TECHNICAL NOTE
<RDERROR> Axis Fault Condition:
The following table outlines several situations that may cause an error. The block error
can be cleared by the EXECUTE bit going low.
Internal error bit Cause Attention
IDerror
AB000003 RDA ERROR Will go high if Error ID <> 0 (MW3**81)
fault
AB00012 Servo Alarm If Servo alarm condition exists. Sets RDA
Error ID (MW3**81) bit 7 on if error state
exists.
axisInErr
AB00000F The axis number
entered on the
input is not an
acceptable value The functions blocks can only control 1 to
16 axis. Any value greater or smaller then
this will cause an error. This does not set
the RDA Error ID.
<RDERROR> Working Registers
This table outlines the data in the five registers used by the function block. There is not
usually any need for the user to access any of these bits directly.
Register No. Type Name Description
AW00000
Bit 0 IN execute EXECUTE input (XB000000)
Bit 1 Working inrngAxis Goes high for one scan if Axis input is in range.
Bit 3 Working IDerror
Goes high if RDA Error ID (MW3**81) <> 0.
Bit 7 OUT running Directly controls YB000000 (RUNNING Output)
Bit A Working oneshotA Reserved
Bit B Working firstPass One shot coil to initialize RDA of blocks execution
Bit F Working axisInErr Goes high for one scan if Axis input is out of range.
AW00001
Bit 2 OUT fault Directly controls YB000002(AXIS-ERR Output).
AW00002 Working rdaMult Value for address offset to locate proper RDA
AW00003 Working Revision Revision Level of the function block.
