8 Troubleshooting
Table 8.1: Fault table
Fault Possible cause Remedy
Motor does not start Supply lines disconnected Check connections, plug contacts may be
compressed, repair if necessary. The connectors
have seals, which means that a certain screw
connection resistance must be overcome.
Fuse has tripped via motor
protection Check motor protection for the right settings,
remedy defects if necessary.
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.
Forcer housing is too close to the
limit switch/limit stop Disconnect power supply to axis and move forcer
housing manually into the center of the axis.
Additional drive resistance e.g.
sealing lip, without parameter
adjustment 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.
Motor heats up too much
(measure temperature) Rated power exceeded as duty
cycle is too long Adapt load cycle to the rated power of the motor.
Cooling insufficient Rectify cooling air supply or open cooling air
passages, retrofit external fan if necessary.
Forcer housing is difficult to move Check lubrication of the guideways, 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 forcer Relubrication required otherwise
risk of bearing damage
Lubrication or consultation with HIWIN
The axis generates cracking
noises when it is subject to
control EMC interference in the encoder
signal Encoder cables must be used separately with
shielded sin and cos signal pairs.
Commutation incorrect Optimize commutation parameters.
The forcer jerks while moving
and generates operating noise
that is not caused by the profile
guideways
EMC interference in the encoder
signal, encoder cable plug
connection defective, 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
Position discrepancies after
several hours of operation Use mains filter to stabilize voltage
