Internal Regeneration Capability
The drive/controller may experience an over-voltage fault if the regeneration
exceeds the absorbent capacity of the drive/controller’s internal bus
capacitors, as shown in Table 22.
The availabl
e absorption varies, based on mains voltage and the
drive/controller’s internal capacitance. The various drives can absorb the
following amounts of regenerated energy in its internal capacitors.
Drive Absorbs (Joules)
120 VAC
Absorbs (Joules)
240 VAC
AR-04CE 57 19
AR-08CE 72 24
AR-13CE 104 35
Table 22 Regeneration Absorption
For more specifications about energy absorption by the drive/controller’s
capacitors, see Table 39 Drive Capacitor Absorption.
For mo
re information about selecting an external power-dissipation resistor,
see “Appendix B External Power-Dump Resistor Selection”.
Warning — The drive/controller’s connector strip terminals are at hazardous
voltages when power is applied, 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.
