Testing the operation in local control mode


Before first start and energy storage connection, check that the DC bus voltage is above the energy
storage voltage. Select the local control before start command (see section
page 26), and set
• 122.01 User Power ref to 0 A
Set current limits to low values, for example:
• 130.119 Minimum current
• 130.120 Maximum current
After start, increase slowly the value of parameter
Check the following signals:
• 102.01 DC voltage
• 102.02 ES voltage used
voltage.)
• 102.08 Total current (This signal should be according to
• 102.11 Modulation index %
• 130.101 DDC limit word 1

Parameter settings for DC voltage control mode


After the first start, set the following parameters:
• 123.02 DC voltage ref selection
Set to FB A ref1 or DDCS ctrl
• 123.06 DC voltage ref max
Set to the same level as
controlled, set as 130.114 Maximum ES
• 123.07 DC voltage ref min
Set to the same level as
controlled, set as 130.114 Maximum ES
• 123.09 DC voltage ref ramp up
Use the default value (1000 ms, time from 0 V to nominal DC voltage
voltage)).
• 123.10 DC voltage ref ramp down
Use the default value (1000 ms, time from nominal DC voltage
0 V).
• 123.12 DC voltage ref scale
Use the default value (1.00).
• 123.15 DC voltage ref shape time
Use the default value (0.0 ms, no S-ramp).
• 128.01 DC voltage control select
Usually, set to DC bus voltage
• 128.03 DC voltage error filtering time
Use the default value (0 ms, no filtering).
• 128.08 DC voltage ctrl proportional gain
Use the default value (10.00), and tune if needed.
• 128.09 DC voltage ctrl integration time
Use the default value (20 ms), and tune if needed.
• 128.10 DC voltage control droop
Set to Yes if at least two DC/DC converter modules are controlling the same DC bus voltage.
• 128.11 DC voltage drooping rate
Use the default value (5.0%), and tune if needed.
