3.10 Internal/External Regeneration (Regen) Resistors – Configurations
Regeneration resistors can be fitted to all DS2100 servo-drives. All external Regen resistors should be mounted to allow
adequate heat dissipation and such that heat from the Regen resistor is not directed to air intakes of other equipment. The
mA size DS2100 is the only size with internal regen. All other drive sizes use external regen only.

Table 3.13 Recommended Regeneration Resistors
For EMC purposes, use shielded cable to connect the external Regen resistor to
the DS2100. The length of this cable should be as short as possible. The shields
of these cables should be connected to Chassis Earth using the optional EMC kit
or the panel earth bar. Alternatively, if the cable is required to pass through an
enclosure panel earthed to Chassis Earth, the shield may be earthed to the panel
by use of a 360 degree metal cable gland.
Refer to Section 2 for further safety and EMC requirements for cable
installation.
NOTE - The regeneration resistor (internal and external) are protected by
software. Setting the regen power and resistance parameters, allows the drive to
calculate the maximum allowable duty cycle for the regen transistor. The
software will clamp the regen duty-cycle at this level. If the drive tries to regen
at a greater level, an overvoltage error will occur.
WARNING - External regen resistors are connected to the DS2100 D.C. Bus
voltage that can reach 800 V d.c. Exposed metallic mounting parts of external
regen resistors must be connected to protective earth and the electrically
conducting parts mechanically shielded for safety. High voltage warning
stickers are also recommended.
