When using a brake resistor (excluding FR-ABR)
A brake resistor can be applied to FR-A820-01250(22K) or lower and FR-A840-01800(55K) or lower.
Use a brake resistor that has resistance and power consumption values higher than the following. Al-
so, the brake resistor must have a sufficient capacity to consume the regenerative power.
Set parameters as below.
●
Pr. 30 "Regenerative function selection" = 1
●
Set Pr. 70 "Special regenerative brake duty" according to the amount and frequency of the
regenerative driving, and make sure that the resistor can consume the regenerative power
properly.
