6 Operation

IL•1F CANopen DS301

6.3.3Resetting faults

If an error occurs during operation, the product switches to operating state 7 "Quick Stop" or operating state 9 "Fault", depending on the type of error.

After having remedied the cause of the fault, you can reset the error state with a Fault Reset ("0 -> 1" edge in drivectrl, bit 3).

If the product was originally in operating state 7, it will switch to operating state 6 after the "Fault Reset".

If the product was originally in operating state 9, it will switch to operating state 4 after the "Fault Reset". You then have to transmit a "0 -> 1" edge in drivectrl, bit 1 "Enable", in order to enable the power stage.

Table 6.3 Disabling the power stage

Note: In this example, the master deletes the Bit 1"Enable" during the "Fault Reset" in order to implicitly effect a "0 -> 1" edge in Bit 1. This switches the product back to operating state 6.
