To be able to activate the final stage of the motor controller, the digital inputs final stage
enable and controller enable must be set: The final stage enable works directly on the
control signals of the power transistors and could also interrupt them in case of a
defective microprocessor. Removal of the final stage enable with a running motor thus
causes the motor to spin out unbraked or makes it stoppable only with the holding brake
that might be available. The controller enable is processed by the microcontroller of the
motor controller. After removal of this signal, the motor controller reacts differently,
depending on the operation mode:
-
Positioning mode and velocity-controlled mode
After removal of the signal, the motor is braked following a defined braking ramp.
The final stage is not shut off until the motor rotation speed is below 10 min
-1
and the
holding brake, if present, has been applied.
-
Torque-controlled operation
The final stage is shut off immediately after removal of the signal. Simultaneously, the
holding brake, if present, is applied. The motor thus spins out or is stopped only by the
holding brake, if present.
Warning
Potentially fatal voltage!
The two signals do not ensure that current is shut off to the motor.
During operation of the motor controller via the CAN bus, the two digital inputs
final stage
enable
and
controller enable
are both set to 24 V, and the enable is controlled via the
CAN bus. For this, the object

(

) must be set to two. For safety
reasons, this takes place automatically on activation of CANopen (also after a reset of the
motor controller).
