Appendix A-3: Ca R21 Settings – Normal Ramp Rate (Rr) & Soft-Start Ramp Rate (Ss) - Delta M42U Operation And Installation Manual

Appendix A-3: CA R21 Settings – Normal Ramp Rate (RR)
& Soft-Start Ramp Rate (SS)
a) Output Current Rating (A)
b) Minimum normal ramp-up rate (%Irated /sec)
c) Maximum normal ramp-up rate (%Irated /sec)
d) Minimum output current
e) Ramp Rate Accuracy MSARR(%Irated /sec)
Appendix A-4: CA R21 Settings – Soft-start ramp rate test
a) Output Current Rating (A)
b) Minimum soft start ramp-up rate (%Irated /sec)
c) Maximum soft start ramp-up rate (%Irated /sec)
d) Ramp Rate Accuracy MSARR(%Irated /sec)
Appendix A-5: CA R21 Settings – Specified Power Factor
a) Apparent Power Rating (VA)
b) Output Power Rating (W)
c) DC Input voltage range with function enabled (V)
d) Nominal AC voltage (V)
e) AC voltage range with function enabled (V)
f) AC voltage measurement accuracy (V)
g) DC voltage measurement accuracy (V)
h) Active power range of function, e.g., 20-100% of nameplate
i) Power Factor Accuracy
j) Power Factor Settling Time
k) Minimum Inductive (Underexcited) Power Factor
l) Minimum Capacitive (Overexcited) Power Factor
m) PF, the inductive or capacitive signed power factor
commanded for test
n) PFmid,cap = (1 + PFmin,cap)/2, middle of the EUT
capacitive range.
o) PFmid,ind = (1 + PFmin,ind)/2, middle of the EUT
inductive range.
p) POutlimit, the maximum output power either limited by the
input supply or by a command to the inverter.
q) PFtarget, the target power factor. This will differ from the
commanded power factor in 'Active Power Priority' modes
for input power greater than PX
