Programming Guide
high impulse" signals can trigger the test timer and test information is included in the LCP and status word, as emergency mode
output "not operating as expected" is activated.
Parameter 24-43 Emergency Mode Signal Operation
Table 1052: Parameter 24-43 Emergency Mode Signal Operation
24-43 Emergency Mode Signal Operation
Default value: [0] Standard, active-high
Conversion index: -
Ensure that the correct input selections and connections are in place as it is not possible to operation the LCP while emergency
mode is activated.
If signal handling is set to inverse, a low [196] EM active and a low [197] EM was active indicate that the drive is off or power cy-
cling, which can be used to activate a redundant system.
Select how emergency mode input and output signals are handled. Before changing this parameter, disable parameter 24-00 Emer-
gency Mode Function.
Op- Name Description
tion
[0]* Standard, ac- Normal high input and output signals operate the emergency mode function as long as they are active
tive-high (high).
[1] Inverse, ac- This option adds safety rules to ensure that emergency mode still operates if a signal is lost.
tive-low
[2] Impulse, set- This option activates and stops the emergency mode operation on high signal impulse. Operation
reset mode is defined and activated by selected input signals and is frozen 2 s after the 1
Reset signal has the highest priority and is required to stop operation or switch to a new operation con-
figuration. A valid signal impulse has to be active for minimum 2 s.
LCP copy and software download only accept parameter changes if parameter 24-00 Emergency Mode
is set to [0] Disabled.
5.22.4 24-9* Multi-Motor Funct.
Parameter 24-90 Missing Motor Function
Table 1053: Parameter 24-90 Missing Motor Function
24-90 Missing Motor Function
Default value: [0] Off
Conversion index: -
Select the action to be taken if the motor current is below the limit calculated as a function of the output frequency. The function is
used for detecting, for example, a missing motor in multi-motor applications.
