➢ H32: 817/818 SWITCH ACTIVATED IN
WRONG DIRECTION
While the car is moving in the up direction, if 817 signal
turns to OFF position from ON position, or while the car
is moving in the down direction, if 818 signal turns to
OFF position from ON position, this error is raised.
If this error is triggered during the up direction move, 817
needs to be checked. If this error is triggered during the
down direction move, 818 needs to be checked.
There may be cut or short circuit in 817,818 signals.
There may be problem with 817,818 connection cables.
The motor direction needs to be checked by giving move
in the up and down in the inspection mode.
➢ H33: SHAFT ENCODER DIRECTION
REVERSE.
Shaft encoder connections need to be checked.
➢ H34: NO ENCODER SIGNAL.
Encoder connections need to be checked.
➢ H35: SPEED GOVERNOR MONITORING
ERROR
While the position of overspeed governor is monitored
over the normally closed contact on ARCUBE, if an
unexpected signal position is detected, this error is raised.
When “2.10: OSG COIL CONTROL” parameter is
selected as “ENABLED”, “SGC” monitor input needs to
be checked. While the car is moving, there shouldn’t be
signal over here. While it is in standstill position, there
should be 24V.
➢ H36: IPM ERROR, TRANSISTOR SHORT
CIRCUIT
There may be a short circuit in the power unit inside
motor driver. When the car stops suddenly, this error may
be given. The device may be a problem with the device.
➢ H37: IPM ERROR, DRIVE SUPPLY UNDER
VOLTAGE
There may be a problem with the IPM supply circuit
inside the motor driver.
➢ H38: IPM ERROR, IPM OVER HEATED
When the temperature of power unit inside the motor
driver is increased too much, this error is raised. Be sure
that the device is selected correctly according to the
motor.
➢ H39: MOTOR ENCODER DIRECTION
WRONG
When the encoder connections are done reversely, this
error is raised. The encoder direction from the menu
needs to be changed.
“For the synchronous machines, when the encoder
direction is changed, a new autotune process needs to be
performed.”
➢ H40: FIRMWARE OF MDC IS INVALID
MDC firmware needs to be updated.
➢ H41: NO COMMUNICATION WITH FX-
CUBE. CHECK CONNECTION AND
FIRMWARE
When the device couldn’t communication with the car
top Fx-Cube board, this error is raised. The firmware of
FX-Cube needs to be updated.
During the installation, if the inspection box is not
connected, operation mode parameter should be selected
correctly.
➢ H42: NO COMMUNICATION WITH ENCA
ENCODER BOARD
When the device couldn’t communicate with ENCA
board, this error is raised.
The cable between ENCA and ARCUBE needs to be
checked.
The leds on ENCA board should be changing their
position for a correct working operation.
There may be a problem with the selected encoder type
from the menu, or with the encoder supply.
➢ H43: SERIAL CONNECTION ERROR WITH
ABSOLUTE ENCODER
The connection between encoder and encoder board need
to be checked. Selected encoder type from the menu
needs to be checked.
➢ H44: SERIAL CONNECTION ERROR WITH
MDC
When the communication cable between MDC and LCB
doesn’t exist, or the cable is disconnected, this error is
raised. The communication cable should be checked.
➢ H45: L1, L2, L3 PHASE ORDER FAILURE
When “2.32: PHASE ORDER CONTROL” parameter
from the menu is selected as “ENABLED”, if there is a
