44 Rockwell Automation Publication 1560F-UM001A-EN-P - June 2019
Chapter 1 Product Overview
Bulletin 1560F • Standard Control
The Bulletin 1560F is intended for addition to an existing motor controller,
which provides circuit isolation, motor switching, and overload and overcurrent
protection. When wired as shown in Figure 26
, the controller operates as follows:
When a start is initiated in the existing motor controller and the contactor (or
breaker) closes, a contact must be supplied to tell the 1560F to start also. Start
and Stop are the same as Bulletin 1562F • Standard Control
on page 42.
The “Fault” contact on the SMC-50 module should be wired into the existing
controller to trip the main contactor (or breaker) in the event of a fault condition
sensed by the SMC-50 module.
If possible, it is better to have the SMC-50 module control the main contactor
directly. In this case, the control circuit would look like, and function like, the
descriptions above for the Bulletin 1562F.
Bulletin 1560F • Programming Interface Control
The control scheme shown in Figure 27 allows the SMC-50 to be controlled
using Programming Interface Control. See SMC-50 Control Module—Bit
Identification on page 140 for Logic Command Word bits assignment. This
interface includes provisions for a “Local” mode of control as well.
With the Local-Off-Remote selector switch in the “Remote” position, Start and
Stop are the same as Bulletin 1562F • Programming Interface Control
on
page 43. A stop command can be generated via this interface or by opening “CR”,
depending on the control mode.
If possible, it is better to have the SMC-50 module control the main contactor
directly. In this case, the control circuit would look like, and function like, the
descriptions above for the Bulletin 1562F.
