to 65535 minus the "extra" counts. To correct for this effect the module calculates the "extra"
counts based on the number of transducer recirculations and subtracts them from the transducer
count. If the value of these bits and the transducer recirculations agree, the transducer count will
be slightly positive when the transducer is at its minimum position.
In some cases it may be desirable to set bits 12-15 to a value greater than the number of
recirculations to subtract additional counts, but if the value selected is too large it is possible to
get a position underflow condition. If this happens, the Position Overflow status bit will be set and
the Actual Position will be equal to the Offset parameter.
Rising-/Falling-Edge Selection - Bit 7
Use this bit to select the edge of a start/stop transducer’s waveform to be used. Notice that this
bit is ignored if a PWM transducer is selected as described above. Most transducers use rising
edges, but some transducers manufactured by Balluff are known to use falling edges.
Bit 7 Transducer Edge
0 Rising (default)
1 Falling
C.1.4 Configuration Bits - SSI Specific
Unused - Bits 7, 12-15
These bits are reserved for future use and should always be set to 0 on SSI axes. Refer to SSI
Configuration for details on configuring the RMC to use your SSI device.
C.1.5 Configuration Bits - Analog Specific
Analog Input Type - Bits 12-14
Use the following table to select the appropriate input range:
14 13 12 Analog Input Type
0 0 0 Voltage: 0V to +10V
0 0 1 Voltage: -10V to +10V
0 1 0 Voltage: 0V to +5V
0 1 1 Voltage: -5V to +5V
1 0 0 Current: 4mA to 20mA
For a description of the corresponding transducer count ranges, refer to the Counts topic.
Unused - Bits 7 and 15
These bits are reserved for future use and should be cleared on analog axes.
