Deactivation of the Speed Enable input
When the Speed Enable input is set to 0 V DC, the internal velocity com-
mand 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 en-
ergy 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 sup-
plied with this one.

Operating modes of functions Drive Enable and Speed Enable.
NOTE.
Also see in chapter 2 (
, pin 5 on PS power
supplies), (
, pin 5 on XPS power supplies) or (
, 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
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
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 sup-
ply and the regenerative XPS and RPS power supplies meet this condition.
