Star-delta changeover mode for star-delta starter 1:
defi nes when the UMC22 switches from star to delta.
Start surveying time for actuator 1-4:
defi nes whether the Start surveying time is prolonged or not.
Time
(0)
Sd.ti Time:
For star-delta starter 1:
Change from star to delta, when star-delta starting time is over
For actuator 1-4:
Start surveying time fi xed = 3 s
Current
(1)
Sd.cu Current (= default):
For star-delta starter 1:
Change from star to delta, when motor current 울 0,9 x Set current 1
Remark:
Current check-back fault is generated if the Star-delta starting time has
elapsed before switching to delta.
For actuator 1-4:
Start surveying time adjustable
= 3 s + 12.5 % of the parameter Run-time limit (Star-delta starting time).

Accessible via control system or Control Panel (menu point: ti.Sd (Edi.1))!
Star-delta starting time for star-delta starter 1:
defi nes the time when the UMC22 switches from star to delta or defi nes the surveying time
Run-time limit for actuator 1-4:
defi nes the prolongation of the Start surveying time

1-3600 s:
Adjustment via control system: step: 0.1 s: 1 s = 0.1 s x 10
Adjustment via Control Panel: step: 1 s: 1 s = 1 s x 1
Default value: 600 resp. 0060 (= 60 s)
