Fault Protection
The 7080 provides protection against reversed power supply polarity, motor short
circuits and excessive drive temperature. Under normal operation, you should see
one red light, the power light.
If you see no lights either the fuse is blown or you do not have power applied to
the drive. If the fuse blows, the + and – leads to the power supply may be reversed.
Check to see if the wires connecting the power supply to the drive are reversed.
If you see a yellow "short" light the 7080 has detected an overcurrent
condition and shut down the amplifiers. The first thing you should do is switch the
power supply off. Check the motor wiring carefully. Make sure that the connections
to the drive are secure and that any unused motor leads are insulated from the drive
and power supply and from each other. Check the motor leads for shorts between
phases or shorts to ground.
If you see a yellow "temp" light the 7080 has overheated. This means you
need more air flow around the drive or additional heat sinking.
Mounting the Drive
You can mount your drive on the wide or the narrow side of the chassis. If you
mount the drive on the wide side, use #6 screws through the four corner holes. For
narrow side mounting applications, you can use #6 screws in the two side holes.
The 7080 drive will dissipate heat better if you mount it on the narrow
side. Please use narrow side mounting whenever possible.
7080 Drive
DC Power Supply
If you need information about choosing a power supply, please read Choosing a
Power Supply located in the back of this manual.
Connect the motor power supply + terminal to the driver terminal labeled "+V".
Connect power supply – to the drive terminal labeled "V–." Use 18 gauge wire. Be
careful not to reverse the wires.
!
When connecting the motor to the driver, be sure that the
motor power supply is off. Secure any unused motor leads
so that they can't short out to anything. Never disconnect
the motor while the drive is powered up. Never connect
motor leads to ground or to a power supply!
You must now decide how to connect your
motor to the drive. The lead colors shown
are for Applied Motion Products motors.
Four lead motors can only be connected
one way. Please follow the sketch at the
right.
Six lead motors can be connected in series
or center tap. In series mode, motors
produce more torque at low speeds, but
cannot run as fast as in the center tap
configuration. In series operation, the motor should be operated at 30% less than
the rated current to prevent overheating. Winding diagrams for both connection
methods are shown on the next page.
The amplifiers in the 7080 generate heat. To operate the drive continuously at
maximum power you may need additional heat sinking or forced air cooling. Never
use your drive in a space where there is no air flow or where other devices cause the
surrounding air to be more than 50 C. Never put the drive where it can get wet or
where metal particles can get on it.
