CHAPTER 7
NETWORK DATA FORMATS
Modes of Operation
The SD17060E has two operating modes that is controlled by a single bit in the Network Output Data sent to
the drive. You can switch between modes by changing the state of this bit.
Configuration Mode
The SD17060E will always power up in this mode. Configuration Mode gives you the ability to select the
proper configuration for your application without having to set any switches. The SD17060E must be config-
ured on every power up. Additionally, the motor will not receive power until the drive is configured properly.
Command Mode
This mode gives you the ability to program and execute stepper moves and reset errors when they occur. The
SD17060E must be programmed with a valid configuration before it will allow you to switch to this mode.
Multi-Word Format
Many of the hosts that can be used with the SD17060E only support 16 bit integers, which limits the range of
values from -32,768 to 32,767 or 0 to 65,535. Many parameters of the SD17060E exceed this range. These
parameters are transmitted in two separate words. The table below shows how values are split. Note that neg-
ative values are written as negative numbers in both words.
Table 7.1 Multi-Word Format Examples
This chapter covers the formats of the Network Output Data used to configure and command the
SD17060E as well as the formats of the Network Input Data that contains the responses from the
drive. The SD17060E requires ten 16-bit words (20 bytes) for Output Data as well as ten 16-bit
words of Input Data.
