Parameter Description
Description of input parameters:
Parameter
Data Type
Meaning
RESET
BOOL
Rising input starts reset process. High input inhibits any subroutine from being initiated. Falling input has no effect, except to clear Q.
EN_WDOG
BOOL
Enable watchdog timer. High enables the watchdog timer (WDT). Low disables the WDT. A transition from High to Low stops the WDT. The motion controller will interpret this as a WDT fault and will stop and disable the drive.

Q
BOOL
True when reset process is complete.
OK
BOOL
Low during the reset process. High when the motion controller reports the correct revolution number.
Example
When Reset is turned on, all MMFStart blocks are reset. When WDT_ON is Low, the watchdog function is disabled. When WDT_ON turns on, the watchdog between the PLC and SERCOScontroller interprets this as a watchdog fault, and it stops and disables the drives.
