Danger
The EMERGENCY STOP functions must always be functioning when
commissioning the drive. The relevant safety regulations must be
observed to exclude danger for man and machine.
When optimizing the motor data, motor movements are initiated, which
can reach the maximum motor speed.
The use of unlisted induction motors with "SIMODRIVE 611 universal"
is supported with the motor data optimization.
Often, the commissioning engineer only knows the rating plate data
(manufacturer's data according to DIN VDE 0530, Part 1) of the motor.
The "Calculate equivalent circuit diagram data" function can be used to
calculate other motor data.
The result of the calculation is merely an approximate estimate. The
motor data optimization is used to improve the result.
When optimizing the motor data, voltage, current and speed setpoint
patterns are output to the motor, and information regarding the equiva-
lent circuit diagram data is taken from the motor response.
The following prerequisites are necessary when commissioning the
drive system:
S
Pulses, controller, and ramp–function generator must be enabled.
S
Motor data optimization is possible in the MSD and IM modes.
S
For MSD operation, it is not necessary to determine the moment of
inertia.
