NOTICE
USE CORRECT INSTRUCTIONS WITH SMARTPAC PRO/WPC 2000 INTEGRATION
If you are installing the overrun limit switch for the SmartPAC PRO with WPC 2000 integration, you
must follow the in
structions in the Setting the Top Stop “On” Angle and Installing the Overrun
Magnet section in Chapter 2 of the SmartPAC PRO with WPC 2000 user manual. The overrun limit
switch feature is required when WPC 2000 is integrated with SmartPAC PRO. Do not refer to the
steps below if you are installing the overrun limit switch.
SmartPAC PRO compares the timing of this signal with the angle of the resolver. If the resolver angle
changes relative to this signal, SmartPAC PRO knows that the resolver drive has slipped or broken or
the resolver itself has failed and issues an Emergency Stop command, simultaneously displaying an
error message.
Find a mounting location that allows the magnet to move past the switch once on every stroke and
close enough for the switch to sense the presence of the magnet. A gap between switch and magnet of
between 1/8 in. and 3/16 in. (about 3 – 5 mm) is recommended. The position sensor must be mounted
so that it is not connected to the resolver shaft or sprocket or any of the drive components leading to
the resolver and continue to operate if the resolver or its drive mechanism fails. The position sensor
must be installed only after the resolver is zeroed.
To generate an adequate position signal, the magnet should be mounted so the switch senses it for at
least 10

to 15

of the stroke. For best results at higher press speeds, mount the magnet on a shaft of 2
in. to 3 in. (about 50 – 75 mm) diameter. As shown in Figure 2-18, the larger the diameter of the
shaft, the shorter the “dwell,” the period during which the switch senses the magnet. To obtain a
longer dwell, therefore, mount the magnet on a shaft of smaller diameter.

To install the position sensor, do the following:
1. Make sure that the resolver has been zeroed (see Zeroing the Resolver , page 42).
2. Turn on power to SmartPAC PRO.
3. Turn the PROG/RUN keyswitch to PROG. The Main Program Menu displays.
