Diagnostic parameters

r0021 CO: Act. filtered frequency
Displays actual inverter output frequency (r0021) excluding slip compensation, resonance
damping and frequency limitation.
Act. filtered rotor speed
r0022
Displays calculated rotor speed based on inverter output frequency [Hz] x 120 / number of
poles.
r0022 [1/min]
CO: Act. filtered power
r0032
Displays motor power (power output at the motor shaft).
Motor
r0035 CO: Motor temperature
Displays the measured motor temperature in °C.
CO: Frequency inverter utilization
r0036
Displays the frequency inverter utilization as a % referred to the overload. In so doing, the
value is calculated using the I
2
The I t actual value relative to the maximum possible I
utilization.
CO: Energy consumpt. meter [kWh]
r0039
Displays electrical energy used by inverter since display was last reset.
