Input Power Cycle Capability
The power cycle capability is inversely proportional to the system capacitance
(including DC bus follower), but cannot exceed 2 contactor cycles per minute
with up to 4 axes or 1 contactor cycle per minute with 5…8 axes.
The cycle capability also depends on the converter power rating and the total
system capacitance. Refer to Appendix C on
page 225 to calculate total system
capacitance.
Table 43 - Maximum Input Power Cycling Specifications (230V)
Table 44 - Maximum Input Power Cycling Specifications (460V)
For example, in a 4 axis system with a 2094-BC02-M02-S IAM module and
2,000 μF total capacitance, the calculated capability is 0.52 x 10,000/2000 = 2.6
cycles per minute. However, this value is reduced to 2.0 by the 4 axes per system
limitation.
