r0209

Maximum inverter current

P-Group: INVERTER
Displays maximum output current of inverter.
Dependency:
Parameter r0209 depends on the derating which is affected by pulse frequency P1800, ambient
temperature and altitude. The data of deration is given in the OPERATING INSRTRUCTION.
P0210

Supply voltage

CStat: CT
P-Group: INVERTER
Parameter P0210 defines the supply voltage.
Its default value depends upon the type of inverter. If P0210 does not correspond to the supply voltage, then
it must be modified.
When P0210 has been modified, the following thresholds are changed:
Dependency:
Optimizes Vdc controller, which extends the ramp-down time if regenerative energy from motor would
otherwise cause DC link overvoltage trips.
Reducing the value enables controller to cut in earlier and reduce the risk of overvoltage.
Set P1254 ("Auto detect Vdc switch-on levels") = 0. Cut-in levels for Vdc-controller and compound braking
are then derived directly from P0210 (supply voltage).
Vdc_min switch-on level
Vdc_max switch-on level
Compound braking switch-on level
Dynamic braking switch-on level
Note:
- If mains voltage is higher than value entered, automatic deactivation of the Vdc controller may occur to
avoid acceleration of the motor. An alarm will be issued in this case (A0910).
- Default value is depending on inverter type and its rating data.
r0231[2]

Max. cable length

P-Group: INVERTER
Indexed parameter to display maximum allowable cable length between inverter and motor.
Index:
r0231[0] : Max. allowed unscreened cable length
r0231[1] : Max. allowed screened cable length
Notice:
For full EMC compliance, the screened cable must not exceed 25 m in length when an EMC filter is fitted.
