Display readout
Fr
The variable frequency drive shows the present output
frequency in Hertz [Hz].
Io
The variable frequency drive shows the present output
current in Amps [A].
Uo
The variable frequency drive shows the present output
voltage in Volt [V].
Ud
The variable frequency drive shows the intermediate
circuit voltage in Volt [V].
Po
The variable frequency drive shows the calculated out-
put in kilowatt [kW].
notrun
This message is shown if an attempt is made to
change a parameter value while the motor is running.
Stop the motor to change the parameter value.
LCP
This message is shown if an LCP 2 control unit is fitted
and the [QUICK MENU] or [CHANGE DATA] key is
activated. If an LCP 2 control unit is fitted you can only
change parameters with that.
Ha
The variable frequency drive shows the present Hand
mode reference frequency in Herz (Hz).
SC
The variable frequency drive shows scaled output fre-
quency (the present output frequency x parameter
008).
Hand Auto
During normal operation the adjustable frequency
drive is in auto mode, where the reference signal is
given externally, analog or digital via the control ter-
minals. However, in hand mode, it is possible to give
the reference signal locally via the control panel.
On the control terminals, the following control signals
will remain active when hand mode is activated:
• Hand Start (LCP2)
• Off Stop (LCP2)
• Auto Start (LCP2)
• Reset
• Coasting Stop Inverse
• Reset and Coasting Stop Inverse
• Quick Stop Inverse
• Stop Inverse
• Reversing
• DC Braking Inverse
• Set-up Select LSB
• Set-up Select MSB
• Thermistor
• Precise Stop Inverse
• Precise Stop/Start
•Jog
• Stop Command Via Serial Comm.
Switching between Auto Mode and Hand mode:
By activating the [Change Data] key in [Display Mode],
the display will indicate the mode of the adjustable fre-
quency drive.
Scroll up/down in order to switch to hand mode:
When the adjustable frequency drive is in hand mode,
the readout will appear as follows:
and the reference can be changed by using the fol-
lowing keys:
