Motor brake and stop operation
(4) Regenerative brake duty alarm output
100%: regenerative overvoltage protection operation value
[RB] appears on the operation panel when 85% of the
regenerative brake duty set in Pr. 70 is reached. If the
regenerative brake duty reaches 100% of the Pr. 70
setting, a regenerative overvoltage (E.OV1 to E.OV3)
occurs.
Note that [RB] is not displayed when Pr. 30 = "0".
REMARKS
Refer to page 25 to 28 for connecting the brake resistor (MRS type, MYS type), high-duty brake resistor (FR-ABR) and brake unit
(FR-BU2).
WARNING
The value set in Pr. 70 must not exceed the setting of the brake resistor used.
Otherwise, the resistor can overheat.
