Smitec 3010FA - Auxiliary Power

Servodrives / inverters series COSMOS 301X Installation, use and maintenance manual - EN
5.7.6 24V auxiliary power
Some versions of the servo-drive/inverter require 24VDC auxiliary power to operate the control logic, the I/Os
and other peripherals (such as encoder). If auxiliary power is absent, the servo-drive will not operate, even
though it is powered by 230VAC.
CAUTION
For safety reasons, the auxiliary power must be supplied by a PELV power supply with its
earth terminal connected to earth (preferably only at one point, to prevent earth loops).
ATTENTION
Pour des raisons de sécurité, cette alimentation doit être fournie par une alimentation de
type PELV, la borne de terre étant reliée à la terre (de préférence uniquement en un point
pour éviter les boucles de terre).
The auxiliary voltage must be stable and within the limits of the servo-drive (see specific paragraph). If this
voltage is outside the prescribed limits, the servo-drive may be damaged.
Check the polarity of the auxiliary power before connecting the servo-drive; otherwise it may
be damaged.
