Specifications... 7 Control Signal Connection (J2) The signal inputs on J2 are isolated inputs and can
receive control signals from other control devices or equipment so long as the COM
signal does not exceed 30Vdc with respect to earth ground.
+VS : External Power Source: +5VDC output for a potentiometer. The external load
on this supply should be 10Kohms or higher (500ua max.).
EN : Disable Control: External disable signal for the motor output. Connecting this
input to the com terminal will cause the DigiDrive to turn off power to the motor.
0-5V : Speed Control: Sets the output frequency of the drive proportionate to the input
voltage. If the voltage is below the enable threshold the drive output is disabled. A 0-
10V control source can be used by adding an external 100k resistor in series. (The
enable threshold will now be double).
4-20 : Speed Control:. Output frequency is proportional to current from 4 to 20mA.
Below 4mA drive is Off
COM: Common: Common signal for speed and disable signals.

Warnings
1. This product is an open frame design containing dangerous voltages. The
User is responsible for ensuring that the DigiDrive is safely installed and
wired for their particular application. When power is applied, the motor
output terminals, and all the components on the PCBs, should always be
regarded as high voltage, even if the Status indicator is Off.
2. Always remove power from the DigiDrive before making connections or
adjusting jumper settings. After switching power off, wait until all 3 LEDs
are completely extinguished before working on the drive or motor.
3. The control input signals (J2), are isolated from the line voltage. However,
incorrect wiring can violate the isolation between control inputs signals (J2)
and dangerous voltages on other parts of the circuit. The installer of this
product should check wiring carefully and perform a test (Hipot) to insure
that isolation exists between the control input signals and the AC line.
4. The DigiDrive is designed to operate in an ambient temperature of up to
40°C. The temperature of the heatsink depends on many factors including
airflow, orientation and operating profile. The user should ensure that the
heatsink temperature does not exceed 80°C worst case. In applications
where the heatsink may be touched by the end-user, regulations may limit
the maximum temperature to 70°C.
5. This
drive
is
not recognized for use as a motor protector. The attached
motor must have its own recognized over load protection device.
6. This drive is recognized for use in an environment of pollution class 2 and
must be mounted in a suitable enclosure.
7. This product cannot be used in any equipment intended for life support.
Welcome To Anacon Systems DigiDrive II
The DigiDrive II is a speed controller for single phase motors.
It allows the motors speed to be changed while consuming minimum electrical
power. This manual provides information on connections, safety, specifications
and troubleshooting. A separate manual exists for information concerning the
optional Dash Drive configuration system.

Description of Components
Power Drive Block: L shaped board containing power transistors.
Attached to heatsink with three screws. Has no user adjustable
components or terminals.
Control Board: Contains all user terminals. 6.5 amp units contain 3
large round capacitors. 4.0 amp units contain 2 large round capacitors.
Power Indicator: Green LED mounted on control board adjacent to
Motor terminals. Marked PWR. Lighted whenever sufficient line
voltage is available for operation. Blinking or off state indicates input
voltage is insufficient
Fault Indicator: Red LED mounted on control board. Marked FLT
Flashes fast and dim to indicate system OK. Flashes bright and slow to
indicate drive has turned itself off. See Fault Codes section of this
manual.
Status Indicator: Green LED mounted on control board adjacent to
Serial port. Marked STAT. Lit whenever power is being sent to the
motor.
Serial Port: Jack mounted on control board which accepts mini stereo
plug. Used in conjunction with optional Configuration Kit.. Cannot be
directly connected to any other equipment. (Is not RS 232 standard.)
Control Connector J2: Green, mounted on control board, 5 terminal.
Used to connect potentiometer or other control equipment such as a
PLC. Tighten to .95-1.3 in-lbs
Motor / Line Terminals: Blue, mounted on control board, 6 terminal.
For connection driven motor and input line. Tighten to 4.3-4.6 in-lbs
CAUTION: these terminals are at dangerous voltage.

Changing Parameters
The DigiDrive is shipped ready to run a fan load and be controlled from a potentiometer.
It can be changed to operate different types of loads, have different acceleration times,
use a different speed range, etc. These parameters can be changed using either the
jumper method or the User method. There is a jumper on the circuit board, marked
config, which selects which method will be used.
Jumper Method. To use this method, the Config jumper should be set to the DEFAULT
position. The DigiDrive has two other jumpers on its circuit board that can now be used
to adjust Accel rate and Boost profile. For faster acceleration, insert jumper J13. For
more starting torque, insert jumper J12.
User Method. With this method, a personal computer or other serial controller can be
used to change parameters. To use this method the Config jumper must be set to USER.
Many more parameters are available with this method. An optional configuration kit
(P/No DD-CFG) connects the DigiDrive to a PC/serial controller through a serial data
link. Anacons DashDrive Windows Software provides several screens to change
parameters, such as, acceleration, V-F profiles, etc. Once configured, DashDrive stores
the parameters in the DigiDrives non-volatile memory and the programmer is no longer
required. A separate manual is available for the DashDrive program. If the Config
jumper is in the DEFAULT position, the drive will accept and use parameter changes
from the PC/serial controller but will revert back to the jumper setting when the power is
turned off.

Terminals Using the DigiDrive
Step 1 Read Instructions and Warnings
Before connecting power to the DigiDrive, read all warnings listed at the
beginning of these instructions. If you have questions, contact Anacon
Systems or your distributor for assistance.
Step 2 Mounting
The correct mounting orientation for the DigiDrive is on a vertical surface with
the length of the fins running vertically. Observe all warnings listed in these
instructions.
Step 3 Connection
Refer to the Connection drawing. Wire the control first, then the motor.
Connect the line last.
The command (0-5v or 4-20ma) input can be driven by either a local
potentiometer, remote potentiometer, an external voltage source or a 4-20mA
current source. Refer to the connection drawing for wiring information. If 4-
20mA is being used, the 0-5v input will become inactive automatically as soon
as a current greater 2ma is input
.
Step 4 Testing
After checking wiring, power the drive and test operation over the full speed
range.
If a potentiometer is being used, advance the knob slowly. The Status LED will
light indicating that the drive has started. The motor load should start to rotate.
If the Red Fault (FLT) Indicator lights, check the fault code before removing
power.
The practical motor speed range will depend on the motor and the application.
The Default profile should work in most simple applications. Some applications
may require more advanced configuration using a PC to customize V-F curves,
ramp rates etc.
Step 5 Application Configuration
If the motor stops running, does not run properly, or if the Fault indicator
starts to flash slowly, It may be necessary to change the parameters that
the DigiDrive uses to control the motor speed and voltage.
After removing power and waiting for all Indicato
