64 Anti-slip protection
When the elevator not running in overhaul state, if
the elevator continuous running beyond the F9-02 set
time (maximum 45 seconds) and the leveling switch
not act. system will regard this as detect the rope slip
fault, so stop the car all running
Standard
Settings
65
Trigger point
detection
protection of trigger
if system detect the contactor on abnormal state when
the elevator in running or stopping state, the system
will automatically protect
Standard
Settings
66
Motor over-current
protection
When detecting the motor current value is greater
than the maximum allowable, the system automatic
protection
Standard
Settings
67
Power source over-
voltage protection
When Detecting the power supply voltage is greater
than the maximum allowable value, the system
automatic protection
Standard
Settings
68
Motor overload
protection
When detecting the motor is overload
,the system automatic protection
Standard
Settings
69
Encoder fault
protection
System only use a high-speed encoder for closed
loop vector control, if the encoder failure, the system
stop automatically to avoid the runaway failure which
caused by the encoder failure not available.
Standard
Settings
70
shaft auto-tuning
failure judgment
Without right shaft data, the elevator will not be able to
running. so we set the self-learning fault diagnostic if
the shaft self-learning does not properly completed
Standard
Settings
71
Drive module
overheating
protection
When detecting the drive module overheating, the
system automatic protection
Standard
Settings
72
Door switch fault
protection
When detecting the elevator not yet close the door
effective after the elevator open and close the door
beyond the number set, system stop close and open
the door switch and output the fault.
Standard
Settings
73
Protection of door-
lock disconnect
when running
when the door-lock disconnected during the elevator
is running, the system automatic protection
Standard
Settings
74
Limit switch
protection
If the Up (down) limit switch action, the elevator ban
on run to up(down),but to run to the opposite direction
Standard
Settings
75
Over-speed
protection
Assurance the speed of car in the range of security
speed to ensure the passengers and cargo security.
Standard
Settings
76
leveling switch fault
protection
When the elevator in the automatic running mode, it
identify leveling signal loss and adhesion status.
Standard
Settings
77
CPU fault
protection
System has three CPUs to judge state each other, if
there is abnormal, the system block all output.
Standard
Settings
78
Output contactor
abnormal detection
By detecting the output current situation to determine
whether the output contactor is abnormal before the
brake open.
Standard
Settings
79
Protection against
false door locking
Elevator in the automatic running mode identify
whether the door-lock is anomalies every time open
the door in place
