HO W DO I …
CONNECT AN OUTPUT CONTACTOR?
You may use an output contactor with the Model 1000AR.
You MUST interlock the contactor with the Emergency Stop. You
WILL damage the drive if you do not interlock the contactor.
Requirements for the Model 1000 series are:
1. The contactor must close its main power contacts
BEFORE it enables the drive;
2. The contactor may only open its contacts AFTER
disabling the drive.
The contactor does not make or break current.
The figure at left shows the connections for a 48VDC output
contactor (such as AEG part number SH-04.40-ODC, which is
available from POWERTEC).
In this configuration, the contactor pulls in on a run
command and drops out ONLY on an emergency stop. The
contactor stays energized during normal stops.
POWERTEC makes an optional track mount PC board (Part
# 156-012) for sequencing of contactors with AC coils.
DO NOT BREAK THE GROUND CONNECTION OR THE CABLE
CONNECTIONS WITH THE OUTPUT CONTACTOR.
HO W DO I …
CONNECT DYNAMIC BRAKING?
You MUST interlock the contactor with the
Emergency Stop when using Dynamic Braking. You will
damage the drive and/or the resistor banks if you do not
properly interlock the contactor.
The requirements are:
1. The contactor must open the main power
contacts BEFORE the drive is enabled; AND
2. The contactor may only close its contacts
AFTER disabling the drive.
The AEG SH-04.13-ODC contactor is suitable to
the circuitry above. The figure on the left shows how to
use a POWERTEC 156-012 Contactor Control board to
control a larger contactor or a contactor with an AC coil.
In this configuration, the contactor energizes on a
run command and drops out ONLY on an emergency
stop. The contactor stays energized on a normal stop.
