5.8.7 Slave parameters
When configuring the Profibus, it is possible to set some parameters for the slave. These
parameters are setup during start-up and cannot be changed during operation.
XX Input level
Using these parameters, the input level of the inputs IN1, IN2, IN3, IN4, NL and PL can
be selected.
Possible values:
Active high: The input will be active, when a signal is applied.
Active low: The input will be active, when no signal is applied.
End-limit action
Using this parameter, the action taken when an end limit is activated can be selected.
Possible values:
Velocity = 0: When the end-limit is activated, the velocity will be set to 0 and the
motor will decelerate and stop. If the motor should run again, the user
must manually set a new velocity.
Passive mode: When the end-limit is activated, the actual mode will be changed to
passive. In passive mode the motor is short-circuited and can be rotat
-
ed.
In firmware version 1.4 or higher, the “end-limit action’ is also active if the Profibus is go-
ing off-line but it needs to be online before it goes off line before the feature is enabled.
Input debounce
Using this parameter, an input filter can be activated.
Possible values:
Disabled No filtering will be done on the inputs.
Enabled The inputs are filtered, resulting in better noise immunity but slower
response. When the filter is enabled, there will be a delay at the input
of about 5ms.
Input x action
Using these parameters, up to 3 actions can be assigned to each input.
These actions are used when the custom input mode is selected. See Input modes, page
275.
The action is defined by a FlexMac command. See FastMac commands, page 277.
Possible values are 0-127, where 0 represents no action.
