10.2.4 Motor chokes 3YLN
To use with motor cables longer than 25 m up to 50 m 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 2 m. Connection see page 41 .
The increased absorption reduces the permissible rotative frequency and limits thereby
the permitted motor speed:
— with 6 poles motors to n
max
= 3000 rpm
— with 8 poles motors n
max
= 2250 rpm
— with 10 poles motors n
max
= 1800 rpm
The increased leakage current at rising cable length leads to the reduction of usable
amplifier output current of about 1 A. Use only motors with more than 2 A rated current, to
get a good regulation quality.
