9.6 Axis Unit Abnormal codes
9.6.1 AXis Unit Control abnormals
Refer to Section 9.4.16 Axis Unit Lockout. (Display is Blank) NONE
Refer to Section 9.4.4 Preset Data Abnormal. PRESET DATA
ABNORMAL A9
Refer to Section 9.6.2 Axis Unit Servo Drive Abnormals. When a
Servo Abnormal occurs, the System may generate a "D" code
Abnormal. If the Reset input is pulsed, the cause of the Abnormal
("D" code) will clear, leaving the "A8" code as a general Servo
Alarm indicator. Refer to Section 9.4.14 Servo I/F Power Supply
Abnormal and Section 9.4.15 Servo Type Abnormal. SERVO AMPLIFIER
ABNORMAL A8
Not Used. A7
This function is currently disabled. If this Abnormal occurs, it may
indicate a problem in the Axis Unit. Replace the Axis Unit. MOTOR ABNORMAL A6
Refer to Section 9.4.5 for an Encoder Angle Pulse Abnormals.
This Abnormal code generally indicates a problem in the Axis Unit

ABNORMAL A5
An abnormal condition has occurred in the Axis Unit memory or in
associated ribbon cables. This type of Abnormal may cause the
Main Unit to display any of the Axis Unit Abnormal error messages.

Refer to Section 9.4.3 for an Offset Check Abnormal. OFFSET CHECK
ABNORMAL A2
Review the abnormal display on the system CRT to determine
whether the Abnormal condition is from a "Zero Check Abnormal",
"Cal Check Abnormal", or "Full Scale Torque Over Abnormal".
Refer to Section 9.4.1 for a Zero Check Abnormal.
Refer to Section 9.4.2 for a Cal Check Abnormal.
