Faults and Alarms .
26 | CTW900
Fault/Alarm Description Possible Causes
A129:
Anybus Offline ■ Signals that the Anybus-CC communication was interrupted. ■ PLC master went to idle status (Idle or
Prog.).
■ Programming error (number of I/O words
programmed on the slave differs from the
setting on the master).
■ Loss of communication with the master
(broken cable, connector disconnected,
etc.).
A130:
Anybus Access Error ■ Signals error of access to the Anybus-CC communication
module.
■ Anybus-CC module defective, not
recognized or incorrectly installed.
■ Conflict with WEG option board.
F148:
Change Bridge Fault ■ Occurs when the measurement of armature current doesn’t
become discontinuous during the Exchange Bridge routine.
■ Problem in measuring circuit of the
armature current.
■ Defective t hyristor(s).
F149:
Incompatible PLD
Firmware ■ The firmware recorded on the PLD of the control board is not
compatible with the firmware of the CTW900.
■ PLD not recorded.
■ PLD with firmware of another product.
F150:
Motor Overspeed ■ Actuates when the motor speed exceeds the value of P0132
(in percentage of P0134) for over 2 seconds.
( ) = (100% + 0132) × 0134
■ P0132 set too low.
F151:
Flash Memory Module
Fault ■ Actuates when a fault is present in the FLASH Memory Module
(MMF-03).
■ FLASH memory module defective.
■ FLASH Memory Module not well fitted.
F154:
Speed Feedback Fault ■ Actuates when the difference between the DC Tacho or
Encoder speed and the EMF exceeds the value of P0354 (in
percentage of P0402).
( ) = 0354
× 0402
Note: The monitoring of this fault is only started when the EMF
exceeds the level defined in P0353.
It is also possible to disable the protection setting P0352=1.
■ Disconnection of the tacho or encoder
cable.
■ Setting of P0405 incompatible with the
encoder used.
■ Setting of P0406 incompatible with the
tacho used or incorrect wiring of the tacho
cables to connector XC4.
■ Armature circuit is open.
F156:
Under temperature ■ Signals when the temperature measured on the heatsink is
below -5°C.
■ Temperature sensor cable disconnected
(XC8).
■
Ambient temperature below -5°C.
F158:
Thermostat of Armature
Open ■ Actuates when one of the thermostats assembled in the
armature bridge is open.
Note: This fault will only be active in converters of Frame Size D,
which are equipped with thermostats in the armature bridge.
■ High temperature at the armature bridge
(over 88°C).
■ Cable of the thermostat disconnected
(XC6).
F159:
Armature Fuse Fault ■ Actuates when one of the armature fuses is open.
Note: This fault will only be active in converters of Frame Size D,
which are equipped with internal fuses.
■ Some armature fuse break sensors
open.
■
Cable of the fuse break sensor
disconnected (XC7).
A163:
Broken wire in AI1 ■ Signals that the reference in current (4-20mA or 20-4mA) of
the analog input 1 (AI1) is out of the correct range.
■ Cable of AI1 broken.
■ Poor contact in the signal connection on
the control board terminals (connector XC1
of board CC900).
A164:
Broken wire in AI2 ■ Signals that the reference in current (4-20mA or 20-4mA) of
the analog input 2 (AI2) is out of the correct range.
■ Cable of AI2 broken.
■ Poor contact in the signal connection on
the control board terminals (connector XC1
of board CC900).
A165:
Broken wire in AI3 ■ Signals that the reference in current (4-20mA or 20-4mA) of
the analog input 3 (AI3) is out of the correct range.
■ Cable of AI3 broken.
■ Poor contact in the signal connection on
the control board terminals (connector XC1
of board CC900).
A166:
Broken wire in AI4 ■ Signals that the reference in current (4-20mA or 20-4mA) of
the analog input 4 (AI4) is out of the correct range.
■ Cable of AI4 broken.
■ Poor contact in the signal connection on
the control board terminals (connector XC1
of board CC900).
A181:
Clock with Invalid Value ■ Signals that the keypad (HMI) clock has an invalid date or time. ■ Necessary to set the date and time in
P0194 to P0199.
■
Keypad (HMI) battery low, defective or
not installed.
F229:
Anybus Offline ■ Actuates when an interruption in the Anybus-CC
communication occurs.
■ PLC master went to idle status (Idle or
Prog.).
■ Programming error (number of I/O words
programmed on the slave differs from the
setting on the master).
■ Loss of communication with the master
(broken cable, connector disconnected,
etc.).
