Regenerative Brake Duty (Pr. 30, Pr. 70) - Mitsubishi Electric FR-E 500 Instruction Manual

" Regenerative brake duty (Pr. 30, Pr. 70)

4.2.13 Regenerative brake duty (Pr. 30, Pr. 70)
Pr. 30 "regenerative function selection"
Pr. 70 "special regenerative brake duty"
! When making frequent starts/stops, use the optional "brake resistor" to increase the
regenerative brake duty.

Number Setting

<Setting>
(1) When using the brake resistor (MRS), brake unit, high power factor
converter
! Set "0" in Pr. 30.
! The Pr. 70 setting is made invalid.
(2) When using the brake resistors (2 MYSs in parallel) (3.7K is only
allowed)
! Set "1" in Pr. 30.
! Set "6%" in Pr. 70.
(3) When using the high-duty brake resistor (FR-ABR)
! Set "1" in Pr. 30.
! Set "10%" in Pr. 70.
Note: 1. Pr. 70 "regenerative brake duty" indicates the %ED of the built-in brake
transistor operation. The setting should not be higher than the permissible
value of the brake resistor used. Otherwise, the resistor can overheat.
2. When Pr. 30 = "0", Pr. 70 is not displayed but the brake duty is fixed at 3%.
(Fixed at 2% for 5.5K, 7.5K)
The value set in Pr. 70 should not exceed the value set to the brake
resistor used.
Otherwise, the resistor can overheat.
