Commissioning Hints
:
TensionOn [WCW Bit 8]:
Aktivates
the independant torque limits of the speed controller [20.24 / 20.25] while switching from speed
control
(TensionOn == FALSE) to torque control (TensionOn == TRUE && speed controller output limited).
S
ee also signal CtrlMode [1.25]. If TensionOnCmd [61.07] = Auto then new independant torque limits [20.24 /
20.25]
are aktivated with the appropriate sign or deaktivated, respectively if this is necessary (E-Stop etc. with
Direc
t / Indirect Tension Control).

DiameterAct (diameter calculation)
In most cases, the actual diameter must be calculated
from the line speed - see SpeedRef3 (2.02) - and
measured motor speed
- see MotSpeed (1.04), because a diameter sensor does not exist. This is done by
means of DiaLineSpdIn (62.01) and DiaMotorSpdIn (62.02):
