4.4.3 Error output - Error Out

The error output is available on pin b11. This 5V 100mA output can be used to stop external equipment in the event of an error. The output level can be controlled using jumpers JP3, JP4 and JP5 as shown in Table 2. The jumpers are situated at the top edge of the card.

Table 2 - Error Out level configuration

There are a number of methods for controlling the error output.

4.4.3.1RELAY keyword

If the NextMove ES is connected to an opto-isolated backplane (optional) the output directly controls the relay (see section 5.3.1.1). For this reason, the error output can be controlled by the RELAY keyword. The command RELAY=1 will enable the error output; the command RELAY=0 will disable it. This is true regardless of whether an opto-isolating backplane is connected.

4.4.3.2DRIVEENABLEOUTPUT keyword

The DRIVEENABLEOUTPUT keyword can be used to configure the error output as the drive enable output. For example, the command DRIVEENABLEOUTPUT.1=_RELAY0 will mean that the error output will be the drive enable output for axis 1. When axis 1 is enabled, the error output will be activated and the axis enabled. If multiple axes are configured to use the error output as their drive enable output, enabling one axis will enable all of them. Similarly, if one axis is disabled, all will be disabled.

The RELAY keyword cannot control the error output if is configured as a drive enable output.

4.4.3.3GLOBALERROROUTPUT keyword

By default, the error output is used as the global error output. In the event of an error on any axis, the global error output will be deactivated. This action overrides the state of the error output defined by other methods, such as the drive enable status or RELAY keyword. Alternatively, the GLOBALERROROUTPUT keyword can be used to configure a general purpose digital output to be the global error output.

See the MintMT help file for details of each keyword.
