BE4
(flashing )
Brake Answer 1
Brake Answer-Back , Brake not Released. At
Start, Brake Answer-back is not input within
predetermined time (C8-04) after electric brake
release command is output–Electric brake not
released.
1. Check brake answer back circuit.
2. Increase the value of C8-04.
3. Check terminal status (U1-10).
BE5
(flashing)
Brake Answer 2
Brake Answer-Back At Stop. At Stop, Brake
Answer-back signal is not removed within
predetermined time (C8-11) after electric brake
release command is removed–Electric brake not
closed.
1. Check brake answer back circuitries
2. Increase the value of C8-11 time.
BE6
(flashing)
Brake Stop Alarm
Brake Proving Alarm. The BE6 alarm
indicates that the drive has commanded the
brake to set but it has detected more than the
expected encoder feedback. A BE6 alarm will
occur if the number of pulses received during
the BE6 detection time (C8-12) is greater than
the expected number of pulses (C8-13).
1. Please reference troubleshooting encoder
related faults on page 6-15.
BE7
Brake Welded
Brake Answer-Back Major Fault. At Power
Up, Brake Answer-Back is on - Electric brake
not closed.
1. Check if brake is closed.
2. Check brake answer back circuitry.
BUS
Opton Com Err
Option Card Communication Error.
Communication to the option card was lost.
1. Check all connections.
CALL
(flashing)
SI-F/G Com Call
Serial Communication Transmission Error.
Control data is not received correctly after
power supply is turned ON for 2 sec.
1. Check serial device connections.
2. Ensure drive is properly programmed for
serial communication.
Can’t Run
Drive not ready
User is giving a run command while a FWD
or REV is present at Power Up. 1. Check input terminals.
2. Check H1-01 to H1-06 programming.
CE
Memobus Com Err
Communication Error. Serial communications
disruption.
1. Check serial connections (6 CN).
2. Check H5-01 through H5-05 for proper
programming.
CPF00
Com-Err (OP&INV)
Control Circuit Fault 1— Keypad
Transmission.
Because of external noise, excessive vibration
or shock, or component failure (including RAM
and PROM), one or both of the following
occurs:
• Transmission between the inverter and
keypad cannot be established 5 sec after
power-up.
• External RAM of CPU is defective.
1. Check the keypad connection.
2. Replace keypad.
3. Replace Control board.
CPF01
Com-Err (OP&INV)
Control Circuit Fault 2—Keypad
Transmission.
After initial power-up,
communication between the inverter and
keypad was interrupted for more than 2
seconds.
1. Check keypad connection.
2. Cycle Power
3. Replace keypad
4. Replace Control board.
CPF02
BB Circuit Err
Base Block Circuit Fault. Base block circuit
fault at power-up.
1. Cycle power.
2. Ensure that the control board terminals are
shielded from electrical noise.
3. Replace Control board.
CPF03
EEPROM Err
EEPROM Fault. Invalid data found in the
EEPROM.
1. Cycle power.
2. Ensure that the control board terminals are
shielded from electrical noise.
3. Replace Control board.
