TECHNICAL NOTE
The following table outlines several situations that may cause an error. The block error
can be cleared by the ENABLE bit going low.
Internal error bit
Cause
Attention
rdaError
AB000004
The RDA is not
properly set up.
If Motor Rated Speed (MW3**73) or
Encoder resolution (ML3**74) is not
appropriately set up in the RDA, an error
will occur. Sets bit A of RDA Error ID
(MW3**81) if error state exists.
axisinerr
AB000028
The axis number
entered on the
input is not an
acceptable value
The function 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.
RDA_Error
AB000026
The module or axis
number in the RDA
is not acceptable
RDA module number MW3**83 refers to
the address of Module on the rack, and
can be from 1 to 16. The axis number
MW3**84 refers to the axis location on the
module and can be from 1-16. This
typically would occur if an RDAINIT
function block is not used for that axis.
Servo_Alarm/POWER_OFF
IB**2C0/IB**2C4
Servo Alarm
Servo amplifier fault occurred or main
power lost. Sets RDA Error ID (MW3**81)
bit 6 on if no motor power, and bit 7 if
there is a servo alarm.
This table outlines the data in the forty-five registers used by the function block. There
is not usually any need for the user to access any of these bits directly.
