6.2 Function test
Caution !
Apply armature voltage only when excitation voltage is
applied!
When the voltage is applied without an excitation voltage
being applied to the motor, the motor may be destroyed
due to overspeed, i.e. the motor speed may rise until the
rotor is destroyed.
¯
Commission the drives and check all
individual functions, such as
-- torque behaviour and current
consumption
-- braking of the attached brake
-- output signal of the feedback system
¯
in case of malfunctions or interferences:
trouble--shooting according to chapter 6.4.
