4.8.4 Switching in the motor cable
CAUTION! Damage to the device due to switching in the motor cable!
Carelessness can cause damage to the device
Switching in the motor cable must take place with the power switched off and the power stage
disabled, as otherwise problems such as burned contactor contacts or power stage damage
may occur.
To interrupt the supply of power to the servomotor, the safety function STO is available,
see Chapter 7.1.
4.8.5 Electronic overload protection for the motor
The motor protection function acquires the motor frequency, the motor current and other
parameters. Depending on these parameters shown in the device help and the motor
rated motor current, the electronic motor protection triggers the protection function if
there is an overload.
y As I
2
T monitoring with programmable rated motor current, the permissible
multiple of the rated motor current, the trigger time and the speed-dependency
of the rated motor current. For explanations, see device help.
y The I
2
T integrator acts as a thermal memory for the system.
The thermal memory is retained while the motor is at standstill if the device is
switched on.
y The devices do not retain the thermal memory if switched off, i.e. the electronic
motor overload protection is reset by switching off and on again the power
supply.
The electronic motor overload protection can be increased by using a motor temperature
sensor.
