Page 22: Figure 6 Analog Input Signal Connections (Pat443)
PAT Series Analog Input Signal (PAT443) Instead of using a speed adjust potentiometer, the drive may be wired to follow an analog input voltage or current signal that is either isolated SIG MIN. SIG MAX or non-isolated from earth ground. Connect the signal common (-) to S1. -
Page 23: Section 4. Operation
PAT Series Section 4. Operation Change voltage switch settings only when the drive is disconnected from AC line voltage. Make sure both switches are set to their correct position. If the switches are improperly set to a lower voltage position, the motor will not run at full voltage WARNING! and may cause damage to the transformer. -

Page 25: Startup
PAT Series Startup PAT440 Turn the speed adjust potentiometer to “0” (full CCW) or set the input voltage signal to minimum. Set the POWER switch to the ON position. Slowly advance the speed adjust potentiometer clockwise (CW) or increase the input voltage signal. The motor slowly accelerates as the potentiometer is turned CW or as the input voltage signal is increased. -
Page 26: Pat450
PAT Series PAT450 Do not change direction while the motor is running. The motor must come to a complete stop before reversing. Changing motor direction before allowing the motor to completely stop will cause WARNING! excessively high current to flow in the armature circuit, and will damage the drive and/or motor. -
Page 27: Starting And Stopping Methods
PAT Series Starting and Stopping Methods Dynamic braking, coasting to a stop, or decelerating to minimum speed is recommended for frequent starts and stops. Do not use any of these methods for emergency stopping. They may not stop WARNING! a drive that is malfunctioning. -
Page 28: Dynamic Braking
PAT Series Dynamic Braking Wait for the motor to completely stop before switching back to RUN. This will prevent high armature currents from damaging the motor or drive. WARNING! Dynamic braking may be used to rapidly stop a motor (Figure 8 on page 22). -
Page 29: Table 4 Minimum Recommended Dynamic Brake Resistor Values
PAT Series Table 4. Minimum Recommended Dynamic Brake Resistor Values Motor Armature Voltage Dynamic Brake Resistor Value 90 VDC 15 ohms 180 VDC 30 ohms For motors rated 1/17 horsepower and lower, a brake resistor is not necessary since the armature resistance is high enough to stop the motor without demagnetization. -
Page 30: Inhibit Terminals
18 inches (46 cm). If shielded cable is used, ground only one end of the shield to earth ground. Do not ground both ends of the shield. American Control Electronics offers two accessory plug harnesses for connecting to the INHIBIT terminals: part number 201-0024 [plug with 18 in. -
Page 31: Decelerating To Minimum Speed
PAT Series Decelerating to Minimum Speed The switch shown in Figure 10 may be used to decelerate a motor to a minimum speed. Closing the switch between S1 and S2 decelerates the motor from set speed to a minimum speed determined by the MIN SPD trim pot setting. -
Page 32: Section 5. Calibration
BE ALERT. High voltages can cause serious or fatal injury. PAT series drives have user-adjustable trim pots. Each drive is factory calibrated to its maximum current rating. Readjust the calibration trim pot settings to accommodate lower current rated motors. -
Page 33: Minimum Speed (Min Spd)
PAT Series Minimum Speed (MIN SPD) The MIN SPD setting determines the minimum motor speed when the speed adjust potentiometer or input voltage signal is set for minimum speed. It is factory set for zero speed. To calibrate the MIN SPD: Set the MIN SPD trim pot full CCW. -
Page 34: Torque (Tq Limit)
Continuous operation beyond this rating may damage the motor. If you intend to operate beyond the rating, contact your WARNING! American Control Electronics representative for assistance. The TQ LIMIT setting determines the maximum torque for accelerating and driving the motor. To calibrate TORQUE, refer to the recommended... -
Page 35: Ir Compensation (Ir Comp)
PAT Series IR Compensation (IR COMP) The IR COMP setting determines the degree to which motor speed is held constant as the motor load changes. Use the following procedure to recalibrate the IR COMP setting: Set the IR COMP trim pot to minimum (full CCW). -

Page 37: Acceleration (Accel)
PAT Series Acceleration (ACCEL) The ACCEL setting determines the time the motor takes to ramp to a higher speed. See Specifications on page 1 for approximate acceleration times. ACCEL is factory set for the shortest acceleration time (full CCW). To set the acceleration time: Set the speed adjust potentiometer or input voltage signal for minimum speed. -
Page 38: Section 6.Application Notes
PAT Series Section 6.Application Notes Multiple Fixed Speeds Replace the speed adjust potentiometer with a series of resistors with a total series resistance of 10K ohms (Figure 12). Add a single pole, multi- position switch with the correct number of positions for the desired number of fixed speeds. -
Page 39: Adjustable Speeds Using Potentiometers In Series
PAT Series Adjustable Speeds Using Potentiometers In Series Replace the speed adjust potentiometer with a series of resistors with a total series resistance of 10K ohms (Figure 13). Add a single pole, multi- position switch with the correct number of positions for the desired number of fixed speeds. -
Page 40: Independent Adjustable Speeds
PAT Series Independent Adjustable Speeds Replace the speed adjust potentiometer with a single pole, multi- position switch, and two or more potentiometers in parallel, with a total parallel resistance of 10K ohms. Figure 14 shows the connection of two independent speed adjust potentiometers that can be mounted at two separate operating stations. -
Page 41: Run/Jog Switch - Inhibit Connection
PAT Series RUN/JOG Switch - Inhibit Connection Using a RUN/JOG switch is recommended in applications where quick stopping is not needed and frequent jogging is required. Use a single pole, two position switch for the RUN/JOG switch, and a single pole, normally closed, momentary operated pushbutton for the JOG pushbutton. -
Page 42: Run/Jog Switch - Potentiometer Connection
PAT Series RUN/JOG Switch - Potentiometer Connection Connect the RUN/JOG switch and the JOG pushbutton as shown in Figure 16. When the RUN/JOG switch is set to JOG, the motor decelerates to minimum speed (minimum speed is determined by the MIN SPD trim pot setting). -
Page 43: Leader-Follower Application
PAT Series Leader-Follower Application In this application, use a PCM4 to monitor the speed of the leader motor (Figure 17). The ISO202-1 isolates the leader motor from the follower drive, and outputs a voltage proportional to the leader motor armature voltage. -
Page 44: Single Speed Potentiometer Control Of Multiple Drives
PAT Series Single Speed Potentiometer Control Of Multiple Drives Multiple drives can be controlled with a single speed adjust potentiometer using a ISO101-8 at the input of each drive to provide isolation (Figure 18). Optional ratio potentiometers can be used to scale the ISO101-8 output voltage, allowing independent control of each drive. -
Page 45: Reversing
PAT Series Reversing A dynamic brake may be used when reversing the motor direction (Figure 19). Use a three pole, three position switch rated for at least the maximum DC armature voltage and maximum braking current. Wait for the motor to stop completely before switching it to either the forward or reverse direction. -
Page 46: Section 7. Diagnostic Leds
PAT Series Section 7. Diagnostic LEDs PAT series drives are equipped with two diagnostic LEDs: • Power (POWER): Green LED lights whenever AC line voltage is applied to the drive. • Current Limit (TQ LIMIT): Red LED lights whenever the drive reaches current limit. -
Page 47: Section 8. Troubleshooting
PAT Series Section 8. Troubleshooting Dangerous voltages exist on the drive when it is powered. When possible, disconnect the drive while troubleshooting.
