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
Built-in brake resistor
BU-
brake unit (option)
FR-ABR-
high-duty brake resistor (option)
FR-HC high power factor converter (option)
Do not set the Pr. 70 value which exceeds the setting of the brake resistor used.
Doing so will overheat the brake resistor.
Unit
The motor starts coasting the preset time after the start signal has
turned "OFF".
s
If the start signal is turned "ON" within the preset time, coasting to a
stop is made invalid and operation continues.
This function is made invalid.
