Simplified Resistor Selection
Many applications do not require a power-dump resistor because the
drive/controller can absorb or dissipate the regenerative deceleration energy.
However, if a drive/controller faults from over-voltage during a deceleration
event, an external power dump resistor is probably required.
Table 38 contains recommended power-dump resistors for specific
drive/co
ntroller and Parker Hannifin motor combinations. The
recommendations are based on the calculations presented in the section
Calculating Resistance—Rotary Motors. These re
commendations assume a
worst-case load-to-rotor inertia ratio of 10 to 1, maximum duty cycle and
maximum deceleration from maximum velocity for that specific motor/drive
pairing.
These are recommendations only—while not optimized for your particular
application, they will work in most situations.

1. External power dump resistor not needed. However, higher operating voltage, higher load to rotor inertia ratio, and
higher duty cycles can increase the need.
2. Higher friction loads, lower speeds, lower deceleration rates, lower load to rotor inertia ratio, and lower duty cycles
can decrease the need for this resistor.
3. Minimum resistance allowed for AR-13 is 22 Ohms, therefore the maximum deceleration rate and/or duty cycle may
need to be reduced.
4. Isotek resistor or equivalent
