CB1.3 |
enLatch FallEdge |
1bin |
External latch event is enabled (for latch inputs with falling edge, the terminal saves the current position) |
|
CB1.2 |
enLatch RiseEdge |
1bin |
External latch event is enabled (for latch inputs with rising edge, the terminal saves the current position) |
|
CB1.1 |
SetCounter |
1bin |
The counter is set to the value specified by register R5 if a rising edge occurs at CB1.1. |
|
CB1.0 |
Reduced Torque |
1bin |
Reduced torque (coil current) is active (specified via R41) |
Status byte 1 (for process data mode)
The status byte 1 (SB1) is located in the input image, and is transmitted from terminal to the controller.
