Section 1. Regenerative Drives
Most non-regenerave,
variable speed, DC drives
control current ow to a
motor in one direcon.
The direcon of current
ow is the same direcon
as the motor rotaon.
Non-regenerave drives
operate in Quadrant I,
and also in Quadrant III if
the drive is reversible (see
Figure 1). Motors must stop
before reversing direcon.
Unless dynamic braking
is used, non regenerave
drives cannot decelerate a
load faster than coasng to a
lower speed.
Regenerative drives operate
in two addional quadrants:
Quadrant II and Quadrant
IV. In these quadrants,
motor torque is in the
opposite direcon of motor rotaon.
This allows regenerave drives to reverse a motor without contractors
or switches, to control an overhauling load, and to decelerate a load
faster than it would to coast to a lower speed.

Mounng
• Drive components are sensitive to electrostatic 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 terminals and calibration
trim pots.
• Mount the drive away from heat sources. Operate the drive within
the specified ambient operating temperature range.
• Prevent loose connections by avoiding excessive vibration of the
drive.
• Mount the drive with its board in either a horizontal or vertical plane.
Six 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 mounting screws to penetrate the
anodized surface and to reach bare metal.

Shielding Guidelines
Under no circumstances should power and logic level leads be
!
As a general rule, Minarik Drives recommends shielding of all conductors.
If it is not praccal to shield power conductors, it is recommended
to shield all logic-level leads. If shielding of all logic-level leads is not
praccal, 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 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 connues to pick up noise aer grounding the shield, it may
be necessary to add AC line ltering devices, or to mount the drive in a
less noisy environment.
Logic wires from other input devices, such as moon controllers and PLL
velocity controllers, must be separated from power lines in the same
manner as the logic I/O on this drive.

Power Input
Connect the AC line power leads to terminals L1 and L2. Minarik Drives
recommends the use of a single-throw, double-pole master power
switch. The switch should be rated at a minimum of 250 volts and 200%
of motor current. Refer to Figure 6 on page 15.
Motor
Drives supply motor armature voltage from A1 and A2 terminals. It is
assumed throughout this manual that, when A1 is posive with respect
to A2, the motor will rotate clockwise (CW) while looking at the output
sha protruding from the front of the motor. If the motor does not
spin in the desired direcon, remove power and reverse the A1 and A2
connecons.
Connect a DC motor to terminals A1 and A2. Refer to Figure 6 on page

Speed Adjust Potenometer
Use a 10K ohm, 1/4 W potenometer for speed control. The motor can
operate in one direcon (unidireconal) or two direcons (bidireconal)
depending on how the speed adjust potenometer is connected to the
drive.
For unidireconal operaon in the foward direcon, connect the speed
adjust potenometer as shown in Figure 7(a).
For unidireconal operaon in the reverse direcon, connect the speed
adjust potenometer as shown in Figure 7(b).
For bidireconal operaon, connect the speed adjust potenometer
as shown in Figure 7(c). The motor does not operate when the
potenometer is in the center posion. Turning the potenometer
clockwise (CW) from the center posion causes the motor to rotate in
the forward direcon, while turning the potenometer counterclockwise
(CCW) causes rotaon in the reverse direcon.

Analog Input Signal (non -PCM models)
Instead of using a speed adjust potenometer, the drive may be wired to
follow an analog input voltage signal that is isolated from earth ground
(Figure 8). Connect the signal common (–) S0. Connect the signal input
(+) to S2. A potenometer can be used to scale the analog input voltage.
An interface device, such as Minarik Drives model PCM4, may be used to
scale and isolate an analog input voltage.
An analog input voltage range of -10 to 10 VDC is required to produce
an armature voltage range of -90 to 90 VDC with 115 VAC line voltage or
-180 to 180 VDC with 230 VAC line voltage.

Startup
1. Turn the speed adjust potentiometer or input voltage signal to
minimum speed.
2. Apply AC line voltage.
3. 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. Continue until the desired speed is
reached.
4. Remove AC line voltage from the drive to coast the motor to a
stop.

Starng and Stopping Methods
Regenerave braking, coasng to a stop, or decelerang to
minimum speed is recommended for frequent starts and stops.
!
Automac Restart Upon Power Restoraon
All drives automacally run to set speed when power is applied and the
Regen Brake and Inhibit are open.
Line Starng and Stopping
Line starng and stopping (applying and removing AC line voltage) is
recommended for infrequent starng and stopping of a drive only. When
AC line voltage is applied to the drive, the motor accelerates to the speed
set by the speed adjust potenometer or analog signal. When AC line
voltage is removed, the motor coasts to a stop.
Do not use any of these methods for emergency stopping. They
WARNING!
may not stop a drive that is malfunconing. Removing AC line
power (both lines) is the only acceptable method for emergency
stopping.
For this reason, Minarik Drives strongly recommends installing
an emergency stop switch on both AC line inputs (see Figure 6
on page 15).
Frequent starng and stopping can produce high torque. This
may cause damage to motors, especially gearmotors that are not
properly sized for the applicaon.

Page 31
Inhibit - Regenerave Brake to Zero Speed
Short the inhibit terminals to regeneravely brake the motor to zero
speed (see Figure 12). The inhibit bypasses the deceleraon rate set by
the ACC-DEC trim pot. Open the inhibit terminals to accelerate the motor
to set speed.
Twist inhibit wires and separate 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.
SO502 terminals are installed for future interfaces. Leave the factory
installed jumper (INH and -24 terminals) in place.

Maximum Speed (MAX SPEED)
The MAX SPD seng determines the maximum motor speed when the
speed adjust potenometer or input voltage signal is set for maximum
speed.
To calibrate MAX SPD:
1. Set the MAX SPD trim pot full CCW.
2. Set the speed adjust potentiometer or input voltage signal for
maximum speed.
3. Adjust MAX SPD until the desired maximum speed is reached.
If using a -PCM model, set the MAX SPD trim pot fully CW.
Acceleraon-Deceleraon (ACC-DEC)
The ACC-DEC trim pot seng determines the me the motor takes to
accelerate to a higher speed or decelerate to a lower speed within the
limits of available torque. ACC-DEC is set for its fastest acceleraon and
deceleraon me (full CCW).
Turn the ACC-DEC trim pot CW to increase the acceleraon and

IR Compensaon (IR COMP)
The IR COMP seng determines the degree to which motor speed is held
constant as the motor load changes.
Use the following procedure to recalibrate the IR COMP seng:
1. Set the IR COMP trim pot to minimum (full CCW).
2. Increase the speed adjust potentiometer or input voltage signal
until the motor runs at midspeed without load (for example,
900 RPM for an 1800 RPM motor). A handheld 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 trim
pot until the motor runs at the speed measured in step 2. If
the motor oscillates (overcompensation), the IR COMP trim pot
may be set too high (CW). Turn the IR COMP trim pot CCW to
stabilize the motor.
5. Unload the motor.
