Contactor Enable Relay
Contactor enable is a relay-driven contact used in the safety 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.

Table 32 - 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 safety 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 204
for a wiring
example.
IMPORTANT
All power rail slots must have a module installed or the contactor enable
relay will not close.
