Other functions

The "Prog. Out" contact (pins 8 and 9) is a user programmable output by
means of an internal parameter of the drive. See parameter OP5 in chapter
13 of the "man_dds_soft.pdf" manual.

Normal operating mode
1. Activate the Drive Enable and Speed Enable inputs (24 V DC) in the
desired order. Before activating, the Soft Start process (smoothly reaching
the power bus voltage) must be over. The motor will have torque only
when Drive Enable is active and there is voltage at the power bus. The
motor speed will be controlled with a command when the Speed Enable
function is active.
INFORMATION. Activating the Drive Enable function requires to be
requested by the system in three different ways. They are: Electrical signal
i
at connector X2, variable BV7 (F00203), and variable DRENA of the PLC
when using the SERCOS-II or CAN interface. It could be deactivated
through any of them.
2. The motor will respond to all analog command variations only while
both inputs (Drive Enable and Speed Enable) are at +24 V DC. If any of
them is deactivated, the following will happen. See the operation modes
in figure F. H3/115.
Deactivation of the Drive Enable input
The Drive Enable input lets the current circulate through the motor stator
windings. When it is powered with 24 V DC the current is enabled and the drive
can work.
If the Drive Enable input drops to 0 V DC (no voltage), the power circuit is off
and the motor will have not torque, hence not being governed and will turn
freely until it stops by friction.
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.
