The DIGIMAX
®
is a
crystal-based Speed or 
Ratio controller. It creates a 
train of pulses to command 
the movement of a motor 
when the drive is operating 
in digital speed mode. 
 
A suitable train of 
pulses applied at TB1 
terminal 11 (with respect to 
TB1-9) of the Model 1000 
commands the drive to turn 
the motor 3° for each pulse. 
However, the drive’s routine 
adjustments such as MIN 
SPEED, MAX SPEED, 
ACCEL, DECEL, and JOG 
SPEED are not functional. 
The DIGIMAX
supplies
these functions.
 
The wiring diagram at 
left shows all the basic 
connections to the 
DIGIMAX. Not all of them 
are necessary for all 
installations. For instance, 
external frequency is only 
needed for slave mode. 
 
The power, ground, 
and shield connections on DIGIMAX TB1 are necessary. The jumper from TB1-4 goes to a screw in the 
back plate. 
 
The pulse train comes from DIGIMAX TB1 terminals 11(+) and 10(-). It is applied to the Model 
1000AR TB1 terminals 11(+) and 9(-).
The MAN/AUTO switch may be left out. You can make a straight connection from DIGIMAX TB1-7 to
Model 1000AR TB1-10. Even this connection may be left off if the Current Controller board jumper JP1 is 
in the AF position (see page 27). 
The DIGIMAX control inputs are on TB2 terminals 5 through 10. These inputs require +24VDC. TB2
terminal 4 is the common connection for these isolated inputs. RUN (terminal 5) and ESTOP (terminal 7) 
are required for DIGIMAX operation. PRESET (terminal 6) is an optional second speed. The REVERSE 
input (terminal 8) must operate in conjunction with the drive’s reverse, if it is used. 
The EXTERNAL FREQUENCY input (TB2 terminals 13 and 14) is only used in the SLAVE mode. It is
used when the DIGIMAX is to follow another pulse train from another DIGIMAX or drive.
The input at DIGIMAX TB2 terminals 15, 16, and 17 in an optional motor load reading signal.
