Bit 15: Reserved –
State ignored.
Bits 14 - 7: Reserved – Must equal zero.
Bit 6: DC_Sync – When set to “0”, the SMD17K begins a move as soon as data is read from the EtherCAT
Slave Controller (ESC). When set to “1”, the SMD17K will synchronize the start of a move on the
SYNC0 output of the system’s Distributed Clock. This allows you to synchronize the start of moves
over multiple devices.
Bits 5 - 2: Reserved – Must equal zero.
Bit 1: IN2_Active_Level – Determines the active state of Input 2. Set to “0” if your sensor has Normally
Closed (NC) contacts and the input is active when there is no current flow through it. Set to “1” if
your sensor has Normally Open (NO) contacts and current flows through the input when it is active.
Bit 0: IN1_Active_Level – Determines the active state of Input 1. Set to “0” if your sensor has Normally
Closed (NC) contacts and the input is active when there is no current flow through it. Set to “1” if
your sensor has Normally Open (NO) contacts and current flows through the input when it is active.
If you are not using the input, sets its Active_Level bit to “1”. The input will always report as
inactive in the network data.
Range of Values for Configuration Word 1
Valid values for Configuration Word 1 are: 0, 1, 2, 3, 64, 65, 66, and 67. (0x0000, 0x0001, 0x0002, 0x0003,
0x0040, 0x0041, 0x0042, 0x0043)
Notes on Other Configuration Words

Changes to the Idle Current only take effect at the end of the first move after re-configuration .
Invalid Configurations
The following configurations are invalid:
1) Setting any of the reserved bits in the configuration words.
2) Setting any parameter to a value outside of its valid range.
3) Configuring the two inputs to have the same function, such as two CW Limit Switches. (An error
does not occur if both are configured as General Purpose Inputs.)
4) Setting the Stall Detection Enable Bit without configuring the SMD17K to use its built in encoder.
5) Setting the Input Configuration bits for any input to “111”. See table R5.3 on page 57 for more
information.

IGNORED: Bit can equal either value.
