How DiPro 1500 works
The resolver lets DiPro 1500 know where the crankshaft is
A key element of DiPro operation is that it always knows the position of the crankshaft
during the stroke. DiPro is connected to a resolver mounted on the press which turns one
to one (1:1) with the crankshaft. The resolver is similar to an electrical generator. It has a
lot of windings inside and works on the principle of inductance. The resolver has two
outputs. As the resolver turns the amplitude and the phase of the two ouptuts varies,
these signals are interpreted by DiPro 1500's electronics to determine the correct angle.
Thus, the purpose of the resolver is to tell DiPro where the crankshaft is at every point in
the stroke.
DiPro converts the resolver signal to the crank angle
DiPro's electronics convert the analog signal from the resolver at any point in its rotation
to a number. This number is the position of the resolver (and press crankshaft) in degrees.
Now let's say you expect to see a part eject from the die between 190° and 270° of every
stroke. You make this setting on DiPro. This is the ready signal—the degrees during the
stroke where you will expect your part ejection sensor to actuate. (We will tell you more
about sensors and ready signals later). Now DiPro knows when during the stroke to
expect a signal from the sensor (between 190° and 270°). You can set a separate ready
signal for each sensor.
DiPro 1500 checks for the sensor signal at the right time
When the press is running and the ram reaches 190°, DiPro checks for the signal from the
sensor. If it does not get a signal from the sensor before the ram reaches 270°, it sends a
stop command to the press.
DiPro 1500 makes many decisions simultaneously
DiPro can make decisions like this for up to six sensors at once. You can use sensors that
actuate on every stroke to signal the proper event has occurred (cyclic sensors). You can
also use sensors that actuate only when a malfunction occurs (static sensors). If you have
the cam timing option installed, DiPro can also simultaneously control four cam
channels. It can turn a channel on and off at the exact point in the stroke you set. Because
DiPro is a microprocessor, it can monitor or control all these different functions during a
press stroke even for very high speed presses. And it saves all your settings so you do not
have to make them over and over. You just reload them when the tool is used again.
DiPro 1500 stops press when a malfunction occurs
When a sensor signals a malfunction, DiPro signals the press to stop (either an
emergency stop or top stop—your choice). The display tells you which sensor signalled
the malfunction. After you correct the problem, you reset DiPro using the RESET key.
Then you can continue to make parts.
DiPro 1500 can also send a stop signal when one of its counters reaches the preset value.
