4.6 Connection summary - minimum system wiring

As a guide, Figure 14 shows an example of the typical minimum wiring required to allow the NextMove ES and a single axis stepper amplifier to work together. The optional opto-isolating backplane card BPL010-502 is shown. Details of the connector pins are shown in Table 4.

Notes:

In this example, the backplane’s relay contacts are being used to apply the 24V user supply to the drive amplifier’s Enable input.

The backplane’s relay is driven by the NextMove ES Error

Out signal. This signal may be controlled by the keywords

DRIVEENABLEOUTPUT, GLOBALERROROUTPUT or RELAY.

The drive amplifier’s Fault relay connections are shown connected to digital input 0. If an error occurs, it can be detected by using the MintMT Event IN0 event.

The INPUTACTIVELEVEL keyword can be used to alter the active state of the digital input.
