(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: To avoid damage to components, determine which power supply
your encoder requires and connect encoder power to either the 5V or 9V supply,
but not both.
IMPORTANT Drive-to-motor power and feedback cable length must not exceed 50 m
(164 ft) or 30 m (98 ft) depending on feedback type. System performance was
tested at these specifications and also applies when meeting CE requirements.
