Parameters for tension setup at zero speed in closed-Loop control mode
Generally, the AC drive can run without the need for additional configuration of
closed‑loop control.
Configure the following parameters in scenarios demanding accurate tension setup at
zero speed or roll diameter auto‑tuning during tension setup at zero speed.
Para.
No.
Name Default
Value Range Description
B1‑31
Tension setup at pre‑
speed
0
0: Disabled
1: Enabled
In closed‑loop control mode, if B1‑31 is set to 0, the
tension setup at pre‑speed function is disabled. If
B1‑31 is set to 1, the tension setup at pre‑speed
function is enabled.
B1‑32
Tension setup dead zone
2.0% 0.0% to 100.0%
When the tension setup at pre‑speed function is
enabled and PID feedback is below B1‑32, PID
calculation stops.
B1‑33
Pre‑speed of tension
setup
0.10 Hz 0.00 Hz to F0‑10
Used to set the running frequency in scenarios
where the tension setup at pre‑speed function is
enabled but the system is not in the tension setup
dead zone.
For details about tension setup at zero speed, see "
Figure 3–81 Diagram of tension
setup at zero speed
"
on page 655
. You can set B1‑31 to 1 to enable the tension setup
at pre‑speed function and set B1‑32 to define the tension setup dead zone.
When PID feedback is below the tension setup dead zone, PID calculation stops and
the reel runs at a fixed frequency to slowly wind the material.
