High-function General-purpose Inverter RX2 Series User’s Manual
Assign 030 [DB] to input terminal functions [CA-01] to [CA-11].
When [AF101]=00 or 01, DC braking will be applied depending on whether the [DB] terminal is on.
Adjust the braking force by adjusting the [AF105] DC braking force.
When you set the [AF104] DC braking delay time, the inverter output will be shut off within the set
period of delay, and the motor will run freely during the period. (Ex.11), (Ex.14)
DC braking will be restarted after the set period has elapsed.
Select the braking mode by the DC braking/edge or level selection [AF107], and then make any other
necessary settings suitable for your system.
When [AF107]=00: After [DB] is turned on, the inverter performs DC braking for the time set for [AF106]
. (Ex.9) to (Ex.11)
When [AF107]=01: The inverter performs DC braking only when [DB] is on. (Ex.12) to (Ex.14)
Precautions for Correct Use
• When setting [AF105] DC braking force, [AF106] DC braking time, or the ON time of the [DB]
terminal (input terminal function 030), pay attention to the heat generation on the motor.
• The setting for the [DB] terminal is given priority over operation commands. (Ex.9), (Ex.12)
• If the [DB] terminal is turned on when the motor speed is high, an overcurrent error or an
overvoltage error may occur.
• When the [DB] terminal is turned on, DC braking mode that occurs when “00” is specified for
[AF102] Braking mode selection is performed regardless of the setting for [AF102].
