Temperature detection
For motors with temperature detection (KTY83−110) the controller can
consider temperature changes in its motor model. The accuracy and stability
of the vector control are improved considerably.
ƒ Sensor connection:
– X8/5 = −KTY (rt/ws/bl)
– X8/8 = +KTY (br/gr/sw)
)
Note!
You can also use the thermal sensor (KTY) without speed
feedback.
ƒ When monitoring SD6 (C0594) is activated, temperature feedback is
activated at the same time.
ƒ First, activate the temperature feedback and then start the motor
identification to consider the motor temperature.
ƒ In addition, you can activate and parameterise the monitoring
functions OH3 (C0583) and OH7 (C0584).
ƒ The current motor temperature can be displayed via C0063.
Setting integral action component
To initialise the speed controller with a starting torque, the integral action
component of the speed controller can be described via MCTRL−I−SET
(starting value) and MCTRL−I−LOAD (control signal).
Input signal Effect
MCTRL−I−LOAD = HIGH l The speed controller transmits the value at MCTRL−I−SET to its
integral action component
l The P component is switched off
MCTRL−I−LOAD = LOW The speed controller is active
