Hexadecimal Representation of Trips
When more than one trip is to be represented at the same time then the trip codes are simply
added together to form the value displayed. Within each digit, values between 10 and 15 are
displayed as letters A to F
For example referring to the tables above, if the ACTIVE WORD 1 parameter is
02A8 , then
this represents:
a
“ 2 ” in digit 3
an “8” and a “2” in digit 2
(8+2 = 10, displayed as A )
an “ 8 ” in digit 1
This in turn represents the active trips BRAKE RESISTOR, MOTOR STALLED, INPUT 1 BREAK and HEATSINK TEMP, (an unlikely
situation).
( In decimal representation, 02A8h is 680d
680 = 512 + 128 + 32 + 8
This in turn represents the active trips BRAKE RESISTOR, MOTOR STALLED, INPUT 1 BREAK and HEATSINK TEMP)
In the same way, the ACTIVE WORD 2 parameter displaying
02A8 would represent CURRENT LIMIT, DESAT (OVER I), TRIP 22 and 24V
failure, (another unlikely situation).
The hexadecimal value is used over comms, however, pressing the M key whilst displaying the hexadecimal trip value will show the list of all trips
and their current values
