EM - 32 Electronic Modules Ver. 0002
EM.4.3.1 SPEED ENABLE, DRIVE ENABLE
Normal operation mode.
1. Activate inputs “Drive Enable” and “Speed Enable”
They may be activated in any order. Before doing so, the "Soft Start" process (smoothly
reaching the power bus voltage) must be over. The torque at the motor will only be
available when Drive_Enable is active and there is voltage at the Power Bus. The
motor speed will be controlled by a velocity command when Speed_Enable
function is active.
Attention: For activating the Speed_Enable function, the system MUST request it in three
different ways: electrical signal at connector X2, variable BV7 -F00203- and variable
DRENA of the PLC when using the Sercos 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 Vdc. If any of them is deactivated, the following will
happen:
