Appendix C
1560F and 1562F Relay Control
If the loss of current loop transformer assembly is detected by SMC-50 control
module, then the terminal A2 will be maintained at high, and terminal A3 will be
adopted to initiate the stop. In this situation, when the stop button is pressed, the
CR relay opens the terminal A3 of 150-SM4 Digital I/O card inserted in SMC-
50 module, Terminal A3 will be always programmed to be Coast-to-stop, so that
when current loop transformer assembly doesn't work properly, the SMC-50 will
only do Coast-to-Stop.
If the motor has started, the unit is in the bypass mode, and a trip occurs within
the SMC-50 module or from an external protection relay, AUX2 will open the
line contactor immediately. “AUX1” will remain closed for the number of
programmed seconds to protect the power electronics from any voltage transients
due to opening the motor circuits. A trip due to an overload or fault condition
will result in a “coast” stop.
Bulletin 1562F • Programming Interface Control
The control scheme shown in
allows the SMC-50 to be controlled
using Programming Interface Control. (Refer to
for Logic Command Word bits assignment for DPI
control). This interface includes provisions for a “Local” mode of control as well.
With the Local-Off-Remote selector switch in the “Remote” position, terminal
A2 and A3 of the 150-SM4 DigitaL I/O card will be maintained high, and
terminal A1 will open which allows a start command to be executed via this
interface. The EStop button still works in remote mode. The “Aux #2” contact
closes, energizing “MC”, which closes the main contactor.
When the motor approaches rated speed, the SMC-50 module closes “Aux #1”
contact, energizing “BC”, which closes the bypass contactor.
A stop command can be generated via the programming interface to stop the
motor, depending on the stop mode.
If the motor has started, the unit is in the bypass mode, and a trip occurs within
the SMC-50 module or from an external protection relay, AUX2 will open the
line contactor immediately. “AUX1” will remain closed for the programmed
number of seconds to protect the power electronics from any voltage transients
due to opening the motor circuits. A trip due to an overload or fault condition
will result in a “coast” stop.
