E5 Series High Performance Universal Inverter
PA.08
0: Magnetic flux braking is disabled
T: Magnetic flux braking is enabled
When the motor decreases, the motor can be rapidly decelerated if magnetic flux braking is selected. The
energy of the mechanical system is changed to thermal energy in the motor during the braking process.
But if the function is selected, the output current will be larger than the function is not selected.
PA.09
The parameter of PA.09 enables the dynamic braking function.
0: Dynamic braking is disabled
T: Dynamic braking is enabled
For large rotating inertia applications and when rapid stop by braking is required, select matched braking
unit and braking resistance and setting PA.09 to T.
Note:
If external braking unit is installed, you also need to set this parameter to T.
PA.T0
PA.TT
Braking unit action voltage PA.TT is only applied to inverter with built-in braking unit. Action voltage of
braking unit can be selected by parameter PA.TT. The motor can be stopped rapidly by energy braking
with the appropriate action voltage.
Note:
Setting PA.09 to T when using braking unit. For built-in braking unit and braking resistor, refer to T.9.
PA.TT
Generally, when inverter produces a fault, for some special fault, the fault output can be set independent.
Ones place is used to enable the under voltage fault output. Under low voltage status, such as during
power on, during power off, under voltage, select the fault output is enabled or disabled by multi function
output terminal.
Tens place is used to enable the fault output during automatic reset interval period. The real fault is not
output during automatic reset interval period by default setting. Refer to PA.TT and PA.TT instructions.
Hundreds place is used to set the fault locking function, If fault locking function is enabled, if there was a
fault during the last outage, the fault will still be output after power on next time. Refer to PA.T0
instruction.
