Programming Your Application 1-1
650V AC Drive
1PROGRAMMING YOUR APPLICATION
You can program the drive to your specific application. This programming simply involves
changing parameter values. Access the parameters using the keypad, or ConfigEd Lite (or other
suitable programming tool).
Each Application recalls a pre-programmed set of default parameters and links when it is
loaded.
Refer to Chapter 5: “Applications” for further information.
Programming with Block Diagrams
Block diagram programming provides a visual method of planning the software to suit your
application. There are block diagrams provided at the end of this chapter, each showing the
software connections for an Application. These pages replicate the ConfigEd Lite programming
screens. ConfigEd Lite is SSD Drive’s own programming tool.
The processes performed by an Application are represented as a block diagram, consisting of
function blocks and links:
•Each function block contains the parameters required for setting-up a particular processing
feature. Sometimes more than one instance of a function block is provided for a feature, i.e.
for multiple digital inputs.
•Software links are used to connect the function blocks. Each link transfers the value of an
output parameter to an input parameter of another (or the same) function block.
Each individual block is a processing feature, i.e. it takes the input parameter, processes the
information, and makes the result available as one or more output parameters.
Modifying a Block Diagram Over Comms
Configuration and Parameterisation Modes
There are two modes of operation used while modifying a block diagram:
Configuration and Parameterisation modes.
Configuration Mode
In the Configuration Mode you can modify the links in the function block diagram.
You can also change parameter values, as above. The drive cannot run in this mode.
When you attempt to change a parameter value requiring Configuration Mode to be
enabled, the drive automatically enters Configuration Mode.
Once in Configuration Mode, to return to Parameterisation Mode simply press the E
key repeatedly.
Parameterisation Mode
In parameterisation mode you can change parameter values. The drive can be running
or stopped. Note that some parameters can only be changed when the drive is stopped.
It is not possible to modify the internal links when the drive is in parameterisation
mode.
DEFAULT

1-2 Programming Your Application
650V AC Drive
Execution Rules
The complete block diagram is executed every 5ms. Just before a function block is executed, all
the links that have that block as their destination are executed, thereby copying new values in to
the block’s parameter inputs. The input parameters are then processed to produce a new set of
output parameters. The execution order of the blocks is automatically arranged for minimal
delay.
•The output value transferred by a link on execution is clamped to be between the maximum
and minimum value for its destination input parameter.
•Refer to the table below for the result of linking different parameter types.
Source Value
(the input)
Source Type Destination
Type

2.00 Real Enumerated REMOTE ONLY (2) (Note that (2) will not
always return Remote Only)

Saving Your Modifications
Whenever a value/link is changed, the modification is stored automatically and will be saved on
power-down.

1-6 Programming Your Application
650V AC Drive
Functional Description
The drive has two analog inputs. There is an analog input function block for each:
ANALOG INPUT 1 is associated with the signal on terminal 2
ANALOG INPUT 2 is associated with the signal on terminal 3
The input voltage is pre-processed and converted into a numeric value by the analog input
electronics of the drive. The analog input function blocks further process this reading so that a
value of 0.00% represents an input equal to the low input range, while a value of 100.00%
represents an input equal to the high input range. The SCALE and OFFSET factors are then
applied as shown to produce a value suitable for use in the application.
The break detect facility is only used in conjunction with the "4 to 20mA" hardware range. An
input break is defined as an input reading less than either 0.1V or 0.45mA. When an input break
has been detected, the VALUE output is forced to be the BREAK VALUE.
If you don't want the break detect facility, select the "0 to 20mA". You can also apply OFFSET
to recreate the "4 to 20mA" hardware range.

AUTO RESTART
Auto Restart (or Auto Reset) provides the
facility to automatically reset a choice of trip
events and restart the drive with a
programmed number of attempts, after
which, a manual or remote trip reset is
required if the drive is not successfully
restarted. The number of attempted restarts
are recorded. This count is cleared after a
trip-free period of operation
(5 minutes or 4 x ATTEMPT DELAY 1,
whichever is the longer), or after a successful manual or remote trip reset, or by removing the
Run signal.
In addition, if the POWER UP START parameter in the SEQUENCING LOGIC function block
is True, then the Auto Restart feature will also operate even if the trip initially occurs when the
drive is not running (as long as the Run signal remains True).

model parameters. The motor model is used
by the Sensorless Vector control mode. You MUST perform an Autotune before operating the
drive in the Sensorless Vector control mode.
Refer to the Installation Product Manual, Chapter 4: “Operating the Drive” - Set-up using the
Sensorless Vector Fluxing Mode.
Functional Description
The Autotune sequence identifies the following motor parameters:-
•Per-phase stator resistance (STATOR RES)
•Per-phase leakage inductance (LEAKAGE INDUC)
•Per-phase mutual inductance (MUTUAL INDUC)
•Rotor time constant (ROTOR TIME CONST)
•No-load magnetising line current (MAG CURRENT)
The Rotating Autotune sequence rotates the motor up to the user-programmed MAX SPEED
(REFERENCE function block) in order to identify these parameters.
The Stationary Autotune sequence does not rotate the motor and requires the correct value of
Magnetising Current to be entered.
The values of the above are stored in the MOTOR DATA function block. Autotune will
overwrite any previous entry made for these parameters. Autotune can only be initiated from the
“stopped” condition. When the test is complete, the stack is disabled and ENABLE is set to
FALSE.

Parameter Descriptions
ENABLE SV SET\CTRL CL21 Range: FALSE / TRUE
Determines whether the Autotune sequence is operational or not. The Autotune sequence is
operational when set to TRUE and the drive is run. Refer to the Installation Product Manual,
Chapter 4: “Operating the Drive” - The Autotune Feature.
MODE SV SET\CTRL CL20 Range: Enumerated - see below
Selects the Autotune operating mode. Refer to the Installation Product Manual, Chapter 4:
“Operating the Drive” – The Autotune Feature.
Enumerated Value : Mode
0 : STATIONARY
1 : ROTATING
ACTIVE Range: FALSE / TRUE
This indicates the current state of the Autotune sequence. The Autotune sequence is
operational when displaying TRUE.
