H95 specifies the DC braking response mode as follows:
If H95 is
set to:
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 200 V and single-phase 200 V/100 V class series in-
verters
The braking level setting for the three-phase 200 V and single-phase
200 V/100 V class series should be calculated from the DC braking level
