How to replace and rezero the resolver
After you have successfully installed the new resolver (discussed in the section
"Installing the resolver" in Chapter 2, you will need to rezero.
1. Go to the "Resolver Zero" screen. Notice the value in the LCD display (e.g.
"Current Resolver Zero Position is 356" reflecting the original zeroed position) may
not match the "unzeroed" angle position shown in the LED display.
2. Move the ram so that the crank-angle position shown in the LED display matches as
close as possible to the value appearing in the LCD display. Remember that the
readout must be between 330° and 30°.
3. Once you have done this, you can rezero the resolver. To do this, press ENTER.
4. Press RESET to go back to the Initialization menu when you are done.
Install position sensor (optional)
Installing a position sensor is optional. It must be installed only after the resolver is
zeroed. It is a mechanical proximity switch that monitors the resolver's position. It
consists of a magnet you mount on the crankshaft (or other shaft) and a stationary sensor
which is mounted just above the magnet so it detects the magnetic field every time the
shaft passes 0°. DiPro receives the signal from the sensor at 0° and checks that the
resolver is also signalling 0°. If it is not, this means the resolver is no longer rotating 1:1
with the press. The resolver drive has slipped or has broken or the resolver itself is
broken. DiPro will signal an emergency stop and display an error message.
To install the position sensor:
1. First you must load a tool number. This is so you can switch DiPro to Run mode
and see the angle of the crankshaft in the LED readout. If you have not made any
settings for a tool, you will have to key in some settings. This is why we told you
to become familiar with the DiPro displays before starting installation. It does not
matter what settings you make for now since no die is in the press. You can
simply key in a tool number and make some counter settings. You can create any
settings, then delete or change them later.
2. After loading a tool number, switch to Run mode (that is, set program/run key to
"run", set initialization switch inside DiPro to "run").
3. Check the number in the LED readout. If it is not zero, inch the press until the
readout shows zero. The press must be at zero resolver degrees before the
position sensor can be installed.
NOTE:
If the numbers in the readout decrease as you run the press instead of
increasing (that is goes from 359°, 358°, 357°, … to 0° instead of 0°, 1°, 2°, … to
359°), swap the black wire and yellow wire (terminals 2 and 5) on connector
TB105.
4. Now shut off power to DiPro and the press control. You are ready to install the
position sensor.
