3. Set the impedance setpoints to be sent and its ramp. The allowed maximum and
minimum values are 1000 and 0.8 Ω. The ramps go from 0 to 1000 Ω /ms. The user
must calculate the appropriate value or resistance to get the desired current.
The converter is controlling channels U and W and both are referred to
channel V. If the current setpoints of phases U and W add up to the limits
of V channel, the equipment will go to alarm. In the supervision tab, the
user can see which is the current and the power flowing through V phase.
4. Set the voltage setpoints to be sent and its ramp. The allowed maximum and
minimum values are 750 and 20V. The ramps go from 0 to 1000V/ms.
All setpoints windows have the actual value right beside them. In this
way, the user can know it without being necessary the supervision tab.
5. Set the resistance value to create a voltage drop. It is configurable for each channel.
The difference between the positive (POS) resistance and the negative (NEG)
resistance is that each one will work depending on the sign of the flowing current.
The maximum and minimum values are 1 and 0Ω.
Please note that it is a virtual resistance. It means that there is any physical
resistance introduced in the equipment.
6. Once all the setpoints are ready, the user must press Send Set Points button and it
will send only the setpoints of the actual control mode (the illuminated part).
For example, if the equipment is in voltage mode, when the voltage setpoints are
ready and the user press Send Set Points, the voltage values are sent whereas the
current, power and impedance values are not sent. Refresh Set Points button will
refresh the setpoints with the actual value of setpoints showed in the actual value
windows (beside the setpoints). But if the equipment is controlling power, for
example, the actual value of power is not being sent to the set point on the left.
- B: The graph explains which is the direction of the current and power according to the
setpoints.
- C: The equipment has its rated values and limits itself, but the user can set another limits
(lower than the factory ones). The factory limits are the followings:
