Fig. 12-29: Stop DC-braking
Overexcitation braking
This function is used to obtain an optimized braking performance of the fre-
quency converter in V/f control mode. To realize this function, increase 'Convert-
er output voltage' by fine tuning of parameter E0.55 'Overexcitation braking fac-
tor' during deceleration process.
Code
Name Setting range Default Min. Attri.
E0.55 Overexcitation braking factor 1.00...1.40 1.10 0.01 Run
● When [E0.55] = 1.00, 'Overexcitation braking' is inactive.
● A higher factor brings a higher braking force.
However, an excessive high factor may trigger errors of overcurrent (OC-1,
OC-2, OC-3), converter overload (OL-1), or motor overload (OL-2). Reduce the
setting of the factor in such cases.
