Note: This function is disabled during acceleration/deceleration process.
0: Magnetic flux braking disable
1: Magnetic flux braking enable
When the motor decreases, the inverter can rapidly slow down if magnetic flux braking action is selected.
Then the electric energy can be transformed to heat energy during the braking process.
Rapid deceleration can be realized by selecting magnetic flux braking action, but the output current will
be larger. Selecting no action, the deceleration will last longer, but the output current will be smaller.
Determine whether to use energy consumption braking using braking unit selection PA.09.
0: Energy consumption braking disable
1: Energy consumption braking enable
For large rotating inertia applications and when rapid stop by braking is required, select matched braking
unit and braking resistance and set braking parameter for the motor stop rapidly by braking.
Braking unit operating time PA.10 and braking unit action voltage PA.11 are only applied to inverter with
built
−
in braking unit.
Braking unit action cycle is fixed to be 100s. If PA.09 is set as 1, the use rate of the braking unit is fixed to
100%. That is, the use time of the braking unit is fixed to 100.0s
Action voltage of braking unit can be selected by adjusting PA.11. The motor can be stopped rapidly by
energy braking with the appropriate action voltage.
Note: Set PA.09 to 1 when using braking unit. For model selection of braking unit parts and connection,
refer to 1.9 braking unit model selection.
Generally, when inverter produces a failure alarm, the relay will make corresponding indication action.
With this function, the action of error relay terminal can be set under some special conditions.
