Chapter 3 Configuring the Ultra3000 Drive
Machine Cycle
Enable or disable a Single-Turn Absolute encoder.
• Enabled: to cause the SRS encoder to be used as an absolute
feedback device
• Disabled: to cause the SRS encoder not to be used as an
absolute feedback device. (Default)
Note: This parameter is visible only if the offline motor selection
or online motor has an SRS/SRM encoder.
Enable or disable Position Rollover:
• Enabled: to cause the position variable to rollover to zero when
it exceeds the specified size. (Default)
• Disabled: to cause the position variable to rollover only when it
exceeds 2147483647 counts, or its equivalent in other units.
Note: This parameter is disabled when Single-Turn Absolute is
enabled.
Size: Type a rollover value in counts. This is an integer at which
the next increment of a position variable will be the value of zero
(0).
Note: This parameter is disabled when Single-Turn Absolute is
enabled, and is automatically set to one revolution.
Communications
Drive Address The drive's communication port address - an integer from 0 to 255
- used in multiple axis applications. For single axis applications,
this value is usually set to 0. The drive must be reset before it
recognizes an edited drive address.
Note: Communication port parameters can be set in the PC
Communications Setup dialog box, that is opened using the Tools
menu Serial Port command.
Broadcast Address The address used by a host PC or PLC to issue a single broadcast
command to all connected Ultra3000 drives. The drive does not
send a response to commands received with the broadcast
address.
Note: If a drive's Broadcast Address and Drive Address are set to
the same value, that drive treats all commands as normal, point-
to-point commands, and sends a response to all commands it
processes.
Baud Rate Baud rate setting for the drive.
Note: The drive's Baud Rate must be the same as the PC's Baud
Rate (set in the PC Communications Setup dialog box) if the PC
and drive are to successfully communicate.
Refer to Serial Port Settings on page 22 for restrictions.
Frame Format Specify the drive's communication port packet framing format.
Note: The drive's Frame Format must be the same as the PC's
Format (set in the PC Communications Setup dialog box) if the PC
and drive are to successfully communicate.
