WARRANTY AND LIMITATION OF LIABILITY
Includes software provided by Pacific Scientific
Pacific Scientific warrants its motors and controllers (“Product(s)”) to the original
purchaser (the “Customer”), and in the case of original equipment manufacturers or
distributors, to their original consumer (the “Customer”) to be free from defects in
material and workmanship and to be made in accordance with Customer’s
specifications which have been accepted in writing by Pacific Scientific. In no
event, however, shall Pacific Scientific be liable or have any responsibility under
such warranty if the Products have been improperly stored, installed, used or
maintained, or if customer has permitted any unauthorized modifications,
adjustments, and/or repairs to such Products. Pacific Scientific’s obligation
hereunder is limited solely to repairing or replacing (at its option), at its factory
any Products, or parts thereof, which prove to Pacific Scientific’s satisfaction to be
defective as a result of defective materials or workmanship, in accordance with
Pacific Scientific’s stated warranty, provided, however, that written notice of
claimed defects shall have been given to Pacific Scientific within two (2) years
after the date of the product date code that is affixed to the product, and within
thirty (30) days from the date any such defect is first discovered. The products or
parts claimed to be defective must be returned to Pacific Scientific, transportation
prepaid by Customer, with written specifications of the claimed defect. Evidence
acceptable to Pacific Scientific must be furnished that the claimed defects were not
caused by misuse, abuse, or neglect by anyone other than Pacific Scientific.
Pacific Scientific also warrants that each of the Pacific Scientific Motion Control
Software Programs (“Program(s)”) will, when delivered, conform to the
specifications therefore set forth in Pacific Scientific’s specifications manual.
Customer, however, acknowledges that these Programs are of such complexity and
that the Programs are used in such diverse equipment and operating environments
that defects unknown to Pacific Scientific may be discovered only after the
Programs have been used by Customer. Customer agrees that as Pacific
Scientific’s sole liability, and as Customer’s sole remedy, Pacific Scientific will
correct documented failures of the Programs to conform to Pacific Scientific’s
specifications manual. PACIFIC SCIENTIFIC DOES NOT SEPARATELY
WARRANT THE RESULTS OF ANY SUCH CORRECTION OR WARRANT
THAT ANY OR ALL FAILURES OR ERRORS WILL BE CORRECTED OR
WARRANT THAT THE FUNCTIONS CONTAINED IN PACIFIC
SCIENTIFIC’S PROGRAMS WILL MEET CUSTOMER’S REQUIREMENTS
OR WILL OPERATE IN THE COMBINATIONS SELECTED BY CUSTOMER.
This warranty for Programs is contingent upon proper use of the Programs and
shall not apply to defects or failure due to: (i) accident, neglect, or misuse; (ii)
failure of Customer’s equipment; (iii) the use of software or hardware not provided
by Pacific Scientific; (iv) unusual stress caused by Customer’s equipment; or (v)
any party other than Pacific Scientific who modifies, adjusts, repairs, adds to,
deletes from or services the Programs. This warranty for Programs is valid for a
period of ninety (90) days from the date Pacific Scientific first delivers the
Programs to Customer.

1 Overview of the OC950
Programmable Option Card
Introduction This chapter introduces the OC950 Programmable Option Card.
Topics covered are:
•OC950 Overview
•How to Use this Manual
•Warranty Information
1.1 OC950 Programmable Option Card Definition
OC950 overview The OC950 is an option card that is installed in the option card
slot of a Pacific Scientific SC900 Series Servo Drive. Combined,
the SC900 and OC950 create the SC950. It provides stand-alone,
single-axis programmable positioning capability to a high
performance, digital servo drive.
The SC950 inherits all the advanced, high-performance
functionality as well as the small package size of the SC900
platform. The SC950 also inherits all the hardware resources of
that platform, including 6 points of bi-directional discrete I/O,
two analog outputs, one analog input, one encoder input port and
one encoder output port. The SC900 platform also provides two
high speed registration inputs.
Resources provided on all varieties the OC950 include
twenty-one points of bi-directional discrete I/O and an
RS-232/RS-485 serial communications port.
The OC950 provides for direct connection to Opto22 Industrial
I/O mounting racks and industrial I/O modules with the use of the
CA950-IO adapter module.

OC950 Hardware
Varieties
Two optional memory (NVRAM: nonvolatile random access
memory) configurations are available, 32kx8 or 128kx8. NVRAM
is battery backed, with a ten year life, and unlimited amount of
write cycles. The memory provides storage for the user programs.
A PacLANNetwork interface is offered as an OC950 option.
PacLAN supports 2.5 Mb/sec communications between a cluster
of SC950 drives. The port will be compatible with standard
ArcNET products using 93 Ωcoax cable in a bus configuration.
Standard
version
Combinations of the two memory offerings and the PacLAN
option results in four standard versions of the OC950:
OC950-501-01 Base 950 Option Card 32kx8 NVRAM
OC950-502-01 Base 950 Option Card 128kx8 NVRAM
OC950-503-01 Base 950 Option Card 32kx8 NVRAM + PacLAN
OC950-504-01 Base 950 Option Card 128kx8 NVRAM + PacLAN
Enhanced
Version
In addition, there is an Enhanced version of the OC950 which
supports additional features, including MODBUS and camming.
OC950-601-01 Enhanced 950 Option Card 32kx8 NVRAM
OC950-602-01 Enhanced 950 Option Card 128kx8 NVRAM
OC950-603-01 Enhanced 950 Option Card 32kx8 NVRAM + PacLAN
OC950-604-01 Enhanced 950 Option Card 128kx8 NVRAM + PacLAN

1.2 How to use this manual
Chapter 2, “Getting Started”, is a step-by-step guide allowing you
to configure an SC950 and run your motor within a few minutes.
It is strongly recommended that you go through Chapter 2 first.
This will give you a feel for using the SC950 and lay the
framework for reading the other chapters. Chapters 3 through 5
should be read thoroughly to gain the most from the OC950.
1.3 Warranty
The Pacific Scientific OC950 has a two year warranty against
defects in material and assembly. Products that have been
modified by the customer, physically mishandled, or otherwise
abused through miswiring, and so on, are exempt from the
warranty plan.
Warning
If the continuous current rating of the drive is greater than the
continuous current rating of the motor that it is being used
with, then it is possible to cause significant damage to the
motor. Pacific Scientific may not honor the warranty of the
motor if it is run under these conditions.

2 Getting Started
Introduction This chapter provides a step-by-step introduction to creating a
new program. This procedure uses the minimum possible
equipment to run an unloaded motor and sets motor speed from a
PC’s serial port. It is strongly recommended that all first time
users go through this procedure to become familiar with the
OC950 and the 950IDE PC interface software before installing
the servo system in a machine.
2.1 Setting Up the Hardware
What you will
need
To go through this product introduction procedure you will need
the following items.
•SC900 Base Servo Drive
•OC950 Programmable Option Card
•Appropriate Brushless Motor with nothing attached to the
shaft
•PC Running Windows 3.1 or Windows95/NT
•950IDE Floppy Disk
