Specifications

1/4 to 60 hp
Isolated PWM AC NEMA 1,4, 12 or 4X
95
n Programmable: Can be programmed using the front keypad, remote keypad, Modbus, or through your PC using the
Techlink software available on our website www.minarikdrives.com
n Reversing: Solid-state devices make reversing as simple as closing a contact.
n Display: 16 character backlit LCD display for programming, status, and diagnostics.
n Braking: DC injection braking is standard with a dynamic braking option when faster and repetitive stops are
needed.
n Carrier frequency: Adjustable from 2.5 to 14kHz to help reduce the audible noise from the motor.
n Automatic restart: Can be programmed to automatically restart upon application of power.
n Skip frequencies: Two skip frequencies are available to lock out critical frequencies that cause mechanical
resonance in the system.
n Isolation: Inputs and outputs are isolated and allow any speed reference signal to be accepted.
n PID setpoint control: Closed loop control to automatically maintain set point based on process control feedback
(AC400 only).
n NEMA enclosure choices: Choose either NEMA1, 4/12 or 4X (see page 60).
The AC300 and AC400 have over 55 programmable parameters that include: 4 or more ways to start and stop the
motor, forward and/or reverse rotation, two adjustable acceleration and deceleration times (0.1 to 3600 seconds), DC
injection braking time and voltage, maximum (120 Hz) and minimum frequency (0 Hz), current limit, motor overload,
fixed and acceleration boost, slip compensation, 4 preset speeds, skip frequencies, and many more. These units can be
programmed using the eight button keypad on the front of the drive enclosure, a remote keypad, a “point and click”
Windows software (Techlink) that runs on a PC and works through the RS485, or with Modbus. The drives are shipped
with default settings which shorten the time for setup requiring only a few adjustments in the program before the appli-
cation can be off and running.
OPTIONS: In addition to the many standard features these units have they also have an optional dynamic brake card
and resistor for those applications requiring quick repetitive stops, a second Form C auxiliary relay in an option card, and
a rugged NEMA 4 keypad mounting kit.
The AC300 and AC400 Series are full-featured, rugged, and compact micro drives priced to fit your budget. Choose the
AC300 or AC400 for your next AC, V/Hz drive application.
Part numbers and specifications on page 60.
The AC300 and AC400 Series variable frequency,
micro, V/Hz drive offers the widest range of voltages,
power ratings, and enclosure types. These drives
meet the toughest requirements from harsh environ-
ments to high torque loads. They are housed in a
heavy-duty steel enclosure for solid mechanical pro-
tection and electrical shielding. The AC300 and the
AC400 Series have many of the same features except
the AC400 has a built-in PID control feature which
allows for closed-loop control to automatically adjust
the motor speed to maintain the set point.
The AC300 and AC400 have a 16 character backlit
display for programming, drive status, and diagnos-
tics. They have 21 isolated inputs and outputs includ-
ing start, stop, 0-10VDC input, 4-20mA input,
10VDC supply for an external potentiometer, 12VDC
supply for an external relay, two open collector out-
puts, two analog outputs, three programmable
inputs, two relay outputs, and RS485 (RXA, TXB).
