b) Variable machine mains supply connection:
Mains connection with industry connector according to EN 60309
and a minimum wire cross section of the protective conductor of
2.5 mm² (AWG 13) as part of a multi-conductor supply cable. Use an
adequate pull relief.
• Check the mechanics of the servo drive. If the housing is damaged
e.g. by transport, don’t use it. Don’t touch electronic components in
the drive.
• Compare the rated voltage and current of the servomotor to the data
of the servo drive. Do the wiring according to the Connection diagram,
page 25.
• Make sure, that the mains input voltage, under any condition, not
exceeds the maximum rating of the servo drive. Note also Possibilities
of mains supply.
• Define the external fusing of the mains input, 24 V auxiliary supply
and holding brake supply according to External fusing, page 32.
• Route the motor and control cables separately (distance about
100 mm). This improves the noise level of the control signals because
of the high radiation of the motor cables. Use only screened motor
and feedback cable with shield connections on both ends.
• The prescribed mounting position is vertical as shown on page 29.
• The airflow in the switchgear cabinet has to be in a way, that the servo
drives has enough cool and filtered air. See Ambient conditions page
19.
• Any modification of the servo drive will invalidate the warranty, except
setting the software functions by parameter.
• At start-up of the servo drive, check the setting of the peak current of
the servo drive. Especially small motors are damaged very quickly, if
the setting of the servo drive is too high (e.g. a 1 A – motor and the
6 A-unit, not reduced to 1 A!)
• In no-load condition, the intermediate circuit voltage can, over a period
of time, reach a value of up to 740 V. This causes no damage to the
module.
• Shelf life:
< 1 year: no limitations
≥ 1 year: The intermediate circuit capacitors of the servo drive system
must be reformed before the initial start up. In addition all electrical
connections must be removed and the supply module supplied with
230 V for 30 minutes, single phase at terminals L1 and L2.
