IMPULSE®•G+ & VG+ Series 4 Instruction Manual – February 2017
6-5
BE2
No Current
Torque Proving Fault.
Before the
brake is released, the drives current/
torque did not reach Initial Brake
Release Torque level (C08-16) within
the IFB OK timer (C08-02).
1. Ensure the motor has been Auto-
tuned successfully.
2. Confirm that the holding brake is
closed.
3. If a power limit switch is used,
ensure that the switch is closed.
4. Decrease the value of C08-02 to
no less than 0.5 seconds.
5. Decrease the value of C04-02 to
no less than 5.
6. Decrease the value of C08-16 to
no less than 50.

BE3
Brake Release NG
Brake Release Fault.
The BE3 fault
indicates that the drive has released
the brake and commanded the drive
to run, but it has not detected the
expected encoder feedback. A BE3
fault will occur if the pulses received
during the BE3 detection time (C08-
06) are less than the expected
number of pulses (C08-07).
1. Please reference encoder related
faults on page 6-16.

Brake Answer 1
Brake Answer-Back, Brake not
Released.
At Start, Brake Answer-
back is not input within
predetermined time (C08-04) after
electric brake release command is
output–Electric brake not released.
1. Check brake answer back circuit.
2. Increase the value of C08-04.
3. Check terminal status (U01-10).

BE4-2
Brake 2 Answer 1
Brake 2 Answer-Back Brake not
Released.
Brake 2 Answer-Back
does not release during Brake
Release state.
1. Check brake answer back circuit.
2. Increase the value of C08-04.
3. Check terminal status (U01-10).

Brake Answer 2
Brake Answer-Back At Stop.
At
Stop, Brake Answer-back signal is
not removed within predetermined
time (C08-11) after electric brake
release command is removed–
Electric brake not closed.
See the Fault Latch Table for on page
5-120 for Fault Latching Options.
1. Check brake answer back
circuitries
2. Increase the value of C08-11
time.

BE5-2
Brake 2 Answer 2
Brake 2 Answer-Back at Stop.
Brake 2 Answer-Back does not close
during Brake Set time.
1. Check brake answer back
circuitries
2. Increase the value of C08-11
time.

BE6
(flashing)
Brake Stop
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 (C08-12) is greater than the
expected number of pulses (C08-13).
See the Fault Latch Table for on page
5-120 for Fault Latching Options.
1. Check the brake.
2. Please reference troubleshooting
encoder related faults on page 6-
16.
