} Monitored start with falling edge
If a monitored start with falling edge is configured, the output switches on if the speed
does not reach the limit value and then a falling edge was detected at S34.
Switch delay
A delay time can be set for each output (see technical details). The outputs will not switch
until the set time has elapsed. It is possible to configure whether the delay time is to be ac-
tivated when switching on, switching off, or switching on and off.
Feedback loops
Feedback loops are used to monitor external contactors or relays. The corresponding feed-
back loop must be closed before starting.
Start-up delay
A start-up delay time can be configured, which prevents the evaluation of the encoder sig-
nals for the configured time period after the supply voltage is switched on.
Switching direction on semiconductor outputs
The semiconductor outputs can be operated in normally de-energised or normally ener-
gised mode.
Units
The values to be configured can be entered in various units. Depending on the axis type
(linear or rotational axis), various units can be selected for speed and distance (see chapter
entitled "Menu overview").
