Contactor Enable Relay
Contactor enable is a relay-driven contact used in the three-phase power-
enable control string to protect the drive electronics during certain fault
conditions. It is capable of handling 120V AC or 24V DC at 1 A or less.
Contactor enable is a function of the converter and is not available in the axis
modules. An active state indicates the drive is operational and does not have a
fault.
Figure 32 - Contactor Enable Relay Circuit
Table 41 - Contactor Enable Relay Output Specifications
ATTENTION: Wiring the contactor enable relay is required. To avoid personal
injury or damage to the drive, wire the contactor enable relay into your
three-phase power-enable control string so that:
• three-phase power is removed from the drive in the event of shutdown
fault conditions.
• drive operation is prevented when the power rail is not fully populated.
• control power is applied to the drive prior to three-phase power.
Refer to IAM Module (without LIM module) on page 192
for a wiring
example.
IMPORTANT All power rail slots must have a module installed or the contactor enable
relay does not close.
