3.12 External Interlock
Systems that may be affected during drive fault conditions should be interlocked with the drive fault output and ready signal.
u
Drive Ready
When the “Drive ready” signal has been set to one of the multi-function contact outputs, that output will close whenever the
drive is ready to accept a Run command or is already running.
The “Drive ready” signal switches off when operation is not possible for a Run command input under the following conditions
regardless of whether a fault exists:
when the power supply is shut off
during a fault
when there is problem with the control power supply
when a parameter setting error makes the drive unable to run even if a Run command has been entered
when a fault such as overvoltage or undervoltage is triggered as soon as the Run command is entered
when the drive is in the Programming mode and will not accept a Run command even when entered
n
Interlock Circuit Example
Two drives running a single application might interlock with the controller using the Drive Ready and Fault output signals as
shown below. Figure 3.49 illustrates how the application would not be able to run if either drive experiences a fault or is
unable to supply a Drive Ready signal.
