Deceleration Method
Factory Setting: 0
Settings 0: Normal decel.
1: Over fluxing decel.
2: Traction energy control
When Pr01-49=0, the deceleration or stop will according to original deceleration method.
When Pr01-49=1: drive will control the deceleration time according to the Pr06-01 setting value
and DC BUS voltage.
DC BUS >95% of Pr06-01
Over-voltage Stall Prevention setting value Æenable Over fluxing
deceleration method.
If the Pr06-01=0ÆDrive will enable Over fluxing deceleration method according to the operating
voltage and DC BUS regenerative voltage This method will refer to the deceleration time setting
and the actual deceleration time will longer than the deceleration time setting.
Actual deceleration time will longer than the deceleration time setting because the Over-voltage
Stall Prevention function.
When Pr01-49=1, please used with the parameter Pr06-02=1 to get a better over voltage
suppression effect during deceleration.
Pr01-49=2: this function is based on the drives’ ability to auto-adjust output frequency and voltage
in order to get faster DC BUS energy consumption and the actual deceleration time will be as
much as possible consistent with the deceleration parameter set up time. When real deceleration
time does not conform to the expected deceleration time and cause an over-voltage errors,
recommended that to use this setting.
