Table 8.1 Table of HT-L linear table malfunctions (continuation)
Fault Possible cause Remedy
Upon restart, the
drive reports a fault
during commutation
Motor phases connected incorrectly Check rotational direction
Encoder counting direction incorrect Change the sin and cos pair of wires in the encoder
plug
Carriage is too close to the limit switch/
limit stop
Disconnect power supply to axis and move carriage
manually into the centre of the axis
Carriage blocked Check carriage manually for free movement
No symmetrical force ratios
Additional drive resistance
Change parameters in the drive amplifier
Axis overspeeds upon
restart
Commutation incorrect See fault during commutation
Check commutation parameters in the drive, activate
speed monitoring
EMC interference with the encoder
signal
Check the shielding of the connectors and cables
Axis overspeeds in
positioning mode
Programming error in the position
transfer, invalid acceleration ordered
Activate security settings in the drive amplifier, such
as speed monitoring, permissible position errors etc.
Rated power exceeded as duty cycle is
too long
Adapt load cycle to the rated power of the motor
Motor heats up too
much (measure
temperature)
Cooling insufficient Rectify cooling air supply or open cooling air pas-
sages, retrofit external fan if necessary
Carriage is difficult to move Check lubrication of the guidings, check for foreign
bodies in the traversing range
Ambient temperature too high Observe permissible temperature range
Load cycle has been modified Calculate load cycle and adapt accordingly
Drive amplifier motor commutation does
not function properly
Adapt commutation parameters of the drive amplifier
Operating noise from
the carriage
Relubrication required or bearing
damage
Lubrication or consultation with HIWIN GmbH
After homing, there is
an offset of 1 mm
The position of the cam switch is
exactly between two index pulses of the
MAGIC-PG
Shift of the cam switch by approx. 0.5 mm
The axis generates
cracking noises when
it is subject to control
EMC interference in the encoder signal Encoder cables must be used with separately shielded
sin and cos signal pairs
Commutation incorrect Optimise commutation parameters
The carriage jerks
while moving and
generates operat-
ing noise that is not
caused by the profile
rail
EMC interference in the encoder signal,
encoder cable plug connection defec-
tive, pin bent in plug
Place motor cable and/or encoder cable shield in full
contact with the earthing terminal of the amplifier,
check pin in plug
Wrong controller parameters Check controller parameters, check tuning
Position discrepan-
cies after several
hours of operation
Wrong settings for duty cycle
Overload
Heat transfers
Check operating range;
check if axis is operating within the specifications
