r0021 CO: Act. filtered frequency
Displays actual inverter output frequency (r0021) excluding slip compensation, resonance
damping and frequency limitation.
r0022 Act. filtered rotor speed
Displays calculated rotor speed based on inverter output frequency [Hz] x 120 / number of
poles.

r0035 CO: Motor temperature
Displays the measured motor temperature in °C.
r0036 CO: Frequency inverter utilization
Displays the frequency inverter utilization as a % referred to the overload. In so doing, the
value is calculated using the I
2 t model.
The I 2 t actual value relative to the maximum possible I 2 t value provides the level of
utilization.
r0039 CO: Energy consumpt. meter [kWh]
Displays electrical energy used by inverter since display was last reset.

r0052 CO/BO: Act. status word 1
Displays the first active status word (ZSW) of the frequency inverter (bit format) and can be
used to diagnose the inverter status.
