VersiStart p III
9.11 Inside Delta Operation
When connecting in inside delta, enter the motor full load current (FLC) for
parameter 1B. The VersiStart p III will automatically detect whether the motor is
connected in-line or inside delta and will calculate the correct inside delta current
level.
Adaptive Control, Jog, Brake and PowerThrough functions are not supported with
inside delta (six-wire) operation. If these functions are programmed when the
starter is connected inside delta the behaviour is as given below:
Adaptive Control Start
The starter performs a constant current start.
Adaptive Control Stop
The starter performs a TVR soft stop if parameter 2J
Stop Time
is >0 secs.
If parameter 2J is set to 0 secs the starter performs a
coast to stop.
Jog
The starter issues a warning with the error message
Unsupported option.
DC Brake
The starter performs a coast to stop.
Soft Brake
The starter performs a coast to stop.
PowerThrough
The starter trips with the error message Lx-Tx Shorted.
NOTE
When connected in inside delta, the VersiStart p III will not detect phase
loss on T2 during run.
9.12 Secondary Motor Set
The VersiStart p III can be programmed with two separate starting and stopping
profiles. This allows the soft starter to control the motor in two different starting and
stopping configurations.
This is ideal for situations where the motor may start in two different conditions
(such as loaded and unloaded conveyors).
The VersiStart p III will use the secondary motor settings to control a start when
instructed via a programmable input (refer to parameter 7A
Input A Function
and 7E
Input B Function
).
NOTE
VersiStart p III soft starters are not suitable for controlling two separate
motors. The secondary parameter set should only be used for a secondary
configuration of the primary motor.
