6 Mains chokes
You must read the instructions manuals for the servo amplifier and servo motor you are using
in your application. Observe the safety instructions given there.
6.1 General
A 3L mains choke must be used on S640/670 servo amplifiers in order to reduce mains har-
monics.
In special cases, if mains voltage is more than 3% asymmetrical, then the S748/772 must be
used with a mains choke. In unfavorable combination of mains impedance and DC bus capa-
citance the unloaded DC bus may reach voltage up to 800V without choke. For EMC reasons
the chokes should be mounted isolated to the cabinet. Single conductors can be used for wir-
ing, shielded cables are not required. More information see WIKI "Mains Choke".
Purpose of mains choke:
l Prevents impermissible loading of semiconductors in the event of rapid current rise during
commutation.
l Prevents voltage dips in the mains voltage caused by commutation.
l Reduces current ripple in the DC link, thereby increasing the service life of the DC link
capacitors.
6.2 Important notes
DANGER
Power terminals are capable of conducting hazardous voltage up to
10minutes after the mains voltage has been disconnected. Risk of elec-
tric shock. Before starting work on power terminals, check that the phase-
to-earth and phase-to-phase voltages have de-energised.
Due to the high earth leakage currents induced by the system, you should observe the
requirements of EN 61800-5-1 (e.g. fixed installation, ≥ 10 mm² or double protective earth)
when carrying out mounting and installation work. You must read the instructions manual for
the servo amplifier/servo motor you are using in your application and observe the safety
instructions they contain before commencing mounting/installation work.
Mounting: 50mm free space required above and below the device.
