4.7 Connection summary - minimum system wiring
As a guide, Figure 21 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 24 V 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 Mint
Event IN0
event.
The
INPUTACTIVELEVEL
keyword can be used to alter the
active state of the digital input.
