Supplemental Drive Information A-3
Communication
Configurations Typical Programmable Controller Configurations
Important: If block transfers are programmed to continuously write
information to the drive, care must be taken to properly format
the block transfer. If attribute 10 is selected for the block transfer,
values will be written only to RAM and will not be saved by the
drive. This is the preferred attribute for continuous transfers. If
attribute 9 is selected, each program scan will complete a write to
the drives non-volatile memory (EEprom). Since the EEprom
has a fixed number of allowed writes, continuous block transfers
will quickly damage the EEprom. Do Not assign attribute 9 to
continuous block transfers. Refer to the individual
communications adapter User Manual for additional details.

x Stop
(1)
(1)
A “0 = Not Stop” condition (logic 0) must first be present before a “1 = Start” condition will start the drive. The Start
command acts as a momentary Start command. A “1” will start the drive, but returning to “0” will not stop the drive.
0 = Not Stop
1 = Stop
x Start (1) (2)
(2) This Start will not function if a digital input (parameters 361-366) is programmed for 2-Wire Control (option 7, 8 or 9).
0 = Not Start
1 = Start
x Jog 0 = Not Jog
1 = Jog
x Clear Faults 0 = Not Clear Faults
1 = Clear Faults
x x Direction 00 = No Command
01 = Forward Command
10 = Reverse Command
11 = Hold Present Direction
x Local
Control 0 = No Local Control
1 = Local Control

11 = Use Present Time
x x x Reference
Select
(3)
(3) This Reference Select will not function if a digital input (parameters 361-366) is programmed for “Speed Sel 1, 2
or 3” (option 15, 16 or 17). Note that Reference Selection is “Exclusive Ownership” see
[Reference Owner] on
page 3-26 .
