Unidrive Classic Option Module Trip Codes<\/h2>\n

On Unidrive<\/a> Classics, when a UD7x Unidrive option module error trip occurs,
\nthe display will show the trip code as “tr__”. The trip number
\ncan also be read in Unidrive parameter #10.20 or UD70
\nvirtual parameter #88.01, and the line number where the trip
\noccurs in parameter #17.03, though only if the program was
\ncompiled with debugging information.<\/p>\n

When an error occurs in the UD70, the DPL program will
\nimmediately stop. Also, depending on the cause of the trip
\nand the setting of the Trip enable parameters, the Unidrive will
\ntrip on the “tr__” code. Optionally, an ERROR task may have
\nbeen defined which would be executed whenever a run-time
\nerror occurs. MRO Electric and Supply maintains a comprehensive stock of new and used\u00a0 Control Techniques Unidrive<\/a>\u00a0and Control Techniques Unidrive Classic SP<\/a> parts. If you need a replacement part, please call 800-691-8511 or email sales@mroelectric.com<\/a>.<\/strong><\/p>\n

Code Description Action<\/strong>
\n40 Unknown error Always trips
\n41 Parameter does not exist Trips if #17.14=1
\n42 Parameter read only Trips if #17.14=1
\n43 Parameter write only Trips if #17.14=1
\n44 Parameter value over range Trips if #17.14=1and #17.17=1
\n45 Virtual access failed – e.g. IOLink not running Trips if #17.14=1 (access)and
\n#17.15=1* (all time)
\n46 Stack Overflow Always trips
\n47 Internal error Always trips
\n48 Internal error Always trips
\n49 The wrong system loaded Always trips
\n50 DPL Maths fault – e.g. divide by zero, overflow etc Trips if #17.14=1
\n51 DPL array index out of range Trips if #17.14=1
\n52 User-generated trip from control word Always trips *
\n53 DPL Program incompatible Always trips
\n54 DPL Overload – Clock tick too short Trips if #17.14=1
\n55 RS485 trip – Mode 3 Trips if #17.14=1
\n56 Option board and system incompatible Always trips
\n57 Illegal OSCall Always trips
\n58-59 Internal Error Trips if #17.14=1
\n60-69 Option generated trip Trips if #17.14=1 *
\nPrc2 *Watchdog Trip.See the DPL command WDOG for information
\nNote: The watchdog trip can be disabled by setting #17.18 to 0.
\nCTTG128.doc V1.0 2 04\/12\/05<\/p>\n

Important Notes:
\n*When a trip occurs, all tasks of the DPL program will be halted (real-time tasks will
\nfirst complete) and any ERROR task is executed. The only exception to this is with trip 45, trip
\n52, trip 60 with certain option cards, the Watchdog trip (Prc2) and any other normal drive trips.
\nOther Notes
\nThe line number is only available when the program was compiled with debugging information.
\nAny other trip numbers that appear are either generated by the drive itself or the DPL program.<\/p>\n
