Installation

Mounting

•

Drive components are sensitive to electrostatic fields. Avoid direct contact with the circuit board.

• Protect the drive from dirt, moisture, and accidental contact.

• Mount the drive away from other heat sources. Operate the

drive within the specified ambient operating temperature range.

• Prevent loose connections by avoiding excessive vibration of

the drive.

• Mount C1XP drives vertically or horizontally using the two

mounting keyholes on the back of the case (Figure 2). The keyholes are 2.5 inches apart. For access to the keyholes from the inside of the case, remove the four case cover screws, lift the case cover straight out, and remove the fishpaper from inside the back cover. Leave the case cover removed to wire the AC line and motor to the drive. After mounting, remember

to return the fishpaper to the inside back cover, as it provides

necessary electrical isolation!

Installation

Wiring

Use 16 AWG wire for motor and AC line voltage wiring.

Shielding guidelines

As a general rule, Minarik Drives recommends shielding of all conductors if:

1) wire lengths exceed 18 inches, with separation of power and logic leads;

2) wire lengths exceed 4 inches and power and logic leads must be bundled together*;

3) radiated and/or conducted noise must be minimized due to concerns about immunity or general compliance (CE, FCC, etc.)

*Minarik Drives considers this an unfavorable condition and does not recommend bundling of power and logic leads for any length.

If it is not practical to shield power conductors, Minarik Drives recommends shielding all logic-level leads. If shielding is not practical, the user should twist all logic leads with themselves to minimize induced noise.

Under no circumstances should power and logic leads

be bundled together. Induced voltage can cause unpredicatable

behavior any electronic device, including motor controls.

It may be necessary to earth ground the shielded cable. If noise is produced by devices other than the drive, ground the shield at the drive end. If noise is generated by a device on the drive, ground the shield at the end away from the drive. Do not ground both

ends of the shield.

If the drive continues to pick up noise after grounding the shield, it may be necessary to add AC line filtering devices, or to mount the drive in a less noisy environment.

Installation

Heat sinking

All C1XP series drives have sufficient heat sinking in their basic

configurations. No additional heat sinking is required.

Line fusing

C1XP series drives come with two preinstalled fuses. Use fast acting AC line fuses rated for 250 volts, and approximately 150% to 200% of the maximum armature current.

Installation

Warning

This product does not have internal solid state motor overload protection.

It does not contain speed-sensitive overload protection, thermal memory retention or provisions to receive and act upon signals

from remote devices for over temperature protection.

If motor overload protection is needed in the end-use product, it needs to be provided by additional equipment in accordance

with NEC standards.

Connections

Installation

ASSUMPTIONS:

Minarik Drives’s drives supply motor voltage to terminals A1 and A2 (A1 is positive with respect to A2). It is assumed throughout this manual that the driven motor will rotate clockwise (CW) while looking at the output shaft protruding from the front of the motor. If the opposite is desired, simply reverse the wiring of A1 and A2 with each other.

MOTOR ARMATURE

Figure 2. C1XP Connections

Operation

Before applying power

• Verify that no conductive material is present on the printed

circuit board.

• Verify that the AC supply is properly balanced.

Startup

To start the drive:

1. Turn the speed adjust potentiometer knob CW to turn the power on (an audible “click” will be heard). The POWER ON LED lights when the power is on.

2. Rotate the speed adjust potentiometer knob clockwise until the

desired speed is reached.

3. Turn the speed adjust potentiometer knob full CCW to turn the power off (an audible “click” will be heard). The POWER ON LED is extinguished when the power is off.

Operation

Line starting and line stopping

When AC line voltage is applied to the drive, the motor accelerates to the set speed. When AC line voltage is removed, the motor coasts to a stop. Line starting and line stopping (applying and removing AC line voltage) is recommended for starting and stopping in emergency situations only. It is not recommended for frequent starting and stopping.

Calibration

C1XP Series drives have four user adjustable trimpots: MAX, MIN, CURR. LIMIT, and IR COMP.

Recalibrate the trimpots if a different horsepower motor is used. All trimpot settings increase with clockwise (CW) rotation, and decrease with counterclockwise (CCW) rotation. Use a nonmetallic screwdriver for calibration. Each trimpot is identified on the printed circuit board.

Calibration

MAX (MAXIMUM SPEED)

The MAX trimpot setting determines the motor speed when the speed adjust potentiometer is turned full CW. It is factory set for 90 VDC (full load voltage)..

To calibrate MAX trimpot setting:

1. Set the MAX trimpot full CCW.

2. Turn the speed adjust potentiometer full CW.

3. Adjust the MAX SPD trimpot until the desired maximum

motor speed is reached.

MIN (MINIMUM SPEED)

The MIN trimpot setting determines the motor speed when the speed adjust potentiometer is turned full CCW. It is factory set to zero speed.

To calibrate MIN trimpot setting:

1. Turn the speed adjust potentiometer full CCW.

2. Adjust the MIN trimpot until the motor has stopped, or is

running at the desired minimum speed.

Note: Check the MIN and MAX trimpot setting after recalibrating to verify that the motor runs at the desired minimum and maximum speed.

Calibration

CURR. LIMIT

The CURR. LIMIT trimpot setting determines the maximum armature current output of the drive. It is factory calibrated to 1 ADC for C1XP01 drives, and 3 ADC for C1XP03 drives.

To calibrate CURR. LIMIT:

1. With the power disconnected from the drive, connect a DC

ammeter in series with the armature.

2. Set the CURR. LIMIT trimpot to minimum (full CCW).

3. Connect power to the drive. Push the speed adjust

potentiometer knob to turn the power on. The motor should remain stopped.

4. Lock the motor shaft. Be sure that the motor is

firmly mounted.

5. Set the speed adjust potentiometer to maximum (full CW).

6. Adjust the CURR. LIMIT trimpot CW slowly until the

armature current is 120% of motor rated armature current.

7. Set the speed adjust potentiometer to minimum and remove

the stall from the motor.

Warning!

Although the CURRENT LIMIT trimpot can be set to exceed the motor’s maximum armature current rating, we recommend you do not run the motor continuously beyond that rating. Continuous operation beyond the maximum armature current rating may cause thermal degradation of the motor and drive.

Calibration

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.

To calibrate IR COMP (exact calibration):

1. Turn the IR COMP trimpot full CCW.

2. Set the speed adjust potentiometer until the motor runs at

midspeed without load (for example, 900 RPM for an 1800 RPM motor) A hand held 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.

Approximate calibration:

If the motor does not maintain set speed as the load changes, gradually rotate the IR COMP trimpot CW. 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 speed.
