H95 specifies the DC braking mode as follows:
Data for H95 Braking mode Meaning
0 Slow response
The DC braking current gradually ramps up. (The torque
may not be sufficient at the start of DC braking.)
1 Quick response
The DC braking current quickly ramps up. (Depending
on the inertia of the moving loads or the coupling state,
the revolution may be unstable.)
For three-phase 230 V and single-phase 230 V inverters
The braking level setting for the three-phase 230 V and single-phase 230 V series
should be calculated from the DC braking level I
DB (A) based on the reference current
