Note These connections are not necessary for normal operation of the drive.
Following paragraphs are only valid when the control card is used on frames B, C & D:-
Connection can be made from the X01 terminal on the 890CS Common Bus Supply unit. This 24V DC
control supply allows for configuration and commissioning of the system without the DC supply being
present. The drive will operate with this supply but will not turn a motor.
Connection is not required when the DC supply is present, but the connection can be safely left connected.
You can connect an 890CS unit to a maximum of three 890CD units when daisy-chaining 24V using these
terminals (8A maximum). If you have more than three 890CDs, use a 24V rail and wire as shown in the
Wiring Diagram on page 4-12.
