(1) Determine which power supply your encoder requires and connect to only the specified supply. Do not make connections to both.
(2) Not applicable unless motor has integrated thermal protection. Common (TS-) signal for thermal switch is tied to MF-6 (ECOM) in Bulletin 2090 cables.
ATTENTION: To avoid damage to components, determine which power
supply your encoder requires and connect to either the 5V or 9V supply, but
not both.
IMPORTANT Combined motor-power cable length for all axes on the same DC bus must
not exceed 240 m (787 ft) with 460V systems. Drive-to-motor power cables
must not exceed 90 m (295.5 ft).
System performance was tested at these cable length specifications. These
limitations also apply when meeting CE requirements.
