AMPVER Command, December 2007
Caution
Failure to execute the AMPVER command on power-up for firmware
1.943 and earlier can result in equipment damage.
Geo Brick Drives, firmware version 1.943 and earlier, require a minimum delay of 500 milliseconds and
the issuing of AMPVER command on power up. This will ensure establishing communication between
the amplifier processor and the PMAC, thus conveying amplifier faults and status properly.
Example:
OPEN PLC 1 CLEAR
DIS PLCC 0..31
; Disable all compiled PLCs
DIS PLC 0 ; Disable foreground PLC
DIS PLC 2..31 ; Disable background PLCs
I5111=500*8388608/I10 ; 500 ms delay using C.S1 countdown timer
WHILE(I5111>0)
;
END WHILE ;
CMD"AMPVER" ;
I5111=20*8388608/I10 ; 20 ms delay using C.S1 countdown timer.
WHILE(I5111>0)
; This provides enough time for the drive
END WHILE ; to process the ampver command.
ENAPLC 2..31 ; Re-enable background PLCs
ENAPLC 0 ; Re-enable foreground PLC
ENA PLCC 0..31 ; Re-enable all compiled PLCs
DISABLE PLC 1 ; Disable PLC 1, run only once on power up or reset
CLOSE
Quick Verification:
The TYPE command, issued from a terminal window should return TURBO2, AMP, X4
This is the desired response. A response of TURBO2, X4 is not appropriate (the Drive should not be used
in this case) and it implies that the PLC has not executed properly (i.e., I5 setting) and/or the AMPVER
command has not been issued, or executed properly.
Note
Geo Brick Drives, with firmware version 1.944 and later do not
require sending AMPVER command on power-up
