8 PARAMETER FUNCTIONS
8-30
Initial value
Pr. 250 "coasting-to-stop setting" 9999
Set this parameter to coast the motor to a stop when the start signal is turned "OFF".
Setting Range Unit Operation
0.0 to 100.0 s
The motor starts coasting the preset time after the start signal has
turned "OFF".
If the start signal is turned "ON" within the preset time, coasting to a
stop is made invalid and operation continues.

8.5.5 Selection of regenerative brake unit
Initial value
Pr. 30 "regenerative brake option selection" 0
Pr. 70 "regenerative brake duty" 3
Pr. Setting Range Unit
30 0, 1, 2
70 0.0 to 15.0 %
Set Pr. 30 and Pr. 70 according to the regenerative brake unit used. At the setting of Pr. 30 = 0, the
Pr. 70 "regenerative brake duty" value is fixed at 3% and Pr. 70 cannot be read.
When Pr. 30 = 1, set the value given in the following table since Pr. 70 setting is enabled.
When Pr. 30 = 2, the built-in brake circuit is disabled.
Regenerative Brake Option Pr. 30 Pr. 70
Built-in brake resistor 0
BU-
brake unit (option) 0
FR-ABR-
high-duty brake resistor (option) 1 10
FR-HC high power factor converter (option) 2
CAUTION
Do not set the Pr. 70 value which exceeds the setting of the brake resistor used.
Doing so will overheat the brake resistor.
