Code 27004: Axis %1, difference safe input %2, NCK %3, drive %4

Parameters: %1 = Axis number %2 = Monitoring input %3 = Interface identifier NCK input %4 = Interface identifier drive input Diagnostics Manual (DAsl), 03/2009 Definitions: A difference has been found on the specified safe input. The state of the specified input signal differed in the two monitoring channels NCK and SIMODRIVE611D during the duration set in $MA_SAFE_MODE_SWITCH_TIME. Monitoring in question (%2): SS/SV = Difference in SGE "Deselection of safe operating stop/Safe velocity" SS = Difference in SGE "Safe operating stop" SV = Difference in SGE "Selection safe velocity" SP = Difference in SGE "Selection safe limit position" SVOVR = Difference in SGEs "Selection SG correction" Interface identifier NCK input (%3): DMP<drv><mod><bit>=<value> <drv> = Drive number of terminal block (1...31) <mod> = Submodule number (1...8) <bit> = Terminal number (1...16) <value> = Value of NCK SGE (0,1) SPL For when the SGE is parameterized at the SPL interface. <io> = Parameterizable system vari able range (01=$A_INSID, 02=$A_INSED) <dword> = System variable double word (1,2) <bit> = Bit number in system variable double word (1...32) <value> = Value of NCK SGE (0,1) Onboard input For when the SGE is parameterized at an onboard input. <bit> = Input number = 01...04 <value> = Value of NCK SGE = 0,1 Interface identifier drive input (%4): DBX<byte><bit>=<value > <byte> = Byte number in axial DB (22, 23, 32, 33) <bit> = Bit number in byte (0...7) <value> = Value of drive SGE (0,1) This alarm can be hidden by setting MD $MN_SAFE_DIAGNOSIS_MASK, bit 0 = 0. Reaction: Alarm display. Remedy: Check settings for safe input signals (NCK I/Os, PLC DB parameters). Program Continuation: Clear alarm with the RESET key. Restart part program
