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

Pr. 30 "regenerative function selection"
Pr. 70 "special regenerative brake duty"
y When making frequent starts/stops, use the optional "brake resistor" to increase the
regenerative brake duty. (more than 0.4K)

Setting
30
70
<Setting>
( 1 ) W hen using the brake resistor (M RS), brake unit, high pow er factor converter
y Set "0" in Pr. 30.
y The Pr. 70 setting is made invalid.
( 2 ) W hen using the brake resistors (2 M YSs in parallel) (3.7K is only allow ed)
y Set "1" in Pr. 30.
y Set "6%" in Pr. 70.
( 3 ) When using the high-duty brake resistor (FR-ABR)
y Set "1" in Pr. 30.
y 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)
3. The brake resistor cannot be connected to 0.1K and 0.2K inverters.
The value set in Pr. 70 should not exceed the value set to the brake
resistor used.
Otherwise, the resistor can overheat.
