Installation Drive mounting Warning Do not install, rewire, or remove this control with power applied. Doing so may cause fire or serious injury. Make sure you have read and understood the Safety Warnings before attempting installation. The chassis must be earth grounded. Use a star washer beneath the head of at least one of the mounting screws to penetrate the anodized chassis surface and to reach bare metal.
Installation Wiring Warning Do not install, remove, or rewire this equipment with power applied. Failure to heed this warning may result in fire, explosion, or serious injury. Circuit potentials are at 115 or 230 VAC above ground. To prevent the risk of injury or fatality, avoid direct contact with the printed circuit board or with circuit elements.
Induced voltage can cause unpredictable behavior in any electronic device, including motor controls. As a general rule, Minarik recommends shielding of all conductors. If it is not practical to shield power conductors, Minarik recommends shielding all logic-level leads. If shielding logic leads is not practical, the user should twist all logic leads with themselves to minimize induced noise.
Fusing NOTE: Model XL1100A drives do not require a line fuse on L2. All XLA Series drives are fused for maximum rated current at 115 VAC line input. A factory installed fuse is connected to L1 (hot) of the AC line input.
Installation Line Fusing for XL Series Drives Minarik Corporation offers three fuse kits: part number 050–0068 (1–8A Fuse Kit), 050–0070 (3–10A Fuse Kit), and 050–0072 (5–15A Fuse Kit). All fuse kits include a 1/2A pico fuse (part number 050–0074) which protects the transformer and logic. Refer to Replacement Parts (page 57) for fuse kit contents.
Installation Speed adjust potentiometer mounting Warning Be sure that the potentiometer tabs do not make contact with the potentiometer enclosure. Grounding the input will cause damage to the drive. Install the circular insulating disk between the mounting panel and the 10K ohm speed adjust potentiometer (see Figure 3). Mount the speed adjust potentiometer through a 0.38-inch (10 mm) hole with the hardware provided.
Installation Cage-clamp terminals XLA Series drive connections are of the cage-clamp terminal type (see Figure 4). To insert a wire into a terminal: 1. Press down on the lever arm using a small screwdriver. 2. Insert wire into the wire clamp. 3.
Figure 5 (page 19). Motor connections Minarik drives supply motor voltage from A1 and A2 terminals. It is assumed throughout this manual that, when A1 is positive with respect to A2 , the motor will rotate clockwise (CW) while looking at the output shaft protruding from the front of the motor.
(recommended). External line fuse NOTE: Model XL1100A drives do not require additional line fusing. An additional line fuse should be installed on L2 if the input voltage is 230 VAC. The line fuse should be rated at 250 volts and 150 - 200% of maximum motor nameplate current.
ADJUST POT NOTES: 1. DO NOT ADD LINE FUSE TO L2 IF USING MODEL XL1100A DRIVES. ADD LINE FUSE TO L2 FOR ALL OTHER DRIVES IF LINE VOLTAGE IS 230 VAC. 2. DO NOT CONNECT FIELD CIRCUIT IF USING A PERMANENT-MAGNET MOTOR.
Installation Field output connections Warning The field output is for shunt wound motors only. Do not make any connections to the field output when using a permanent magnet motor. Use 18 AWG wire for field connections. See Table 2 for field output connections.
S1. Make no connection to S3. A potentiometer can be used to scale the analog input voltage. To achieve greater linearity and control, use an interface device such as Minarik model PCM4 to scale the analog input voltage. Follow the same wiring guidelines used for speed adjust potentiometer wiring.
NOTE: Model XL1100A does not include these switches. Two voltage switches (SW501 and SW502) must be set to either 115 or 230 to match the AC line voltage being used. See Figure 7 for the location of the voltage switches.
Operation Warning Dangerous voltages exist on the drive when it is powered, and up to 30 seconds after power is removed and the motor stops. BE ALERT. High voltages can cause serious or fatal injury. Chane switch settings only when the drive is disconnected from AC line voltage.
Operation Startup Turn the speed adjust potentiometer full counterclockwise (CCW). If the drive is following a voltage signal, set the voltage signal to 0 VDC. Apply AC line voltage. Slowly advance the speed adjust potentiometer clockwise (CW). If a voltage signal is used, slowly increase the voltage signal.
AC line power (both L1 and L2) is the only acceptable method for EMERGENCY stopping. For this reason, Minarik strongly recommends the installation of an emergency stop switch. The switch contacts should be rated at a minimum of 250 volts and 200% of maximum motor current.
Operation Inhibit terminals Jumper the INHIBIT terminals to coast the motor to a stop (see Figure 8). Remove the jumper to accelerate the motor to set speed. Q502 Q501 D501 TH501 R503 T501 C503 R501 IC503 C501 IC502 IC501 R502 C502 POWER CURR...
Operation Inhibit plug Minarik Corporation offers two accessory plug harnesses for use with the INHIBIT terminals: Table 3. Inhibit Plug Harness Part Numbers Minarik Part Number Description 201-0024 Inhibit plug with 18 in. (46 cm) wires 201-0079 Inhibit plug with 36 in. (91 cm) wires Twist inhibit plug wires and separate them from other power- carrying wires or sources of electrical noise.
Operation Decelerate to minimum speed The circuit shown in Figure 9 may be used to decelerate a motor to a minimum speed. Closing the switch between S2 and S1 decelerates the motor from set speed to a minimum speed determined by the MIN SPD trimpot setting. If the MIN SPD trimpot is set full CCW, the motor decelerates to zero speed when the switch between S2 and S1 is closed.
Operation Dynamic braking Dynamic braking may be used to rapidly stop a motor (see Figure 10). For the RUN/BRAKE switch, use a two pole, two position switch rated to handle the motor voltage and current. For the dynamic brake resistor, use a high power, wirewound resistor (minimum 40 watts).
Operation Sizing the dynamic brake resistor Sizing the dynamic brake resistor depends on load inertia, motor voltage, and braking time. Use a lower ohm value, higher wattage, dynamic brake resistor to stop a motor more rapidly. Refer to Table 4 below for minimum recommended dynamic brake resistor sizes. Table 4.
Calibration Warning Dangerous voltages exist on the drive when it is powered, and up to 30 seconds after power is removed and the motor stops. 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.
Calibration Calibration procedure Calibrate the drive using the following procedure: Set the MIN SPD, MAX SPD, ACCEL and DECEL trimpots to zero (full CCW). Set the CURRENT LIMIT trimpot to maximum (full CW). Set the IR COMP trimpot to midrange (approximate 12 o’clock position).
Calibration MAXIMUM SPEED (MAX SPD) The MAX SPD setting determines the motor speed when the speed adjust potentiometer is turned full CW. It is factory set for maximum rated speed. To calibrate, set the MAX SPD trimpot full CCW. Set the speed adjust potentiometer or reference signal to maximum.
Calibration MAXIMUM SPEED TRIMPOT SETTING MOTOR ARMATURE USING 2.5K OHM USING 1.5K OHM VOLTAGE (VDC) SPEED ADJUST SPEED ADJUST POTENTIOMETER POTENTIOMETER APPLICABLE Figure 12. Low-Voltage DC Motor Calibration Settings...
Calibration IR COMPENSATION (IR COMP) The IR COMP trimpot setting determines the degree to which motor speed is held constant as the motor load changes. It is factory set for optimum motor regulation. Refer to Figure 13 (page 40) for typical CURR. LIMIT and IR COMP settings. To calibrate IR COMP (exact calibration): 1.
If you intend to operate beyond the rating, contact your Minarik representative for assistance. The CURRENT LIMIT setting determines the maximum torque for accelerating and driving the motor. CURRENT LIMIT is factory set at 120% of maximum drive current.
Calibration Remove power from the drive. Remove the lock from the motor shaft. 10. Remove the ammeter in series with the motor armature. 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.
Calibration DECELERATION (DECEL) The DECEL setting determines the time the motor takes to ramp to a lower speed. See Specifications on page 1 for approximate deceleration times. DECEL is factory set for the fastest deceleration time (full CCW). To set the deceleration time: Set the speed adjust potentiometer full CW.
Application Notes Multiple fixed speeds Replace the speed adjust potentiometer with series resistors with a total series resistance of 10K ohms (see Figure 14). Add a single pole, multi-position switch with the correct number of positions for the desired number of fixed speeds. TOTAL SERIES RESISTANCE 10K OHMS...
Application Notes Adjustable speeds using potentiometers in series Replace the speed adjust potentiometer with a single pole, multi- position switch, and two or more potentiometers in series, with a total series resistance of 10K ohms. Figure 15 shows the connection for two speed control with high and low speed adjust potentiometers.
Application Notes 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 16 shows the connection of two independent speed adjust potentiometers that can be mounted at two separate operating stations.
Application Notes RUN/JOG switch 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.
Application Notes RUN/JOG option #2 In the second wiring option, connect the RUN/JOG switch and the JOG pushbutton as shown in Figure 18. When the RUN/JOG switch is set to JOG, the motor decelerates to minimum speed (minimum speed is determined by the MIN SPD trimpot setting). Press the JOG pushbutton to jog the motor.
Application Notes Leader-follower application In this application, use a PCM4 to monitor the speed of the leader motor(see Figure 19). The PCM4 isolates the leader motor from the follower drive, and outputs a voltage proportional to the leader motor’s armature voltage. The follower drive uses this voltage reference to set the speed of the follower motor.
Application Notes Single speed potentiometer control of multiple drives You can control multiple drives with a single speed potentiometer using a PCM4 at the input of each drive (see Figure 20). A PCM4 is used at the input of each drive for isolation. Optional ratio potentiometers can be used to scale the PCM4 output voltage, allowing independent control of each drive.
Application Notes Reversing Always use a dynamic brake when reversing the motor direction (see Figure 21). Use a three pole, three position switch rated for the DC armature voltage and high braking current. Wait for the motor to stop completely before switching it to either the forward or reverse direction.
Figure 22 shows the reversing circuit connections with an XL Series drive and DIGI-LOK controller. Note: Only one DLC option (Optical Encoder or Magnetic Pickup) may be used at a time. MINARIK DRIVE Dynamic Brake Resistor...
