TIP - Tips indicate information that should make a procedure easier or more
efficient.
General Safety Precautions Warnings
Important safety information follows. Please read and understand all
precautions listed below before proceeding with the specification, installation,
set-up or operation of your Smart Trac AC1. Failure to follow any of the
following precautions may result in personal injury or death, or damage to the
equipment.
WARNING - ESD
The Control Printed Circuit Board (PCB) employs CMOS
Integrated Circuits that are easily damaged by static electricity.
Use proper ElectroStatic Discharge (ESD) procedures when
handling the Control PCB. See Smart Trac AC1 Technical Manual
for details. Failure to comply may result in damage to equipment
and/or personal injury.
Important Warranty Information.
Do not modify your Smart Trac AC1, its components, or any of the procedures
contained in the technical documentation supplied by MagneTek. Any
modification of this product by the user is not the responsibility of MagneTek
and will void the warranty.

Smart Trac PG Card
General Capabilities
SMART TRAC PG Card
Closed-loop Control
Position Control
Digital Input
Analog Input
A Smart Trac PG Card added to your Smart Trac AC1 provides closed loop flux
vector control and closed loop speed control. With the card, 5 V to 12 V
differential quadrature signals at a rate of up to 300 KHz with a 540 ohm input
load may be input. Quadrature phasing of encoder inputs is 90 degrees +/- 22
degrees maximum at 300 kHz. Follower applications may use a second encoder
input. A 12 VDC power supply rated at 200 mA supplies power to the encoder.
The Smart Trac PG Card also provides position control. Start and stop signals
control two 32-bit counters that can be used to measure the rotation of either
start or stop signals. The Start and Stop signals can come from one of three
sources: the marker pulse of either encoder; one of the two digital inputs (i.e.,
connected to proximity switches); or software command.
The two 12 VDC input signals can be used as general purpose inputs if not
needed for position control.
Two analog input channels can accommodate either load cells or potentiometers.
The input voltage range for each channel is ± 600 mV or ± 10 Volts, selectable.
The Smart Trac PG Card also supplies:
• an A/D converter with 12 bits of resolution.
• a +5VDC, 50 mA power supply.
• reference voltages of +10VDC and -10VDC, both rated at 10 mA.
Quick Start
1. Remove all Smart Trac cards except the Smart Trac Inverter and CPU
cards per instructions in "Installing the Smart Trac PG Card. "
2. Install the Smart Trac PG card as the second card of the card stack.
3. Make connections to the PG card terminal blocks per information
contained in this manual and your situation.
4. Replace all other cards per the instructions in "Installing the Smart Trac
PG Card."
5. Power up and test functionality of your Smart Trac AC1, including that
of the Smart Trac PG card.
Keep electronic circuit boards in ElectroStatic Discharge (ESD)
protective bags when not being handled. Use proper ESD
procedures (including an ESD wrist strap) when handling circuit
boards. Failure to comply may result in damage to equipment.
When working with an ElectroStatic Discharge (ESD) sensitive device, you
should be grounded at all times. The easiest and most common way to provide
this ground is to use an approved ESD wrist strap. The strap is secured to your
wrist with a wire attached to the strap and clipped or taped to the chassis of the
unit being worked on. Any static is dissipated through the wire to ground,
greatly reducing the possibility of damage to the device.
It is a good idea to touch the chassis with your finger before handling any
electrostatic device. Any static electricity will be discharged to chassis ground
and will not be transferred to the device.
Always store devices (cards, other electronic components) in ESD protective
bags when not being handled.
Remove the protective shipping and packing material from the card. Ensure
contact wedges and other shipping devices have been removed.
Installing the Smart Trac PG Card
The Smart Trac PG Card must be positioned above the Smart Trac CPU card on
the Smart Trac AC1 card stack.
NOTE: If replacing or adding a Smart Trac PG card to an existing Smart Trac
card stack, see Appendix D – "Removing the Smart Trac Card Stack" before
continuing.
1. Power off the Smart Trac AC1. Disconnect it and tag it as "Out of
Service". Perform this and all other steps required to remove all cards
located in a stack position above the PG Card. See "Appendix D –
Removing the Smart Trac Card Stack"
2. To replace the PG card, orient the PG card so that the PC/104
connector and the J2 connector align with the PC/104 connector on the
Smart Trac CPU card and the 4CN connector on the Inverter Control
board. Be careful to align the PC/104 connector pins with the
receptacle on the Smart Trac CPU card so the pins don’t bend when the
card is pushed into place.
3. Gently but firmly push the Smart Trac PG card onto the Smart Trac
CPU card. Make sure connecting pins are in alignment and J2 mates
with 4CN before pushing the two boards tightly together. Secure the
card using four (4) metal standoffs and one (1) plastic standoff.
4. Replace the Smart Trac PS or Ethernet card and other cards by
reversing the procedures described in the Appendix "Removal of the
Smart Trac Card Stack."
• Two encoder inputs for closed loop flux vector control, closed loop
speed control and position control.
• Digital inputs (if not needed for position control).
• Analog inputs to accommodate load cells or potentiometers.
Port Address
The Smart Trac PG card uses a port address of "1". Hardwired on the card, the
address may be overridden if two Smart Trac PG cards must be used. Contact
MagneTek for details.
Encoders
Connect encoders at Terminal Block J3 (feedback encoder input) or at Terminal
Block J5 (follower encoder input). Only the feedback encoder Terminal Block
J3 provides a 12 volt power supply for the encoder.
Channel 0 - feedback encoder
Use Channel 0 for the encoder of the motor connected to the Smart Trac AC1. It
provides feedback to both the Smart Trac AC1 inverter control card and CPU.
Terminal Block J3 provides these connections for differential A, B and Z inputs
and a 12-volt @200ma power supply. A and B are used for speed and position
control. Z is used for position start and stop only.
Channel 1 - follower encoder
Use Channel 1 for another feedback source. It only provides feedback for the
Smart Trac CPU card. Terminal Block J5 provides connections for differential
A, B and Z inputs.
Digital Inputs
Two +12 Volt digital inputs are located on Terminal Block J4 for proximity
switch inputs (LI0 and LI1). Each of the digital inputs sinks 10mA and may be
used for position start and stop, or as a general purpose input.
