(1)
The first “_” equals either “P” for the Model 940 encoder based drive OR an “R” for the Model 941 resolver based drive.
(2)
The second “_” equals either “E” for incremental encoder (must have E94P drive) OR an “R” for the standard resolver (must have E94R drive).
(3) At 240 VAC line input for drives with suffixes “S1N”, “S2F”, “Y2N”. At 480 VAC line input for drives with suffixes “T4N”.
a. The output power is calculated from the formula: output power (kVA)
=sqrt(3) x U
LL
x I
rated
b. The actual output power depends on the motor in use due to variations in power factor.
(4) At 16 kHz, de-rate continuous current by 17%
(5) Installations with high fault current due to large supply mains may require a type D circuit breaker.
(6) UL Class CC or T fast-acting current-limiting type fuses, 200,000 AIC, preferred. Bussman KTK-R, JJN, JJS or equivalent.
(7) Thermal-magnetic type breakers preferred.
(8) DC-rated fuses, rated for the applied voltage. Examples Bussman KTM or JJN as appropriate.
