This unit is perfect for the OEM looking to control speed of a single phase AC motor such as ones used in fans and exhaust systems. Permanent split capacitor (PSC), synchronous, and shaded pole motors can be used with this drive. TA10-D drives are capable of maintaining a set speed even as the AC input line voltage sags or swells. Other options include thermistor feedback for temperature control or a set point voltage for a PI closed loop feedback. STEP ONE: SET JUMPERS S T E P T H R E E : C A L I B R AT I O N There are three modes of operation for the TA10-D drive. Select the one mode that best fits your application. Mode 1: Voltage Control. Jumper VOLT CONT. on J502 for open loop operation using either the speed potentiometer or external 0-5 VDC signal for speed adjustment. Voltage Control is the most commonly used mode of operation. Mode 2: Thermistor Feedback. Jumper TH FBK on J502 for closed loop control with customer supplied thermistor feedback. Thermistor Feedback is used to maintain a temperature. Mode 3: Voltage Feedback (PI). Jumper FBK on J502 for closed loop control using an isolated 0-15 VDC feedback signal. The PI is not field adjustable. MIN SPD Minimum speed sets the output speed when the speed pot is turned fully counterclockwise. Adjusting MIN SPD clockwise will increase the minimum speed. MIN SPD is factory calibrated for 0 speed. MAX SPD Maximum speed sets the output speed when the speed pot is turned fully clockwise. Adjusting the MAX SPD clockwise will increase the maximum speed. MAX SPD is factory calibrated for maximum rated output voltage. FDBK SCALE Feedback scale is only used if J502 is set to FBK or TH FBK, and a feedback device is connected to TB502 or TB503. Note: J501 is for factory programming only. DO NOT connect anything to J501. STEP TWO: WIRE DRIVE A Connect speed potentiometer to S1, S2, and S3 on TB501. An isolated 0-5 VDC signal connected to S1 (com) and S2 (input) can be used in place of a speed pot. B An optional start/stop switch can be wired between INH and COM on TB501. Close to stop. C Connect optional feedback signal to TB502 or TB503 as described in Calibration section. Do not connect a feedback signal to TB502 or TB503 if J502 is set to VOLT CONT. D Connect motor to M1 and M2. Polarity does not matter. E Connect AC voltage supply to L1 and L2.

Set speed pot or analog signal to a test temperature. Allow time for actual temperature to stabilize. Adjust FDBK SCALE pot in small increments over time until actual temperature equals test temperature setting. This calibration can be done at the Minarik Drives factory for OEMs. VOLTAGE FEEDBACK (PI) Connect analog voltage feedback signal to FDBK and COM on TB502. Set process control signal (speed pot or voltage signal to S1 and S2) to a test point. Adjust FDBK SCALE pot until the process operates at the test point. This calibration can be done at the Minarik Drives factory for OEMs. Copyright 2006 by Minarik Drives - All rights reserved.
