4.6.2 Stop Category 1
Stop Category 1 4- ][Funktion_Stopp_1
Stopping the motor in accordance with Category 1 is performed by re-
moval of power and controlled, electronic braking (STOPMODE and
ACTFAULT parameters set to “1”). The 24 V supply voltage to the servo
amplifier must be maintained.
 The drive is braked in a controlled manner as it comes to a stop (dis-
able). If the speed VEL0 (see timing diagram in the section entitled
"Switch on/switch off behaviour") drops below the set value, the hold-
ing brake is applied and the inverted rectifier is shut down.
The mains supply and the holding brake are galvanically isolated after
the two periods set separately on the timers have elapsed.

NOTICE
If there is an internal fault on the servo amplifier, the motor is for-
cibly braked once K20 drops out. Make sure that the machine
cannot be damaged by abrupt braking. Frequent forced braking
using the holding brake built into the motor can damage the
brake.
