P2xx Controller parameters
P29x Regenerative power supply
The DC link voltage of the supply and regenerative unit is adjusted via voltage control
with lower-level current control.
P290 Minimum
voltage
Setting range: 620 V – 780 V
In the supply and regenerative unit, the level of the controlled DC link voltage depends
on the line voltage level. The DC link voltage is carried along with the line voltage auto-
matically. The minimum voltage for the DC link is 620 V.
For low line voltages, the minimum voltage can be increased
Automatic assignment (no parameter setting required):
Recommendation: Do not change the factory setting.
P291 P gain volt-
age controller
Setting range: 0.000 – 1.775 – 100.000 A/V
The DC link voltage of the supply and regenerative unit is adjusted via voltage control
with lower-level current control.
Recommended settings when connecting:
• Only units of sizes 0 to 6 (number of units is not relevant): 0.7
• One unit of size 7 (and smaller sizes in addition, if required): 1.775
• two units of size 7 (and smaller sizes in addition, if required): 2.9
P292 Integral time
voltage controller
Setting range: 0.00 – 30.00 – 10000.00 ms
Recommendation: Do not change the factory setting.
P293 P gain cur-
rent control
Setting range for MDR61B2500: 0.000 – 0.925 – 100.000 V/A
Setting range for MDR61B1600: 0.000 – 1.450 – 100.000 V/A
The current controller is adapted to the choke inductances integrated in the regenerative
power supply.
Recommendation: Do not change the factory setting.
It might be necessary to adjust the current controller to poor supply system conditions
with high impedance.
