CO: Act. filtered frequency
Displays actual inverter output frequency (r0021) excluding slip compensation, resonance damping and frequency limitation.
Act. filtered rotor speed
Displays calculated rotor speed based on inverter output frequency [Hz] x 120 / number of poles.
r0022 [1/min] = r0021[Hz] ⋅ | 60 |
r0313 |
CO: Act. filtered power
Displays motor power (power output at the motor shaft).

r0032 [hp] = 0.75 ⋅ r0032 [kW]
CO: Motor temperature
Displays the measured motor temperature in °C.
CO: Frequency inverter utilization
Displays the frequency inverter utilization as a % referred to the overload. In so doing, the value is calculated using the I2t model.
The I2t actual value relative to the maximum possible I2t value provides the level of utilization.
CO: Energy consumpt. meter [kWh]
Displays electrical energy used by inverter since display was last reset.

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.
