Introduction

Detailed instructions on how to use the keyboard and display are provided in Chapter 3.

Resolver-based Operation

SmartPAC 2 is connected to a resolver mounted on the press that turns one to one (1:1) with
the crankshaft. Like an electrical generator, the resolver has internal windings and works on
the principle of inductance. As the resolver turns, the amplitude and phase of its two outputs
vary. SmartPAC 2 converts this analog signal to a number that specifies the position of the
press crankshaft in degrees.

SmartPAC 2 Settings

You can make the following settings, using the keys on the SmartPAC 2 keyboard:

•

Assign tool numbers.

Settings for each tool are stored by tool number, which you

assign to identify and access the tool when you want to program or load it. You specify in
Initialization mode whether to use numeric or alphanumeric tool numbers in programming.

•

Load settings by tool number.

SmartPAC 2 saves all counter, sensor (if DiProPAC is

installed), cam switch (if ProCamPAC is installed), and other press settings in its electronic
memory. To use tool settings again, you recall them by selecting the tool number from the
Tool Manager display. SmartPAC 2 retains tool settings even when the power is off.

•

Record tool information for each tool number.

With this option you can record up

to 30 characters of information, such as installation notes, for each tool.

•

Protect settings with lockout and optional password security.

Using SmartPAC

2’s Security Access Menu in Initialization mode, you can lock many of the settings in Run
mode, preventing anyone without access to the Program/Run key from altering Run
settings. You can also require that the user enter a password in order to change settings. To
prevent unauthorized changes to SmartPAC 2 setup, you can require a special password for
access to the Main Initialization Menu.

•

Set Brake Monitor.

You set the brake monitor stop time limit to compensate for normal

brake wear and to provide a warning when the brake needs service. When you make a time
setting that is longer than the actual stopping time and the press reaches that stop time limit,
the brake monitor disables the press, alerting you that your brake requires service. In
addition, the Brake Warning LED on the SmartPAC 2 front panel (see Figure 1-1, page 1-3
for location) flashes when press stopping time approaches within 10 milliseconds of the
stop time limit, allowing you to schedule brake maintenance before the press has to be
disabled.

•

Set counters.

SmartPAC 2 provides counters to keep track of the number of strokes

made by the press during each job, the number of good parts produced, and other desired
statistical information. The stroke counter increments at each press cycle. The good parts
counter increments only when the die protection or tonnage monitoring option does not
generate a fault. Three batch counters can be set to either top-stop the press or signal
programmable limit switch (PLS) outputs when their presets are reached. The total hits
counter counts all hits on a tool, and keeps track of the last recorded number for the
previous job. With the optional Advanced counter mode, you can set the good parts
