 Situation 2
The torque is kept active by braking the motor. When it stops, variable
SV5 (S00331) is activated. The motor does not stop in a time period set
by parameter GP3 (F00702). The motor stops when its kinetic energy
runs out.
See the internal parameter GP3 (F00702) and the internal variable SV5
(S00331) in chapter 13 of the “man_dds_soft.pdf” manual that is supplied
with this one.

WARNING. In case of mains failure, the control circuit and its signals
must maintain their 24 V DC while the motors are braking.
In the case of the compact drive, the 24 V DC at pins 1 and 2 of connec-
tor X2 meet this requirement and are appropriate for managing the con-
trol signals.
