Err38
Encoder signal
abnormal
Subcode 101: The
pulses in F4-03 does
not change within the
time threshold in of
F1-13.
• Check whether the encoder is used correctly.
• Check whether the brake works properly.

Subcode 102: F4-
03 increases in down
direction.
• Check whether parameter setting and wiring
of the encoder are correct.
• Check whether system grounding and signal
grounding are reliable.
• Check whether the motor phase sequence is
correct.
Subcode 103: F4-
03 decreases in up
direction.
Subcode 104: The
SVC is used in
distance control
mode.
Set F0-00 (Control mode) to 1 (Feedback vector
control) in distance control mode.
Subcode 105: The up
limit switch acts when
the elevator runs in
down direction.
Check whether wiring of the up and down limit
switches are normal.
Subcode 106: The
down limit switch acts
when the elevator
runs in in up direction.
Subcode 107: The up
slow-down switch acts
in down direction, and
the down slow-down

direction.
Check whether wiring of the up/down slow-
down switch is correct.
Err39
Motor overheat
Subcode 101: The
motor overheat relay
input remains valid for
a certain time.
• Check whether the parameter setting (NO,
NC) is correct.
• Check whether the thermal protection relay

• Check whether the motor is used properly
and whether it is damaged.
• Improve cooling conditions of the motor.

Safety circuit
disconnected
Subcode 101: The
safety circuit signal
becomes off.
• Check the safety circuit switches and their
states.
• Check whether the external power supply is
normal.
• Check whether the safety circuit contactor
acts properly.
• Conrm the signal feature (NO, NC) of
the feedback contact of the safety circuit
contactor.
