Regeneration Protection The Aries drive models AR-20xE and AR-30xE have internal regeneration
power dump (dissipation) resistors. Models AR-01xx through AR-13xx do
not. However, all models can utilize an external regeneration resistor.
Regeneration Connection
To use a external regeneration (power dump) resistor, connect your external
resistor to the R+ and R- terminals as follows:
• For models AR-01x to AR-13xx, use the Mains connector.
• For models AR-20xE and AR-30xE, use the Control connector.
Figure 25 illustrates the external regeneration resistor connections.
Figure 25 External Regeneration Connection
Important! For models AR-20xE and AR-30xE, you must remove the
factory-installed link between RINT and R− when you connect the
external regeneration resistor. (Otherwise the internal regeneration
resistor will still be in the circuit, and its thermal protection circuit limits
the performance).
For information on selecting a suitable external regeneration (power dump)
resistor, see “Appendix B External Power-Dump Resistor Selection.”
Warning — The drive’s connector strip terminals are at hazardous voltages
when power is applied to the drive, and up to several minutes after power is
removed. Lower voltages may still be present for several minutes after power
is removed.
During normal operation, these high voltage terminals must not be accessible
to the user.
