IDN 128 (S-0-0128) Procedure: Communication Phase 4 Transition Check

Ensures that the drive is ready to switch from CP3 to CP4. The master must successfully execute this procedure prior to switching from CP3 to CP4.

If the procedure fails, IDN 22 will contain a list of IDNs that the drive considers invalid.

If any of the macros have been changed in CP2 or CP3, the drive will re-compile the macro program and perform a warm start, which may take up to 3 minutes.

During the warm start, the LED on the front panel of the drive add with the three dots will flashing. During the warm start IDN 182 Bit 1 is set, it will clear after the warm start.

Alternatively, the serial interface may be used to save all values and reset the drive before the CP4 transition check procedure is executed. (For an explanation of the macros, please consult our applications department.)
