5.6 Inside Delta Operation
Adaptive control, jog, and brake functions are not
supported in inside delta (6-wire) operation. If these
functions are programmed when the soft starter is
connected inside delta, the behavior is as in Table 5.2:
Adaptive
control
start
The soft starter performs a constant current start.
Adaptive
control
stop
If stop time is >0 s, the starter performs a TVR soft
stop. If stop time is set to 9 s, the starter performs a
coast to stop.
Jog The soft starter issues a warning with the error
message Unsupported Option.
Brake The starter performs a coast to stop.
Table 5.2 Inside Delta Behavior at Adaptive Control, Jog,
and Brake
NOTICE
When connected in inside delta, current imbalance is the
only phase loss protection that is active during run. Do
not disable parameter 2-2 Current Imbalance during
inside delta operation.
NOTICE
Inside delta operation is only possible with mains
voltage ≤600 V AC.
5.7 Typical Start Currents
To determine the typical start current for an application,
use this information.
NOTICE
These start current requirements are appropriate and
typical in most circumstances. However, the performance
and start torque requirements of motors and machines
do vary. For further assistance, contact the local Danfoss
supplier.
