Grid/Network Voltage (U2) level [G254]
Grid/Network voltage (U2) level at which specified CosΦ2
is maintained.
Displacement power factor (CosΦ3) At
Voltage level (U3) [G255]
Desired displacement power factor (CosΦ3) at measured
grid/network voltage (U3) level.
Grid/Network Voltage (U3) level [G256]
Grid/Network voltage (U3) level at which specified CosΦ3
is maintained.
Displacement power factor (CosΦ4) At
Voltage level (U4) [G257]
Desired displacement power factor (CosΦ4) at measured
grid/network voltage (U4) level.
Grid/Network Voltage (U4) level [G258]
Grid/Network voltage (U4) level at which specified CosΦ4
is maintained.
Filter Time Constant On Grid/Network
Voltage Measurement [G259]
Grid/Network voltage measurement used for CosΦ (U)
support has a first order filter. Time constant for that first
order filter can be configured here. This is common time
constant for all the voltage levels i.e. U1, U2, U3 and U4.
Lock-In Active Power Level [G25B]
CosΦ (U) mode is turned on if the actual active power of
AFR/AFG is higher than the value set in this menu.
Lock-Out Acvtive Power Level [G25C]
CosΦ (U) mode is turned off if the actual active power of
AFR/AFG is lower than the value set in this menu.
Default: 95%
Range: 0%- 120%
Default: -0.95
Range: -1.00 - 1.00
NOTE:
-ve CosΦ3 value in [G255] indicates the under excited
(Q-absorbed) mode and +ve sign indicates the over-
excited (Q-delivered) mode.
Default: 105%
Range: 0%- 120%
Default: -0.90
Range: -1.00 - 1.00
NOTE:
-ve Cos
Φ4 value in [G257] indicates the under excited
(Q-absorbed) mode and +ve sign indicates the over-
excited (Q-delivered) mode.

NOTE:
Setting 0 (off) in [G25B] turns off the lock-in and lock out
function for Cos
Φ (U).
NOTE:
Hysteresis between lock-in and lock-out is available only
if lock-in is higher than the lock-out value. In that cases,
the difference between lock-in and lock-out acts as a
hysteresis.
