5.5.1 Digital inputs
The CMMB motor controller provides 7 digital inputs. The functions of these digital inputs can be configured.
Functions can be set via factory defaults or application default settings after processing the Easy setup menu
( see chapter 4). The functions of the digital inputs can also be freely configured.
Figure 5-9: Digital Input
Function: Click
to select DIN function setting, click
to delete the DIN function setting.
Real: Shows the real digital input hardware status.
1
means “active”, logic status of the digital input is 1.
0
means “inactive”, logic status of the digital input is 0.
Simulate: Simulates the digital input active hardware signal.
1
means the digital input is simulated as “active”, logic status 1.
0
means no impact on the digital input logic status.
Polarity: Inverts the logic status of the digital input.
1
means Internal is set to 1 by “active” signal.
0
means Internal is set to 1 by “inactive” signal.
Internal: This is the result of Simulate, Real and Polarity via the logic formula:
Internal=(Real OR Simulate) XOR (NOT Polarity)
1
means “active”, logic status of the selected function is 1.
0
means “inactive”, logic status of the selected function is 0.
Information
More than one digital input function can be selected for a given digital input. If not
contradictory in any way, the selected digital input functions are handled simultaneously.
Several digital input functions modify controller-internal control variables. Please
familiarise yourself with the information in chapter 6.1, especially regarding Controlword
and Operation_Mode, before modifying the configuration of any related digital input
function.
