Brake contactor
feedback
abnormal
Subcode 101: The output
of the brake contactor
is inconsistent with the
feedback.
◆
Check whether the brake contactor opens
and closes properly.
◆
Check that the signal feature (NO, NC) of the
feedback contact on the brake contactor is
set correctly.
◆
Check whether the feedback circuit of the
brake contactor is normal.
5A
Subcode 102: When both
feedback signals of the brake
contactor are enabled, their
states are inconsistent.
◆
Check the signal feature (NO, NC) of the
feedback contact on the brake contactor is
set correctly.
◆
b. Check whether the states of the multi-way
feedback contacts are consistent.
Subcode 103: The output
of the brake contactor is
inconsistent with the brake
travel switch 1 feedback.
◆
Check whether the signal feature (NO, NC)
of the brake travel switch 1/2 feedback is set
correctly.
◆
b. Check whether the circuit of the brake
travel switch 1/2 feedback is normal.
Subcode 106: The output
of the brake contactor is
inconsistent with the brake
travel switch 2 feedback.
Subcode 105: The brake
contactor feedback is valid
before the brake contactor
opens.
◆
Check whether the feedback contact of the
brake contactor mal-functions.
Subcode 104: When both
feedback signal of brake travel
switch 1 are enabled, their
states are inconsistent.
◆
Check whether the signal feature (NO, NC)
of the brake travel switch 1/2 feedback is set
correctly.
◆
b. Check whether the states of the multi-way
feedback contacts are consistent.
Subcode 107: When both
feedback signal of brake travel
switch 2 are enabled, their
states are inconsistent.
Subcode 108: The brake
contactor output is
inconsistent with the feedback
of brake travel switch 1 on the
IO expansion board.
◆
Check whether the signal feature (NO, NC) of
the brake travel switch 1/2 feedback on the
IO expansion board is set correctly.
◆
b. Check whether the circuit of the brake
travel switch 1/2 feedback is normal.
Subcode 109: The brake
contactor output is
inconsistent with the feedback
of brake travel switch 2 on the
IO expansion board.
