PARAMETERS
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.
<Setting>
(1) When using the
built-in brake resistor, brake unit
• Set "0" in Pr. 30.
The Pr. 70 setting is made invalid.
(2) When using the external high-duty brake resistor
• Set "1" in Pr. 30.
• Set "10%" in Pr. 70.

70 0% 0 to 30%
Note:1. Pr. 70 "special 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 2%.
WARNING
The value set in Pr. 70 should not exceed the value set to the brake
resistor used.
Otherwise, the resistor can overheat.
