r0067 CO: Actual output
current limit [A]
- - - P2002 - Float 3
Displays valid maximum output current of inverter.
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
Note: A reduction of r0067 may indicate an inverter overload or a motor overload.
r0068 CO: Output current [A] - - - P2002 - Float 3
Displays unfiltered [rms] value of motor current. This value is available filtered (r0027) and unfiltered
(r0068).
Note: Used for process control purposes (in contrast to r0027, which is filtered).
r0069[0...5] CO: Actual phase
currents [A]
- - - P2002 - Float 4
Displays measured phase currents.
Index: [0] U_Phase / Emitter1/
[1] Dclink / Emitter2
[2] Dclink
[3] Offset U_phase / Emitter
[4] Offset dclink
[5] Not used
r0070 CO: Actual DC-link
voltage [V]
- - - - - Float 3
Displays DC-link voltage. This value is available filtered (r0026) and unfiltered (r0070).
Note: Used for process control purposes (in contrast to r0026 (actual DC-link voltage), which is filtered).
r0071 CO: Maximum output
voltage [V]
- - - - - Float 3
Displays maximum output voltage.
Dependency: Actual maximum output voltage depends on the actual input supply voltage.
r0072 CO: Actual output
voltage [V]
- - - - - Float 3
Displays output voltage. This value is available filtered (r0025) and unfiltered (r0072).
r0074 CO: Actual modulation
[%]
- - - PERCEN
T
- Float 4
Displays actual modulation index. The modulation index is defined as ratio between the magnitude of the
fundamental component in the inverter phase output voltage and half of the DC-link voltage.
r0078 CO: Actual current Isq
[A]
- - - P2002 - Float 3
Displays component of torque generating current. This value is available filtered (r0030) and unfiltered
(r0078).
r0080 CO: Actual torque [Nm] - - - - - Float 4
Displays actual torque. This value is available filtered (r0031) and unfiltered (r0080).
r0084 CO: Actual air gap flux
[%]
- - - PERCEN
T
- Float 4
Displays air gap flux relative to the rated motor flux.
