Error
Code
Definition
Possible Solution
Er2
Door inter-lock faults: Door inter-lock circuit open
at elevator running
Check the work condition of door vane and door
interlock circuit. Roller should have enough space at
both side of the vane.
Er3
Driver faults
Check drive-error code. Determine the possible
cause of the fault and solve in corresponding
solution.
Er4
Elevator running in opposite direction with
command
1. Exchange phase “V” and “W” on motor
2. Exchange phase “A” and “B”, on encoder terminal
block or change in parameter setup.
Er5
Brake open fault: System does not receive brake
open feedback signal after output brake open
command:
1. No X6/X31 feedback after Y0output 0.5/2s.
2. X6/X31 enable when Y0 has no output.
1. Check the traction machine brake detection
switch and wiring;
2. If no feedback switch, should set feedback enable
to OFF
Er6
During elevator running, leveling zone input
signal X3, X4 is always on.
Check leveling zone signal circuit and induction
switch
Er7
Inverter pulse not enough at elevator running.
Check the wiring from encoder to controller.
Er9
KDY fault: Contactor KDY output not matching
feedback signal:
1. After Y1 output X5 no feedback in 0.4s.
2. X5 is enabled when Y1 has no output.
Check the contactor KDY coil and output/feedback
circuit wiring.
Er10
Safety circuit open, input X10 is invalid.
Check all safety circuits.
Er11
Leveling switch signal missing: Elevator is running
pass the floor, but there is not input at X3 /X4.
Check the leveling switches and its wiring.
Er12
Elevator pass top limit switch (X1 is invalid)
Check encoder, top limit switch including its
position / wiring.
Er13
Elevator pass bottom limit switch (X2 is invalid)
Check encoder, bottom limit switch including its
position / wiring.
Er14
Floor counter error from encoder deviation
accumulation: after this error, elevator will return
to bottom floor in inspection speed for
recalibration.
1. Check encoder wiring and related circuits;
2. Check the leveling switch and related circuits;
3. Possible reason: traction rope slip /door drive
shake at start.
Er17
No drive output after running command.
Check parameters in controller or contact supplier.
Er18
Floor number error: after this error, elevator will
return to bottom floor in inspection speed for
recalibration.
Check the encoder and its wiring.
Er19
The deceleration distance for target floor is not
enough, elevator did not perform hoistway
parameter learning after changing terminal
switch location.
1. Decrease “Least Speed” in user menu; make
elevator running curve steeper; reduce speed
adjusting distance;
2. Do hoistway parameter learning again.
Er20
When elevator reaches top/bottom floor and get
deceleration instruction, but elevator doesn’t
slow down; elevator did not perform hoistway
parameter learning after changing terminal
switch location.
1. Increase the proportion parameter of controller;
Check the braking resistor specification;
2. Make elevator running curve smoother;
3. Do hoistway parameter self-learning.
Er21
Single running time is over set time
1. Check related parameters in controller;
2. Check the traction rope for slip or car jam;
3. Check value of parameter “Over Time”.
Er22
Elevator has inspection signal input (X0 invalid) at
elevator normal running.
Check inspection switch and related circuits.
Er23
One of two leveling switch (X3, X4) is invalid at
elevator normal running.
Check leveling switches and wirings.
