Delta RMC151 - Manual (Page 944)

RMC70/150 and RMCTools User Manual
Type: Axis Parameter Register
RMC70 Address: %MDn.10/8, where n = 12 + the axis number
RMC150 Address: not available
System Tag: _Axis[n].MDTSSICfg.SSI
How to Find: Axes Parameters Pane, Setup tab: Primary Control Setup
Data Type: Bits - see below
Description
This parameter is valid only on MA axis modules on the RMC70. The Feedback Type
parameter specifies the feedback type of the axis. The following options are available:
• MDT
Magnetostrictive Displacement Transducer. Supports Start/Stop rising edge,
Start/Stop falling edge, and Pulse-Width Modulated (PWM).
• SSI
Synchronous Serial Interface.
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 Feedback Type parameter when
communicating with the RMC from an external device. This information is not necessary
when configuring the Feedback in RMCTools.
The Feedback Type is selected with bit 8 in this register. This bit corresponds to the
Feedback Type as shown in the following table:
Bit 8 MDT Type
0 MDT
1 SSI
See the MDT/SSI Configuration Register for details about the register containing these
bits.
