Figure 1-3.
The SHUNT500 board, shown in Figure 1-5, is an integral option to the DR500 used to
regulate either one or both of the bus power supplies (both, if supplies are connected
together). Typically, the SHUNT500 board is required for motors operating from a 160
VDC bus with large inertial loads, which, on deceleration, return the energy back into the
power supply, potentially damaging the drive module. The SHUNT500 board prevents
the power from entering the power supply by dissipating the excess energy into a 95 watt
resistive load.
If the board's dissipation limit is exceeded, the SHUNT500 board has an adjustable
voltage set point and fusing. The set point for the regulator is factory set and should not
require user adjustment. However, it may be necessary to change the fuse for the
regulator circuit. This is accessible by removing the front panel to access the fuse. There
are two possible mounting locations for the SHUNT500 board, refer to Figure 1-4. If the
SHUNT500 board is used to regulate the bus power supply connected to axis 1, the
mounting location is on the side of the divider that supports the card rails. Otherwise, the
board is mounted to the right side of the chassis to regulate the bus power supply
connected to axis 4.

on rail, 4 hole points from support panel,
using resistor mounting hardware
(EIH00456).
