Connecting Enable Outputs
EDC User's Manual
Chapter:
2. Installation
Section:
Connecting Outputs
Read the above section of the
EDC User’s Manual
before connecting
enable outputs.
The enable output for an axis should be used if the servovalve, valve driver
card, or servo drive has an enable input. The enable output functions to
prevent movement of the axis during a Fault or Excess Error condition.
Check that the enable input of the servovalve, valve driver card, or servo
drive is compatible with the EDC Controller enable output. The EDC
Controller enable is factory configured as ON=low. To set it for ON=high,
jumper changes are necessary.
Before changing jumpers or making connections, make sure that power
is removed from the Controller.
Before making connections, be sure that power is removed from the
actuator.
If the servovalve, valve driver card, or servo drive has no enable input, you
must make other provisions to ensure that actuator will not “run away”
during a Fault or Excess Error condition. You can best do this by
installing the Model 475.71c Command Enable module.
Connect the enable outputs for Axis X (and Y, if Y is used). Do not apply
power to the actuator at this time.
