Parameter Description

Issue 01/06

r0064

CO: Dev. frequency controller

 

Min:

-

 

Datatype: Float

Unit: Hz

Def:

-

 

P-Group: CONTROL

 

Max:

-

Displays actual deviation of speed controller.

Level

3

This value is calculated from the frequency setpoint (r0062) and the actual frequency (r0063).

Dependency:

Applies when vector control is selected in P1300 (control mode); otherwise, the display shows the value zero.

r0065

CO: Slip frequency

 

Min:

-

 

Datatype: Float

Unit: %

Def:

-

 

P-Group: CONTROL

 

Max:

-

Level

3

Displays slip frequency of motor in [%] relative to the rated motor frequency (P0310).

Details:

For V/f control, see also P1335 (slip compensation).

r0066

CO: Act. output frequency

 

Min:

-

Level

 

Datatype: Float

Unit: Hz

Def:

-

3

 

 

 

P-Group: CONTROL

 

Max:

-

 

Displays actual output frequency.

Note:

The output frequency is limited by the values entered in P1080 (min. frequency) and P1082 (max. frequency).

r0067

CO: Act. output current limit

 

Min:

-

 

Datatype: Float

Unit: A

Def:

-

 

P-Group: CONTROL

 

Max:

-

Displays valid maximum output current of inverter.

Level

3

Parameter r0067 is influenced/determined by the following factors:

-Rated motor current P0305

-Motor overload factor P0640

-Motor protection in dependency of P0610

-r0067 is less than or equal to maximum inverter current r0209

-Inverter protection in dependency of P0290

Motor protection

Min

r0209

Inverter protection

r0067

Note:

A reduction of r0067 may indicate an inverter overload or a motor overload.

r0068

CO: Output current

 

Min:

-

 

Datatype: Float

Unit: A

Def:

-

 

P-Group: CONTROL

 

Max:

-

Level

3

Displays unfiltered [rms] value of motor current [A].

Note:

This is used for the process control (contrary to the smoothed output current r0027, that is used for display).

r0069[6]

CO: Act. phase currents

 

Min:

-

 

Datatype: Float

Unit: A

Def:

-

 

P-Group: CONTROL

 

Max:

-

Displays phase currents.
