r0209 | Maximum inverter current |
| Min: | - |
| Datatype: Float | Unit: A | Def: | - |
|
| Max: | - |
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.

Parameter P0210 defines the supply voltage.
Level
3
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
Reducing the value enables controller to cut in earlier and reduce the risk of overvoltage.

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 |
| Min: | - |
| Datatype: U16 | Unit: m | Def: | - |
|
|
| Max: | - |
Level
3
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.
