Parameter

Level

14-IOUT - Motor Output Current

L1*

This display indicates computed output current in amperes. The accuracy of this display is ±10% of inverter
rating (03-IRAT).

15-LOAD - Drive Load

L1*

This display indicates the real part of the motor current by multiplying the computed output current by motor
power factor and comparing it to the inverter's capacity. This indication is positive in the motoring mode,
negative in the regenerative mode of operation. The accuracy is ±10% of full scale.

16-TORQ - Load Torque

L1*

This display shows the torque reduction experienced when operating in the constant power or field
weakened condition, when operating above 53-FKNEE. The accuracy is ±10% of full scale.

17-TEMP - Inverter Temperature

L1*

This display indicates the inverter's operating temperature in °C. The accuracy is ±2°C.

18-TIME1 - Total Run Time

L2*

This display is an indication of the total time the inverter is in the run mode of operation. It has a range of 0-
65000 hr. and is not resettable. Note: Frequent line starting operation of the inverter may result in the
recording of erroneous times in this parameter.

19-TIME2 - Total Operating Time

L2*

This display indicates the total time that power has been applied to the inverter, up to 65,000 hrs. It does not
reset when power is removed and re-applied.

1A-FOUT2 - Motor Stator Frequency

In order for the inverter to provide the motor performance desired in many applications, it is necessary for
the inverter to make changes to the motor frequency independent of the speed setpoint. For instance, when
slip compensation is active, the motor frequency is increased when the motor’s load increases. Parameter
1A allows actual motor frequency to be monitored during operation.

1B-FLUX - Magnetizing Current

This display indicates the amount of magnetizing current that is present to the motor. The displayed
percentage is a calculated factor based on a pre-determined motor model. When using Volts/Hertz mode,
the percentage is based on bus current measurements and torque boost settings. In Vector mode, the
percentage is the inverter’s regulated magnetizing current levels. Parameter 1B can be monitored while the
inverter is in operation.

21-MODE - Input Mode

21-MODE defines the operating functions that are active from the Keypad, the Terminal Strip, and the SIO
Serial Link in both the LOCal and REMote operating modes. Also the mode transfer mechanism is defined
by your selection at this parameter. Proper setting of this parameter is the first step in customizing the
inverter to your application. The following table defines all the combinations available. Other selections for
21-MODE are discussed in Section 5 and in option manuals where their use is fully documented.

Notes:

1. Under LOCal operation, when control is specified as keypad, the active torque limit reference is the

preset values at parameters 61 thru 64 as if parameter 27-TLSEL were set to a code "3". In all other
cases, the drive obeys the setting of parameter 27 directly.

2. Enables or disables the REV key on the keypad.
3. When "Terminals" specified as a speed reference, the programming of parameter 24-FSEL actually

controls the active speed reference.

4. In REM operation, terminals PS1, PS2, PS3 and ART are active. All will (except PS3 in modes greater

than 20) perform their previously defined function (see Section 2.8).

5. Entering the JOG mode from the keypad will override any active presets.

If any questions arise, please don't hesitate to contact an Electrical Applications Engineer at the factory for
clarification before proceeding. See Section 6 for terminal strip connection details.
