Danger to life as a result of unexpected motor movement for the friction characteristic plot

When the friction characteristic is plotted, the drive can cause the motor to move. As a

result, the motor may reach maximum speed.

For this reason, entering the area around the drive when it is in this condition can cause

death, severe injury or material damage.

• Observe the general safety instructions.

• Ensure that the EMERGENCY STOP functions are always fully functional.
