Diagnostics and troubleshooting
− Check the connection between VSD and motor
− If the fault occurs constantly, disconnect the motor
cable from the VSD and start the VSD without
having the motor cable connected. If the fault still
occurs, there is a defect inside the VSD, which
means that the VSD must be replaced. If the fault
does not occur without having the motor connected,
the motor cable or motor causes the fault. Connect
the motor cable (without motor) to the VSD, enabling
you to check the condition of the motor cable
− Check the motor data entered for quick
commissioning
− Make automatic motor identification (refer to section 6.6)
Only if the VSD, the motor and the motor cable have
been checked (no faults detected) and the motor
temperature is monitored by an additional temperature
sensor (e.g. PTC), can the fault be hidden on the VSD
via parameters P2100[0] = 23 and P2101[0] = 0
− This fault is caused by some other fault, which led to
shutdown and which must be rectified first. The error
code of the initial fault, which led to the restart, is
stored in parameter r0947, index 001
− Check the settings of function "Automatic restart"
using parameters P1210 - P1213
− Automatic motor identification must NEVER be
aborted by an OFF command
− Check to see if the motor data in P304 - P311 are
correct
− Check to see which type of motor connection is
required (star or delta)
− Check to see if the motor is correctly connected to
the VSD
− Check the condition of motor cable and motor
− A reset to the default values cancels all undesired
parameter settings and retrieves the default settings.
The VSD must be recommissioned
− Replace the VSD
Install V1.41 or higher
− Firmware version (r0018) must be 1.17 or higher
− A reset to the default values cancels all undesired
parameter settings and retrieves the default settings.
The VSD must be recommissioned
− Replace the VSD
Install V1.41 or higher
− Check the rigidity and proper fitting of the I/O board.
Is the component correctly plugged in and
connected?
− Check ASN of the I/O board. Is it an SED2 I/O board
(SED2-IOBD1)?
− A reset to the default values cancels all undesired
parameter settings and retrieves the default settings.
The VSD must be recommissioned
− When above points have been checked and
complied with, the I/O board must be replaced, or
the fault can be hidden on the VSD via parameters
P2100[0] = 54 and P2101[0] = 0
