Motor chokes 3YLNxx
To use with motor cables longer than 25m up to 50m max. to reduce velocity ripple and to
protect the output power stage of the amplifier. The terminals BR are used to connect the
motor holding brake. Beside the terminal are block two shield connection terminals for
safe connection of the cables's shielding braid.
Mount the choke nearby the servo amplifier. The cable length between amplifier
and choke must never exceed 2m. Connection see page 42 .
The increased absorption reduces the permissible rotative frequency and limits thereby
the permitted motor speed:
— with 6 poles motors to n
— with 8 poles motors
— with 10 poles motors n
The increased leakage current at rising cable length leads to the reduction of usable
amplifier output current of about 1A. Use only motors with more than 2A rated current, to
get a good regulation quality.
