Parameter List/Record A-7
Parameter 50 “Trend 1 Input” to Parameter 104 “Final Vel Ref”
Parameter 51 “Trend 2 Input” to Parameter 106 “Velocity Fdbk”
The sample period for the trend files will be programmed to 10 secs per data
point. The thermal time constant of most motors is quite large, the operating
parameters will be captured for 16 minutes prior to the occurrence of the
fault. The trigger will be programmed to occur when the fault occurs, the
fault will be reported in Parameter 101 “Drive Fault” bit 5. All 100 data
samples will be taken prior to the trigger. The necessary set-up parameter
values for Trend File 1 Are:
Parameter 904“Trend Logic Val” = 00000000000100000 (bit sel)
Parameter 910 “Tr1 Opnd Param X” = 104 (test operand)
Parameter 911 “Tr1 Opnd Param Y” = 904 (constant operand)
Parameter 912 “Tr1 Operator” =.EQ. (operator for bit 5)
Parameter 913 “Tr1 Sample Rate” = 10 (sample rate in sec)
Parameter 914 “Tr1 Post Samples” = 0 (# samples after trig)
Parameter 915 “Tr1 Mult Trigger” = OFF (single shot)
Parameter 916 “Tr1 Enable” = ON (enable trend)
