SC-OBS
Communication
failure with other
devices
• A keypad has lost the communication connection to the
inverter.
• The communication connection has been disconnected
in the master-slave network.
• Check the addresses of all inverters in the network.

Switching fre-
quency decreased
The PWM frequency was automatically decreased due to
the heat sink temperature.

Speed error
(
P6-07
)
The difference between the actual speed and setpoint
speed is larger than the percentage value set in
P6-07
.
This error applies only to vector control or control with en-
coder feedback. Set a higher value in
P6-07
.
If you wish to deactivate speed monitoring, set
P6-07
to
100%.

STO circuit fault
The safety relay must not transmit test pulses.
Check the voltage source.
STO+ at terminal 12 must be > 18 V.
StoP
The inverter is not
enabled
Activate the enable. Make sure that the enable is
switched on after the STO for the hoist function.
