r0064

CO: Dev. frequency controller

Min: -

Datatype: Float Unit:

Hz

Def:

-

P-Group: CONTROL

Max: -

Displays actual deviation of speed controller.

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: -

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: -

Datatype: Float Unit:

Hz

Def:

-

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.

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

Min

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: -

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.

Index:

r0069[0] : U_phase
r0069[1] : V_phase
r0069[2] : W_phase
r0069[3] : Offset U_phase
r0069[4] : Offset V_phase
r0069[5] : Offset W_phase
