weak?). Stop the motor.
4. Solutions of the problems
1.1 What dictates the maximal voltage of the drive? Why is it limited?
Maximal voltage voltage is determined by the drive manufacturer and is usually
dictated by the motors ability to dissipate excess thermal energy that comes
from the internal resistance of windings.
Applying excessive voltage can cause the motor to run inefficently, components
to wear out prematurely or cause permanent damage to the motor from excess
heat disspation.
1.2 What parameter sets a mode of the drive operation? What modes
exist?
From the laboratory manual, I found 3 parameters that determine motor
operation modes:
Parameter P036 sets Start Source.
Possible values: 0 Keypad 1 Remote panel
Parameter P037 sets the stop (braking) mode.
Possible values: 0 Ramp 1 Coast 2 DC Brake
Parameter A125 sets the Torque Performance mode.
Possible values: 0 V/Hz, 1 Sensorless vector
1.3 Explain the difference between the drive braking modes?
