12.17 SSM via Input (Switch Mode = 15)
With parameter setting “Switch Mode” = 15, an SSM function is assigned to the output.
The function is triggered by underspeed, independent of the direction of rotation. The
function requires an enable input signal which must be assigned by parameter „Matrix
“
A lock function can be set separately, which can be acknowledged by a further input.
Acknowledgement is only possible with frequencies higher than underspeed, or with the
enable signal deactivated.
Relevant Parameters Remark
„Matrix “
use only inputs, but no feedback outputs
„MIA-Delay “
= 0 (can also be set according to need)
„MAI-Delay “
= 0 (can also be set according to need)
„Lock Output“ for lock function use only range 0-31
„Output Mode“ homogenous or inverse (affects the Safety Integrity Level SIL/PL)
„Delay “
shutter release delay
„Presel. . “
switching point
„Input Mode “
configuration of the control inputs (affects the safety level SIL/PL)
„ IN Function“
function of the control input
„ IN Config“
switching behaviour (single-channel, two-channel, inverse, homogeneous,
dynamic, static)
„GPI Err Time“ max. permissible delay time during illegal conditions
Relevant input functions Remark
Enable, e.g. Parameter „IN1 Function“ = 21 activates the function
Clear lock function, e.g. parameter „IN2 Function“ = 1 … 6 Only when lock function is active
