- Braking time (F17)
F17 specifies the braking period that activates DC braking.
-
Braking response mode (H18)
H18 specifies the DC braking response mode.
Data for H18 Characteristics Note
0
Slow response. Slows the rising edge of the current,
thereby preventing reverse rotation at the start of DC
braking.
Insufficient braking torque may result at the
start of DC braking.
1
Quick response. Quickens the rising edge of the
current, thereby accelerating the build-up of the
braking torque. Reverse rotation may result depending on
the moment of inertia of the mechanical load
and the coupling mechanism.

Status variables
The status variables are the read-only type and supply information regarding the status of the RVBS
including control, maintenance, and network or other general information. For example, the variables inform
regarding the drive temperature, frequency/current/voltage supplied, the DC bus voltage, the number of drive
switch-on hours, the number of functioning hours with the motor running for entire period and for the period
from last alarm. Regarding the characteristic data of the RVBS, firmware version is available.
The frequency reference set via analog input is displayed in function code D17
