Installation and Configuration
Soloist HPe 150/200
Equation 2:
C
bus capacitor (F) [4,700 uF]
V
M
turn on voltage for shunt circuit (V) [380 V]
V
NOM
nominal bus voltage (V) [160 V or 320 V, Typical]
For a standard Soloist HPe 150/200, the maximum additional energy the internal bus capacitor can store
without requiring a shunt resistor is indicated in
.
Table 2-43:
Maximum Additional Storage Energy
Bus Voltage
Maximum Additional Energy
160 V
279.2 J
320 V
98.7 J
If a shunt resistor is required, the next step is to calculate the value of resistance necessary to dissipate the
energy. Use
Equations 3
,
4
, and
5
to calculate the parameters of the shunt resistor.
Equation 3:
P
PEAK
peak power that the regeneration circuit must accommodate (W)
t
D
deceleration time (s)
Equation 4:
P
AV
average power dissipated on shunt resistor (W)
t
CYCLE
time between deceleration events (s)
Equation 5:
V
HYS
hysteresis voltage of regeneration circuit (V) [10 V, Typical]
Additional useful equations:
1 lb·ft = 1.356 N·m
1 rad/s = 9.55 rpm
