In the event of a fault
If an error occurs during the procedure or the pulse inhibit gets active (e.g. due to short-time
undervoltage), the procedure is terminated with controller inhibit without changing the codes for
the motor parameters.
Display and manual adjustment of motor data
In »Engineer« you can have an equivalent circuit diagram with the motor parameters displayed by
clicking on the Further motor data... button on the Application parameters in the dialog level
OverviewMotorMotor:
• The representation of the equivalent circuit diagram depends on the motor control selected
(
).
• The motor stator resistance (
) and motor stator leakage inductance (
) can be
altered directly via the input fields in the equivalent circuit diagram.
• The motor magnetising current (
) is displayed as comparison value to the motor current
(
).
• The motor magnetising current must especially be observed in case of a no-load operation,
both at standstill and with rated speed.
• The motor magnetising current is directly calculated from the rated motor current (
)
and the motor power factor (
).
• The mutual motor inductance can be indirectly adapted via the parameter Lh adjustment
(
) in the range of 50 ... 200 %. The mutual motor inductance evaluated in percent is
shown in
.
• The motor rotor resistance can be indirectly adapted via the parameter Rr adjustment (
in the range of 50 ... 200 %. The motor rotor resistance evaluated in percent is shown in
