dc injection braking time at stop.
used to set the time to perform dc injection braking(initial excitation for flux vector control)in units of 1 second .
note: to set b2-04 to be the dc braking performing time until te motor stops. used to prevent the motors coasting when the motor is not working .
magnetic flux compensation volume.
the compensation value of magnetic flux is set as a percentage of idle load current with taking the idle load current as 100%.
note: when b2-08 is set to be 100%'the dc braking current(initial excitation) at start will be comparatively big at the beginning and the flux in the motor can arrive very soon. when b2-08 is set to be 200%'the arriving time will be cut to be the half.
normally 'do not set b2-08 to be below 00%'since the flux arrive slowly' however the operation when b2-08=0%and b2-08=100% is same and both of the flux are achieved via setting of dc injection current (b2-02).
as the flux compensation value (b2-08) is increased the starting sound of the motor will be bigger.
the time parameters when the motors flux reach to a certain value are set by e2 and can be computed by the following formula. time of the secondary circuit t2={(e2-012-e2-032)/(2~xe2-02xe2-03)}.
when the control start was deferred because of the setting of b2-03 please do not use the funtion flux compensation but to use the dc braking command of multi-function input terminal (set the value to be 60)and establish a Magnetic field according to the motors flux before it stops .
