Subfault: 9.6
Description: Maximum model speed exceeded
Response: Output stage inhibit
Cause
Measure
Rotational speed of drive calculated in ELSM
®
control mode too high for motor control.
If possible, minimize the "Speed/position control-
ler sampling cycle", or reduce the speed.
Subfault: 9.8
Description: Flux model error
Response: Output stage inhibit
Cause
Measure
Rotor flux calculated by motor model not plaus-
ible, or calculated internal voltage too small.
– Check configuration data.
– Check motor data.
– Check machine: Idle state or speed too low.
– Check the connection cable between inverter
and motor.
– Contact SEW-EURODRIVE Service.
Subfault: 9.9
Description: Parameter measurement not possible with active motor type
Response: Output stage inhibit
Cause
Measure
Parameter measurement is possible only with
"asynchronous" and "synchronous" motor types.
No magnetic reluctance motors and LSPM mo-
tors.
Select the correct motor type.
Subfault: 9.10
Description: Rotor stall monitoring
Response: Output stage inhibit
Cause
Measure
The current control cannot hold the load torque.
The deviation between stationary setpoint voltage
and actual voltage is too large.
Reduce the load torque (hoist) in the controlled
system.
Subfault: 9.11
Description: Standstill current function
Response: Output stage inhibit
Cause
Measure
With the ELSM
®
method, the standstill current
function is possible only in combination with rotor
position measurement.
– Enable rotor position measurement.
– Check motor data.
