7.4 Table of possible reasons for the operating status "Switch-on block"
The following table summarises the messages which are generated if the frequency inverter cannot be
enabled, although no fault is present.

Group Details in
P700 [-03]
I000 0.1 Volt blocked by IO
"Voltage blocked by IO" With the function "Block voltage" the parameterised input
(P420 / P480) is set to Low
Set input to "High"
Check signal cable (broken cable)
0.2 Quick stop by IO
With the function "Quick stop" the parameterised input
(P420 / P480) is set to Low
Set input to "High"
Check signal cable (broken cable)
0.3 Volt blocked by bus
"Voltage blocked by bus"
With bus operation (P509): Control word Bit 1 "Low"
0.4 Quick stop by bus With bus operation (P509): Control word Bit 2 "Low"
0.5 Enable at start Enable signal (control word, Dig I/O or Bus I/O) was already
present during the initialisation phase (after mains "ON" or
control voltage "ON").
Only give enable signal after completion of initialisation (i.e.
when the FI is on standby)
Activation of "Automatic start" (P428)
I006 6.0 Charging error Charging relay not actuated, because
Mains / link voltage too low
Mains voltage failure
Evacuation run activated (Parameter (P420) / (P480))
I011 11.0 Analog Stop If an analog input of the frequency inverter or a connected
I/O extension is configured to detect cable breaks (2-10V
signal or 4-20mA signal), the frequency inverter switches to
the status "Not ready for switch-on" if the analog signal
undershoots the value 1V or 2mA
This also occurs if the relevant analog input is
parameterised to function "0" ("no function").
I014 14.4 Abs encoder error
"Absolute encoder error"
Absolute encoder not ready
I018 18.0 STO active Safe Stop function has been triggered (See BU0230)
