6.4.3 Setting the drive enable output
A drive enable output allows NextMove ES to enable the external drive amplifier to allow
motion, or disable it in the event of an error. Each axis can be configured with its own drive
enable output, or can share an output with other axes. If an output is shared, an error on any
of the axes sharing the output will cause all of them to be disabled.
The drive enable output can either be a digital output or the error output (see section 4.4.3). If
the NextMove ES is connected to a Baldor backplane with opto-isolating card, the error output
controls the relay.
1. In the Toolbox, click the Digital I/O icon.
2. At the bottom of the Digital I/O screen, click
the
Digital Outputs
tab.
The left of the screen shows yellow High and
Low icons. These describe how the output
should behave when activated (to enable the
axis).
3. If you are going to use the error output, ignore
this step and go straight to step 4.
If you are going to use a digital output, drag
the appropriate yellow icon to the grey OUT
icon that will be used as the drive enable
output. In this example, OUT1 is being used.
The icon’s color will change to bright blue.
4. If you are going to use
the error output, drag
the Relay0 icon to the
grey Drive Enable OP
icon on the right of the
screen.
Note:
The error output is represented by the Relay0 icon. This is because the error
output always controls a relay when the NextMove ES is used in conjunction with
an opto-isolating backplane. When the NextMove ES is not used with an
opto-isolating backplane, the Relay0 icon still represents the error output.
To configure multiple axes to use the error output, repeat this step for the other axes.
