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.
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.
r0054
CO/BO: Control word 1
Displays the first control word (STW) of the frequency inverter and can be used to display
the active commands.
r0063
CO: Actual frequency
Displays the actual frequency in Hz.

CO: Selected frequency setpoint
Displays the selected frequency setpoint.
The following frequency setpoints are displayed:
r1078 total setpoint (HSW + ZUSW)
P1058 JOG frequency, clockwise
P1059 JOG frequency, counter-clockwise.
r1114
CO: Freq. setpoint after dir. ctrl.
Displays the setpoint (reference) frequency in Hz after the function block to reverse the
direction of rotation.
r1170
CO: : Frequency setpoint after RFG
Displays the total frequency setpoint (reference value) in Hz after the ramp-function
generator.
