(1) Not applicable unless motor has integrated thermal protection.
(2) Determine which power supply your encoder requires and connect to only the specified supply. Do not make connections to both.
ATTENTION: The motor feedback will determine which encoder power
source is used. Be sure you use the correct power source for your encoder
to avoid equipment damage.
IMPORTANT
For the maximum length of the drive to motor power and feedback
cable, see Maximum Cable Length
on page 95. System performance
was tested at these specifications and also applies when meeting CE
and UK requirements.
