Safety Warnings
•
DO NOT INSTALL, REMOVE, OR REWIRE THIS EQUIPMENT WITH POWER APPLIED.
Have a
•
qualified electrical technician install, adjust and service this equipment. Follow the Na�onal
•
Electrical Code and all other applicable electrical and safety codes, including the provisions of the
•
Occupa�onal Safety and Health Act (OSHA), when installing equipment.
•
Circuit poten�als are at 115 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 non-
•
metallic screwdriver for adjus�ng the calibra�on trim pots. Use approved personal protec�on
•
equipment and insulated tools if working on this drive with power applied.
• Reduce the chance of an electrical fire, shock, or explosion by using proper grounding techniques,
•
over-current protec�on, thermal protec�on, and enclosure. Follow sound maintenance procedures.
•
Midwest Mo�on Products strongly recommends the installa�on of a master power switch in the
•
line voltage input.
The switch contacts should be rated for 250 VAC and 200% of motor nameplate
•
current.
•
Do not disconnect any of the motor leads from the drive
unless power is removed or the drive is
•
disabled. Opening any one lead while the drive is running may destroy the drive.
• Under no circumstances should power and logic level wires be bundled together.
• Be sure poten�ometer tabs do no make contact with the poten�ometer’s body. Grounding the
•
input will cause damage to the drive.

Installation
Moun�ng
• Drive components are sensi�ve to electrosta�c discharge. Avoid direct contact with the circuit
•
board. Hold the drive by the chassis or heat sink only.
• Protect the drive from dirt, moisture, and accidental contact.
• Provide sufficient room for access to the terminal block and calibra�on trim pots.
• Mount the drive away from heat sources. Operate the drive within the specified ambient opera�ng
•
temperature range.
• Prevent loose connec�ons by avoiding excessive vibra�on of the drive.
• Mount the drive with its board in either a horizontal or ver�cal plane. Eight 0.19” (5 mm) wide slots
•
in the chassis accept #8 pan head screws. Fasten either the large base or the narrow flange of the
•
chassis to the subplate.
• The chassis should be earth grounded. Use a star washer beneath the head of at least one of the
•
moun�ng screws to penetrate the anodized chassis surface and to reach bare metal.
Heat Sinking
The drive requires an addi�onal heat sink when the con�nuous armature current is above 5 amps.
Use a thermally conduc�ve heat sink compound (such as Dow Corning 340® Heat Sink Compound)
between the chassis and the heat sink surface for op�mal heat transfer.
Wiring
Use 18 - 24 AWG wire for logic wiring. Use 14 - 16 AWG wire for AC line and motor wiring.
Shielding Guidelines
As a general rule, it is recommended to shield all conductors. If it is not prac�cal to shield power
conductors, it is recommended to shield all logic-level leads. If shielding of logic-level leads is not
prac�cal, the user should twist all logic leads with themselves to minimize induced noise. 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 the drive, ground the shield at the end
away from the drive. Do not ground both ends of the shield.
Fusing
The drive requires an external line fuse for protec�on. Use fast ac�ng fuses rated for 250 VAC or
higher and 150% of the maximum armature current. Fuse the HOT leg of the AC line when using 115
VAC and both lines when using 230 VAC.

Line Input
Connect the AC line power leads to terminals L1 and L2.
MMP
recommends the use of a double-pole,
single-
throw master power switch. The switch should be rated at a minimum of 250 VAC and 200% of motor
current.
Motor
Connect the DC armature leads to terminals A1 and A2. If the motor does not spin in the desired direc�on,
power down the drive and reverse these connec�ons.
LOGIC
Speed Poten�ometer
Use a 10K ohm, 1/4 W poten�ometer for speed control. Connect the counter-clockwise end of the
poten�ometer to S1, the wiper to S2, and the clockwise end to S3. If the poten�ometer works inversely of
desired func�onality, (i.e. to increase motor speed, you must turn the poten�ometer counterclockwise),
power off the drive and swap the S1 and S3 connec�ons.
Analog Input Signal Range
The drive may be wired to follow an analog input voltage signal (0-5 VDC). Because these drives have
built in isola�on, the input signal can be grounded or ungrounded (floa�ng). Connect the signal common (-)
to S1 and the signal input (+) to S2.
Inhibit
Short the INHIBIT terminals to coast the motor to zero speed. Open the INHIBIT terminals to
accelerate the motor to set speed. Twist inhibit wires and seperate them from power-carrying wires or
sources of electrical noise. Use shielded cable if the inhibit wires are longer than 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.
Do not use the inhibit for emergency stopping
