• 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.

WARNING!
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.

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.

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.

reverse direction. It is factory set at 120% of maximum rated current.

armature current.

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.

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.

time. Turn the REV ACC trimpot CW to increase the reverse acceleration time, and CCW

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
