6.3 SEW‑EURODRIVE electronics service
6.3.1 Sending a device in for repair
Please contact the SEW‑EURODRIVE electronics service if a fault cannot be rec-
tified
(→ "Customer and spare parts service").
When you contact the SEW‑EURODRIVE electronics service, always quote the digits
on the status label so that our service personnel can assist you more effectively.
Provide the following information when sending the device in for repair:
• Serial number (→ nameplate)
• Type designation
• Standard version or application version
• Digits on the status label
• Short description of application (drive application, control via terminals or serial)
• Connected motor (motor type, motor voltage,
W
or
W
connection)
• Nature of the fault
• Accompanying circumstances
• Your own presumptions as to what has happened
• Any unusual events preceding the problem, etc.
6.4 Extended storage
If the device is stored for a long time, connect it to the power supply for at least
5 minutes every 2 years. Otherwise, the device's service life may be reduced.
Procedure when maintenance has been neglected:
Electrolytic capacitors are used in the inverters. They are subject to aging effects
when de-energized. This effect can damage the capacitors if the device is connected
using the rated voltage after a longer period of storage.
If you have not performed maintenance regularly, SEW-EURODRIVE recommends
that you increase the line voltage slowly up to the maximum voltage. This can be
done, for example, by using a variable transformer for which the output voltage has
been set according to the following overview.
The following stages are recommended:
