Installation
If the ram is already at top dead center (TDC), perform the Setting the Resolver Zero Position
procedure, below. Otherwise, first inch the ram to TDC, following the Moving the Ram to Top
Dead Center (TDC) procedure, next.
Moving the Ram to Top Dead Center (TDC)
If the ram is not at TDC, you must first inch the press to 0
°
± 2
°
before you can zero the
resolver. Since SmartPAC 2 is now connected to your stop circuits, you must load a tool in
order to inch the press.
1.
Access Program mode and create a new tool, following the steps in Creating a New Tool,
page 5-3.
2.
Enter a counter preset of 10,000 for the tool, following the directions in COUNTERS,
page 5-9.
3.
Load the tool, following the instructions in Loading a Tool, page 5-5.
4.
Turn the Program/Run key to RUN, and inch the press to 0
°
± 2
°
.
5.
When the press is at TDC, perform the next procedure.
Setting the Resolver Zero Position
To zero the resolver with the press at TDC, perform the following steps:
1.
On the SmartPAC 2 Main Initialization Menu (to access, press the 1 and CLEAR keys
simultaneously with SmartPAC 2 in Program mode), select RESOLVER ZERO. The
screen shown in Figure 2-24, page 2-37 displays.
2.
The value shown in the CURRENT RESOLVER ANGLE field should be as close as
possible to 0
°
, preferably between 355
°
and 5
°
, but anywhere between 330
°
and 30
°
is
acceptable.
If the current resolver angle is outside the range of 330
°
to 30
°
, loosen the tension on your
drive mechanism and turn the resolver shaft by hand (either direction is acceptable) until
the resolver angle is as close to zero as possible. Then tighten the drive mechanism,
making sure not to change the resolver angle reading.
3.
With the Resolver Zero display on the screen, press the F1 key.
SmartPAC 2 electronically adds or subtracts the offset, and the CURRENT ZERO
CORRECTION reading should change to match CURRENT RESOLVER ANGLE.
USE A DIAL INDICATOR TO DETERMINE TDC
Do not rely on the SmartPAC 2 display to indicate when the press has reached
TDC. Until the resolver is zeroed, displayed values are inaccurate. Use a dial
indicator or some other means to determine 0
°
.
