states of the axis. When changing this parameter from RMCTools, the software will

automatically do this for you. This may cause a halt on the axis, which is expected.
See the MDT/SSI Configuration Register for details about the register containing these

bits.

9.2.2.2.23.4. SSI Format

Type: Axis Parameter Register

RMC70 Address: %MDn.10/9, where n = 12 + the axis number

RMC150 Address: %MDn.10/9, where n = 24 + the axis number

System Tag: _Axis[n].MDTSSICfg.GrayCode

How to Find: Axes Parameters Pane, Setup tab: Primary Control Setup

Data Type: Bit - see below

Description

This parameter is valid only on axes with SSI feedback. You must set this parameter to

match your SSI transducer or encoder. The following options are available:

Binary

Gray

Changing this Parameter
Because this parameter affects motion, the axis must be disabled or in Direct Output

before writing to this parameter. The Enabled and Direct Output Status Bits indicate these

states of the axis. When changing this parameter from RMCTools, the software will

automatically do this for you. This may cause a halt on the axis, which is expected.

Format Details

This section is primarily for addressing the SSI Format parameter when communicating

with the RMC from an external device. This information is not necessary when configuring

the SSI Format in RMCTools.
The SSI Format is selected with bit 9 in the MDT/SSI Configuration Register. This bit

corresponds to the SSI Format as shown in the following table:

Bit 9 SSI Format
