12 Monitoring Functions
The monitoring functions are used to set the properties of digital outputs and relay output.
12.1 Overspeed (Switch Mode = 0)
With parameter setting “Switch Mode” = 0, the frequency is monitored for overspeed.
The function is always active and independent of the direction of rotation. The
switching point for overspeed is always at Frequency = Presel (no matter if with or
without hysteresis).
Relevant Parameters Remark
„Switch Mode “ = 0
„Pulse Time “
statically = 0 or pulse duration in x seconds
„Hysteresis “
hysteresis
„Lock Output“ lock function
„Output Mode“ homogenous or inverse output configuration (affects the Safety Integrity Level
SIL/PL)
„Presel. . “
switching point
„Delay “
shutter release delay
„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)
Relevant input functions Remark
Clear lock function, e.g. parameter „IN1 Function“ = 1 … 6 Only when lock function is active
Switchover switching points, e.g. parameter „IN2 Function“ = 13 Only when switchover is active
Example:
With Presel = 1000.0 Hz and Hysteresis = 10 %, frequencies |f|
≥
1000 Hz are detected
as overspeed. The overspeed output will be cleared with frequencies |f| < 900 Hz.
