*:conf-P Description
r303 Vd(act)
Actual unsmoothed DC-link voltage value
12FHex
Analog output: 100 % with code number (PWE) = 4 x P071
Type=I2; PKW: 1HEX=1 V
P308 Sampling Time
Basic sampling time T0.
134Hex
Setting instructions:
• When the sampling time is reduced, the available
computing time should be checked via parameter r725 in
the "Run" state. At least 5 % of the available computing
time should always be left in reserve to avoid any delayed
(slow) execution of operator inputs.
If fault F042 "Computing time" occurs, the sampling time
•
setting must be increased again.
Type=O2; PKW: 1HEX=0.1 ms
P325 MC switch-on del
Delay time for closing (energizing) the main contactor.
145Hex
By delaying energization of the main contactor, it is possible to
charge the DC link up to the line voltage peak value via the
precharging resistors. This measure will be necessary if the
external DC-link capacitance connected to the AFE is
significantly higher than that of the AFE.
Type=O2; PKW: 1HEX=0.1 s
P326 Max.pre-chrg. t.
Maximum precharging time
146Hex
If the DC link is not successfully precharged within this period,
fault message Precharging (F002) or, if the line voltage is too
low, fault message Line Voltage (F004) is activated.
RDS(2) parameter
Type=O2; PKW: 1HEX=0.1 s
P329 MCInvEnableDel
Delay between activation of the main contactor and enabling
149Hex of the inverter.
By increasing this time, it is possible to ensure that the DC link
is charged up completely to the peak value of the mains
voltage. This is necessary if the external DC link capacity
connected to the AFE is considerably greater than that of the
AFE. The set time should always be at least 100 ms greater
than the time that the main contactor needs to close the
contacts.
Type=O2; PKW: 1HEX=0.o1 s
