7.5.2 Description
With
Star-delta starter 2
the outputs DO0 (star) and DO1 (delta) are defi ned to drive the motor contac-
tor coils. The main contactor is controlled via auxiliary contacts of the star and delta contactors.
Once the motor is started with RUN FORWARD the star-delta-sequence is controlled automatically by
the UMC22.
7.5.2.1 Attached control functions
(4.3.1)
The parameter set Attached control functions prepare the star-delta starter 1 to support different cir-
cuit arrangements including the use of inputs and outputs for particular use.
Examples:
Star-delta changeover mode
(4.3.4)
Star-delta changeover mode = Current
(default):
The UMC22 switches from star to delta when the current decreases under 90% of the set current.
Additional the parameterizable
Star-delta starting time
(default 60 s) is started. If this time has
elapsed the UMC22 must be in delta mode otherwise Current check-back fault is signalled and the
motor is stopped.
Star-delta changeover mode = Time
:
The UMC22 switches after the parameterizable
Star-delta starting time
(default 60 s).
The transition time star to delta is fi xed 50 ms after current is 0 or auxiliary contacts are open resp.
Fault output
(4.3.4)
Activate via Parameter
Fault output = On
:
If a fault appears
- the output contact DO2 closes and
- the internal fault signal is set.
Multi-function inputs DI0, DI1 and DI2
(4.3.4)
Depending of the parameterization of the parameters
DI0 Multi-function input
,
DI1 Multi-function input
and
DI2 Multi-function input
the following functions are possible:
Transparent
(default): status is monitored only to the fi eldbus
Fault signal always / not delayed or delayed
with 1 to 255 s:
The delay time starts whether the motor is running or not.
Fault signal dependent / delayed
with 1 to 255 s:
The delay time starts only when the motor is running.
Motor off always / not delayed or delayed
with 1 to 255 s:
The delay time starts whether the motor is running or not.
Motor off dependent / delayed
with 1 to 255 s:
The delay time starts only when the motor is running.
Reset internal fault signal
Prepare emergency start
: Reset of the thermal memory and of other faults.
Test
Start without motor (no current check-back when started)
Remark:
DI0, DI1 and DI2 can be parametrized via fi eldbus. Only DI2 can be parametrized via Control Panel.
Setting
Check-back = Auxiliary contacts
and
DI0 Multi-function input = not 000
give the input DI0
two colliding tasks.
As a result the internal fault signal is set and monitored via different ways, e.g. Parameter out
of range / F004 (4.2.1). The motor cannot be started.
DI0: can not be parameterized as Fault signal not delayed (reason: compatibility to older versions)
Local control via digital inputs
(4.3.4)
Activate via parameter
Local operation via DIs = On
,
02, 003, 004, 008 or 009
:
- DI4 to start the motor, only via active signal possible
- DI5 to stop the motors, depending on the parameterization via closed circuit or active signal possible
