FB error: MC_Power. State machine implemented within CANopen drive doesn't react as expected.

Description

When a CANopen drive is switched on, the drive controller passes through several states. The correct sequence of states is monitored in the function block MC_Power. The error is output because the combination of previous and current states may not occur during the power-on sequence. The sequence of states during drive power-on is:

  1. GC_CO_SWITCH_ON_DISABLED_1 or GC_CO_SWITCH_ON_DISABLED_2
  2. GC_CO_READY_TO_SWITCH_ON
  3. GC_CO_SWITCHED_ON
  4. GC_CO_OPERATION_ENABLED.

Response

Class

-

As long as the drive sends this status information, the function block sets the output "Error" TRUE and displays the error code at output "ErrorID".

Its subsequent response depends on the values assigned to inputs "Enable", "Enable_Positive" and "Enable_Negative" and the status data sent by the drive.

Solution

Class

-

Check why the power-on sequence was interrupted. Once the problem has been solved, you can command the MC_Power again.
