RG60U-T / RG61U-T SPEED/TORQUE CARD SWITCH SETTINGS RG60U Series with Speed / Torque Adder Card Q U I C K S T A R T • SPEED/TORQUE SWITCH connect contacts to the two “ST” terminals on TB501. • 10 KOHM SPEED/TORQUE POTENTIOMETER connect contacts to S1, S2, and S3 on TB501. G U I D E The SPEED/TORQUE option card gives added capability to the RG60U Series allowing control of torque or speed in either the forward or reverse directions. Selection of torque or speed mode requires a dry contact relay or switch closure. Torque control of a regen drive allows the user to control overhauling loads and the ability to perform basic open loop web tensioning and wind-up applications. • DIRECTION SWITCH connect a single pole, two position switch to R1, R2, & R3 on TB501 as shown.

Dangerous voltages exist on the drive when it is powered. When possible, disconnect the voltage input from the drive before adjusting the trimpots. If the trimpots must be adjusted with power applied, use insulated tools and the appropriate personal protection equipment. BE ALERT. High voltages can cause serious or fatal injury. Model Armature Current Range (ADC) Armature Horsepower RG60U-T MAXIMUM SPEED (MAX SPD) The MAX SPD trimpot setting determines the maximum forward and reverse speed. It is factory set for maximum rated motor speed. To 1. 2. 3. calibrate MAX SPD: Set the MAX SPD trimpot to full CCW. Turn the speed adjust potentiometer CW so that the motor is running at full speed. Adjust the MAX SPD trimpot until the desired maximum motor speed is reached. CAUTION! Do not attempt to run the motor above 90 VDC on 115 VAC, or above 180 VDC on 230 VAC. FORWARD TORQUE (FWD TQ) WARNING! Although FWD TQ can be set to 120% of motor nameplate current rating, continuous operation beyond this rating may damage the motor. If you intend to operate beyond this rating, contact your Minarik representative for assistance. The FWD TQ setting determines the maximum current limit for accelerating and driving the motor in the forward direction. It is factory set at 120% of maximum rated drive current. To 1. 2. 3. 4. 5. 6. calibrate FWD TQ: With the power disconnected from the drive, connect a DC ammeter in series with the armature. Set the FWD TQ trimpot to minimum (full CCW). Set the speed adjust potentiometer to maximum (full CW). Carefully lock the motor armature. Be sure that the motor is firmly mounted. Apply line power. The motor should be stopped. Slowly adjust the FWD TQ trimpot CW slowly until the armature current is 120% of motor rated armature current. 7. Set the speed adjust potentiometer to minimum. 8. Remove the power from the drive. 9. Unlock the motor shaft. 10. Remove the ammeter in series with the motor armature if it is no longer needed and re-apply power to the drive. REVERSE TORQUE (REV TQ) WARNING! Although REV TQ can be set to 120% of motor nameplate current rating, continuous operation beyond this rating may damage the motor. If you intend to operate beyond this rating, contact your Minarik representative for assistance. The REV TQ setting determines the maximum current limit for accelerating and driving the motor in the reverse direction. It is factory set at 120% of maximum rated current. To 1. 2. 3. 4. 5. 6. calibrate REV TQ: With the power disconnected from the drive, connect a DC ammeter in series with the armature. Set the REV TQ trimpot to minimum (full CCW). Set the speed adjust potentiometer to maximum (full CW). Carefully lock the motor armature. Be sure that the motor is firmly mounted. Apply line power. The motor should be stopped. Slowly adjust the REV TQ trimpot CW slowly until the armature current is 120% of motor rated armature current. 7. Set the speed adjust potentiometer to minimum. 8. Remove the power from the drive. 9. Unlock the motor shaft. 10. Remove the ammeter in series with the motor armature if it is no longer needed and re-apply power to the drive. IR COMPENSATION / REGULATION (IR COMP) The IR COMP trimpot setting determines the degree to which motor sped is held constant as the motor load changes. It is factory set for optimum motor regulation. The IR COMP only needs to be calibrated in speed mode. To calibrate IR COMP: 1. Set the IR COMP trimpot to minimum (full CCW). 2. Rotate the speed adjust potentiometer until the motor runs at mid-speed without load (for example, 900 RPM for an 1800 RPM motor). A handheld tachometer may be used to measure motor speed. 3. Load the motor armature to its full load armature current rating. The motor should slow down. 4. While keeping the load on the motor, rotate the IR COMP trimpot until the motor runs at the speed measured in step 2. If the motor oscillates (overcompensation), the IR COMP trimpot may be set too high (CW). Turn the IR COMP trimpot CCW to stabilize the motor. 5.0* 1/4 - 1/2* 0 - 90 5.0** 1/4 – 1** 0 – 180 1.5 1/20 - 1/8 0 - 90 1.5 1/10 - 1/4 0 - 180 RG61U-T * Max. Armature Current = 10 ADC and Max. Horsepower = 1 hp when mounted to heat sink kit part number 223-0159. ** Max. Armature Current = 10 ADC and Max. Horsepower = 2 hp when mounted to heat sink kit part number 223-0159. AC Line Voltage Form Factor FORWARD ACCELERATION (FWD ACC) The FWD ACC setting determines the time the motor takes to ramp to either a higher speed in the forward direction or a lower speed in the reverse direction, within the limits of available torque. The FWD ACC setting is factory set for its fastest forward acceleration time. Turn the FWD ACC trimpot CW to increase the forward acceleration time, and CCW to decrease the forward acceleration time. 115 VAC / 230 VAC, ±10%, 50/60 Hz, single phase 1.37 at base speed Acceleration Time Range 0.5 – 6 seconds Deceleration Time Range 0.5 – 6 seconds Analog Input Voltage Range (signal must be isolated; COM to S2) REVERSE ACCELERATION (REV ACC) The REV ACC setting determines the time the motor takes to ramp to either a higher speed in the reverse direction or a lower speed in the forward direction, within the limits of available torque. The REV ACC setting is factory set for its fastest reverse acceleration time. Turn the REV ACC trimpot CW to increase the reverse acceleration time, and CCW to decrease the reverse acceleration time. Voltage Range (VDC) 0 – 10 VDC Load Regulation with Armature Feedback with Tachogenerator Feedback Vibration 1% base speed 0.1% base speed 0.5G max. (20–50 Hz) 0.1G max. (> 50 Hz) DEADBAND (DB) The deadband trimmer potentiometer determines the time that will elapse between the application of current in one direction before current is applied in the opposite direction. Ambient Temperature Range 10°C – 55°C Weight 1.1 lb The deadband trimmer potentiometer affects the resistance that a motor has to changes in shaft position at zero speed. It does this by applying AC voltage to the motor armature. Deadband is factory calibrated with the notch at approximately the 3 o’clock position for 60 Hz AC line operation. Recalibrate the deadband with the notch at the 9 o’clock position for 50 Hz AC line operation. If you hear motor noise (humming), the deadband might be set too high. Turn the deadband trimpot CCW until the motor noise ceases. TACH GENERATOR (TACH) Calibrate the TAC setting only when a tachogenerator is used. The TACH setting, like the IR COMP setting, determines the degree to which motor speed is held constant as the motor load changes. To calibrate TACH: 1. Connect the tachogenerator to T1 and T2. The polarity is positive (+) and negative (-) for T2 with the motor running in forward direction. 2. Set SW503 to ARM for armature feedback. 3. Set the speed adjust potentiometer full CW. Measure the armature voltage across A1 and A2 using a voltmeter. 4. Set the speed adjust potentiometer to 0 (zero speed). 5. Set SW503 to TACH for tachgenerator feedback. 6. Set the IR COMP trimpot to full CCW. 7. Set the TACH trimpot to full CW. 8. Apply line power. 9. Set the speed adjust potentiometer to full CW. 10. Adjust the TACH trimpot until the armature voltage is the same value as the voltage measured in step 3. Check that the tachogenerator is properly calibrated. The motor should run at the same speed when SW503 is set to either armature or tachogenerator feedback.7 M I N A R I K D R I V E S w w w . m i n a r i k d r i v e s . c o m 14300 De La Tour Drive, South Beloit, IL 61080; Phone: (800) MINARIK (646-2745); Fax: (815) 624-6960 Document Number: 250-0374, Revision 2; Printed in the U.S.A. - May 2005 Copyright 2005 by Minarik Corporation - All rights reserved.
