P077

 

Control mode

0 - 2

 

Controls the relationship between the speed of the motor and the

 

 

 

[1]

 

voltage supplied by the inverter. One of two modes can be selected:

 

 

 

 

 

 

0/1 = Linear voltage/frequency

 

 

 

 

 

 

Use this curve for synchronous motors or motors

 

 

 

 

 

 

connected in parallel.

 

 

 

 

 

 

2 = Quadratic voltage/frequency relationship

 

 

 

 

 

 

This is suitable for centrifugal pumps and fans.

fN (P081)

P078 ∙ Continuous boost (%)

0 - 250

 

[100]

Operates continuously over the whole frequency range.

For many applications it is necessary to increase low frequency torque. This parameter sets the start-up voltage at 0 Hz to adjust 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.

 

 

 

 

 

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.

 

 

 

 

 

 

Nominal frequency for motor (Hz)

0 - 400.00

 

 

 

 

 

[50.00]

 

 

 

 

Nominal speed for motor (RPM)

0 - 9999

 

 

 

 

 

[

]

These parameters must be set for the motor used.

Nominal current for motor (A)

0.1 - 99.9

Read the specifications on the motor’s rating plate (see Figure 10 in

 

 

[

]

section 3.2.1).

 

Nominal voltage for motor (V)

0 - 1000

Note: The inverter’s default setting vary according to the power rating.

 

 

[

]

 

 

 

Nominal power for motor (kW/hp)

0 - 100.0

 

 

 

 

 

[

]

 

 

 

Stator resistance (Ω)

0.01-100.00

The stator resistance of the motor should be entered in this parameter.

 

[

]

The value entered should be the resistance between any two phases

 

 

 

 

with the motor connected. The measurement should be made at the

 

 

 

 

inverter output terminals with power off.

 

 

 

 

Note:

If the value of P089 is too high then an overcurrent trip

 

 

 

 

 

(F002) may occur.

 

 

 

 

 

Serial link slave address

0 - 30

 

Up to 31 inverters can be connected via the serial link and controlled

 

[0]

 

by a computer or PLC using the USS protocol. This parameter sets a

 

 

 

 

unique address for the inverter.
