TITLE: CORRECTIONS TO JUSP-NS500 USER MANUAL, SIE-C718-8
SUBJECT: JUSP-NS500 USER MANUAL CORRECTIONS
MOST RECENT EDIT - 2/7/05
DISTRIBUTION: ALL

Errors, corrections, and additions in this document are for User Manual # SIE­C718-8 printed in June 2003. See the back cover of the user manual to check the
date of printing. Also see ftp.yaskawa.com for supplemental documentation.

Section 4.3, Page 4-11, Addition, A reference unit is the smallest unit of
commanded motion. This manual will also use the word "step" interchangeably
with reference unit. A mechanical unit (such as inches) can have any number of
reference units as long as the ratio of PN810/Pn811 is within 100 to 0.01. Using
1000 reference units per mechanical unit will simplify the setting of speed
parameters, which are set in 1000 reference units per minute. For example if the
reference units are set to 0.001 inches, the speed parameters values will be in
inches per minute.

Section 4.3.3, Page 4-20, error, PN81A may be set to 0 or 1. The value 2 is not a
valid setting.

Chapter 5, omission, Note – The command and response messages contain
multi-byte data fields. The most significant byte in the data field occurs in the
lowest address. For example the decimal number 5000 is represented as:

Address Hex Bit
Byte 4 00 00000000
Byte 5 00 00000000
Byte 6 13 00010011
Byte 7 88 10001000

This format follows most Siemens PLC data formats and is sometimes referred to
as big-endian. Many controllers have a byte-swap function that can be used if the
controller data format is opposite.

Section 5.3.4 Page 5-21, addition, Command Code 1011 (Set Zero Point).
If using an absolute encoder, the current position of the motor is set as the zero
point by executing a Set Zero Point command. Execute the Set Zero Point

command by setting 1011 in the command code (byte 1, bits 0-3) and change the
C_STRT bit from 0 to 1. It is not necessary to make any settings in the data area
(bytes 2-7 =0). After the Set Zero Point is completed, an offset will be stored in
Pn809 (Zero Point Offset). Perform a Module Reset Command to the save the
value of Pn809 to flash ROM.

Section 5.4.4, Page 5-33, error, Target Speed 1-50 should be set in parameters
Pn940-Pn971.

Section 5.4.6, Page 5-38, error, The value in byte 1, bits 0-3 should read 01h
(h=hex) in the chart at the top of the page.

Section 5.4.7, Page 5-38, omission, Pn827 sets the feed speed for positioning
before the EXTP signal has been reached. Pn827 is also referenced in Chapter 4
parameter settings.

Section 5.4.7, Page 5-38, omission, Pn856 sets the polarity of the EXTP signal.
Pn856 is also referenced in Chapter 4 parameter settings.

Section 5.4.7, Page 5-39, error, The value in byte 1, bits 0-3 should read 02h
(h=hex) in the chart at the bottom of the page.

Section 5.4.8, Page 5-41, error, The value in byte 1, bits 0-3 should read 03h
(h=hex) in the chart in the middle of the page.

Section 5.4.9, Page 5-44, error, The value in byte 1, bits 0-3 should read 04h
(h=hex) in the chart at the bottom of the page.

Section 6.3.1, Page 6-10, error in the drawing, The EMSTOP input should be
wired to CN4, pin 9. See section 3.4.1, page 3-12.

Section 9.1, Page 9-28, addition, Cause B, Pn505 sets the allowable position
error. If Pn505 is too small an A.D0 can result. See the Sigma II user manual for
the SGDH amplifier.
