Description
(Visible when user lock is open)
Selects the actions or functionalities to be prevented by the
user lock. Note that the changes made take effect only
when the user lock is closed. See parameter
code.
Note: We recommend you select all the actions and
functionalities unless otherwise required by the application.

Selection of actions to be prevented by user lock.
DC/DC converter control settings.
Selects the mode for the offset calibration of the current
transducer. For the best possible performance and accuracy
of the energy storage voltage estimation, the current
transducer offsets should be calibrated at least once during
the start-up of the DC/DC converter.
As the DC bus voltage can in some situations drop to the
energy storage voltage level, current may flow from the
energy storage to the DC bus via the freewheeling diodes
inside the DC/DC converter despite of it being in a stopped
state. In this situation the offset calibration, if enabled
always when stopped, can fail and give wrong results. In
that case it is recommended to do the calibration only once
during commissioning when the DC bus voltage is higher
than the energy storage voltage.
Note: Do not enable the calibration if the DC bus voltage is
at the same level or lower than the energy storage voltage.
If the DC bus voltage cannot be increased, then disconnect
the energy storage from the DC/DC converter before doing
the calibration.
Current offset calibration is disabled.
