Motor and motor control
Function
DANGER
Be careful when measuring the electric components in the motor
control. All components have a potential difference of approx. 300 V
in relation to protective earth and neutral.
When the green LED on the motor control card is lit, the compo-
nents carry dangerous voltages.
The motor control lose all voltage about 10-30 seconds after the
voltage has been disconnected and the motor has stopped.
The motor control communicates with the programme unit via a serial two-
wayinterface.Withthehelpofthemotorcontrol,theprogrammeunitcan
