programmable decimal point. Tuning
- (PID) separately programmable gain, integral, rate.
- Feedforward and open loop response.
- Error limit and correction factor.
Operator Interface
- 7 digits 0.6" high, bright red modified alpha-numeric LED display for programming and speed, ratio, and error read out, calibrated in engineering units.
- 6 key, simple menu-driven set-up and tuning.
Optional Serial Interface - RS422/RS485/RS232, programmable baud rate 300 to 4800. (Others Avail.)
Operating Temperature - 0 to 55 C (32 to 131 F)
