Description
B1‑03
Zero‑speed
threshold
0.0% 0.0% to 20.0%
If the running frequency is lower
than the value of this parameter,
startup friction tension
compensation will be carried out
according to B1‑04. If the running
frequency is higher than the value
of this parameter, startup friction
tension compensation will not be
carried out.
B1‑04
Zero‑speed
tension rise
0.0% 0.0% to
100.0%
This parameter corresponds to
the percentage of the tension
reference and must be set
properly according to the range of
allowable material tension. Set
this parameter to a value as small
as possible on the premise of
ensuring normal startup.
B1‑14
Transition
frequency for zero
speed
compensation
2.00
Hz
0.00–200.00
Hz
This parameter supports smooth
switchover of zero speed tension
rise at the threshold.
The preceding three parameters can be used together for static compensation, as
shown below.
