SPEED ENABLE AND DRIVE ENABLE
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. Only via connector X2 is certified. See chapter
SAFETY.
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. H3/60.
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.
