Chapter 2 Servo Drive and System Comparison
Contactor Enable Relay
In Kinetix 5700 drive systems, the contactor-enable circuitry includes a relay-
driven contact within the 2198-Pxxx DC-bus power supply. In Kinetix 6000
drive systems, the contactor enable relay resides in the IAM module. The relay
helps protect the drive system if overloads or other fault conditions occur.
An AC three-phase mains contactor must be wired in series between the
branch circuit protection and the DC-bus power supply. In addition, the AC
three-phase contactor control string must be wired in series with the contactor-
enable relay at the contactor-enable (CED) connector.
Shunt Modules
Kinetix 6000 drive systems use the 2094-BSP2 shunt module when the IAM/
AM module internal shunt-resistor capacity is exceeded. If additional shunting
capacity is needed, the 2094-BSP2 shunt module can be coupled with a
1394-SRxxx external passive shunt module.
For the Kinetix 5700 replacement system, we recommend Motion Analyzer to
determine if the 2094-BSP2 shunt module and if an external shunt module are
required. Observe the following guidelines when mounting your 2198-Rxxx
external passive shunt module:
• Mount the shunt module outside of the drive system enclosure. Only the
2198-R004 shunt resistor can be mounted inside the enclosure.
• Mount the shunt module so that wiring routes in the very dirty zone
(inside the drive system enclosure)
• Keep unshielded wiring as short as possible, not to exceed 3 m (9.8 ft)
and keep shunt wiring as flat to the cabinet as possible
• Separate shunt power cables from other sensitive low-voltage signal
cables
ATTENTION: Wiring the contactor-enable relay is required. To avoid personal
injury or damage to the drive, wire the contactor-enable relay into your
control string. By using the contactor-enable relay:
• Three-phase power is removed, which helps protect the DC-bus power
supply under various fault conditions
• Three-phase power is never applied to the drive system before control
power is applied
