Deactivation of the Speed Enable input
When the Speed Enable input is set to 0 V DC, the internal velocity command
follows the stop ramp set by parameter and:
 Situation 1 . The torque is kept active by braking the motor. When it stops,
variable SV5 (S00331) is activated. The motor has stopped in a time period
shorter than the one indicated by parameter GP3 (F00702). The torque
is canceled and the rotor is free.
 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 also 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.

Operating modes of functions Drive Enable and Speed Enable.
NOTE. Also see in chapter 2 ( X2 connector , pin 5 on PS power supplies),
( X2 connector , pin 5 on XPS power supplies) or ( X6 connector , pin 5 on
RPS power supplies) corresponding to the System Speed Enable input
and its effect on the Speed Enable inputs of modular drives.

WARNING. AXD/SPD drives (see EC DECLARATION OF CONFORMITY
section) have the Drive Enable input as one channel of STO ( S afe T orque
O FF) safety function (PL d or SIL 2). Main contactor - KM1 may be used for
another channel. See chapter 9. FUNCTIONAL SAFETY in this manual.
WARNING. In case of mains failure, the control circuit and its signals must
maintain their 24 V DC while the motors are braking.
On modular drives, the 24 V DC needed to activate the Drive Enable must
be obtained from a power supply that maintains its rated value during that
period of time. The PS-25B4 power supply, the APS-24 auxiliary power
supply and the regenerative XPS and RPS power supplies meet this
condition.
