Parameter | Function | Range | Description / Notes |

|
| [Default] |
|
|
| |
P078 | • | Continuous boost (%) | 0 - 250 | Operates continuously over the whole frequency range. | |||
|
|
| [100] | For many applications it is necessary to increase low frequency | |||
|
|
|
| torque. This parameter sets the | |||
|
|
|
| available torque for low frequency operation. 100% setting will | |||
|
|
|
| produce rated motor current at low frequencies. | |||
|
|
|
| WARNING: | If P078 is set too high, overheating of the motor | ||
|
|
|
|
| and/or an overcurrent trip (F002) can occur. |
| |
P079 | • | Starting boost (%) | 0 - 250 | For drives which require a high initial starting torque, it is possible to | |||
|
|
| [0] | set an additional current (added to the setting in P078) during | |||
|
|
|
| ramping. This is only effective during initial start up and until the | |||
|
|
|
| frequency setpoint is reached. | |||
|
|
|
| Note: This increase is in addition to P078, but the total is limited to | |||
|
|
|
| 250%. |

P081 |
| Nominal frequency for motor | 0 - 120.00 |

| Nominal speed for motor (RPM) | 0 - 9999 |

|
|
| |
P083 |
| Nominal current for motor (A) | 0.1 - 99.9 | ‘These parameters are set in the factory and should not be changed | |||
|
|
| [] | under normal circumstances. | |||
P084 |
| Nominal voltage for motor (V) | 0 - 1000 |

P085 |
| Nominal power for motor | 0 - 100.0 |

|
|
| |
P086 | • | Motor current limit (%) | 0 - 250 | The motor current can be limited with this parameter. If the set value |
| ||
is exceeded, the output frequency is reduced until the current falls | |||||||
|
|
| [150] | ||||
|
|
|
| below this limit. During this process, both LEDs will flash (see section | |||
|
|
|
| 3.6). |
|
| |
P087 | Motor PTC enable | 0 - 1 |
|
| [0] |
Change this parameter only when the PTC option is fitted.
0 = Disabled
1 = Motor PTC enabled
Note: If P087 = 1 and the PTC input goes high then the inverter will trip (fault code F004). Note that if the internal PTC gets too hot, the inverter will trip (fault code F005).
P089 • | Stator resistance ( | Ω | ) | 0.01- | Set in the factory. Do not adjust! | |

P091 • | Serial link slave address | 0 - 30 | Up to 31 CombiDrive ® can be connected via the serial link and | |||
|
|
|
| [0] | controlled by a computer or PLC using the USS protocol. This | |
|
|
|
|
| parameter sets a unique address for the inverter. | |
P092 • | Serial link baud rate |
| 3 - 7 | Sets the baud rate of the RS485 serial interface (USS protocol): | ||
|
|
|
| [6] | 3 = | 1200 baud |
|
|
|
|
| 4 = | 2400 baud |
|
|
|
|
| 5 = | 4800 baud |
|
|
|
|
| 6 = | 9600 baud |
|
|
|
|
| 7 = | 19200 baud |
|
|
|
|
| Note: | Some RS232 to RS485 converters are not capable of |
|
|
|
|
|
| baud rates higher than 4800. |
