Safety Warnings
•
Have a qualified electrical maintenance technician install,
adjust, and service this equipment. Follow the National
Electrical Code and all other applicable electrical and safety
codes, including the provisions of the Occupational Safety
and Health Act (OSHA) when installing equipment.
•
Reduce the chance of an electrical fire, shock, or explosion by
proper grounding, over current protection, thermal protection,
and enclosure. Follow sound maintenance procedures.
•
It is possible for a drive to run at full speed as a result of a
component failure. Install a master switch in the AC line for
stopping the drive in an emergency.
•
This drive is not isolated from earth ground. Circuit potentials
are at 115 VAC or 230 VAC above earth ground. Avoid direct
contact with the printed circuit board or with circuit elements
to prevent the risk of serious injury or fatality. Use a nonmetallic screwdriver for adjusting the calibration trimpots.

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
5
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.
6
Installation
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.
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.

Installation
Connections
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.

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.
10
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.
11
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.

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.
13
14
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.
