Fig.8-8: Stopping DC braking
For the actual stopping DC braking current calculation, see descriptions in
parameter [b1.30].
b1.44 Reserved
b1.45 Overexcitation deceleration gain
Setting range 1.00 ~ 1.40
Minimum unit 0.01
Factory default 1.00
“Overexcitation deceleration gain” is a gain to the V/F pattern needed for fine-tune of
this function which determines the level of overexcitation.
● Higher value of gain will increase the braking capability of overexcitation.
● Reduce the value of [b1.45] when the motor slip gets too high, which can trigger
overcurrent (OC), frequency converter overload (OL-1), or motor overload (OL-2)
faults.
