20170 [Channel %1: ] Machine data $AC_FIFO invalid
Parameters: %1 = Channel number
Definitions: the structure of the FIFO variable $AC_FIFO1 - $AC_FIFO10 determined by machine data MD28260
$MC_NUM_AC_FIFO, MD28262 $MC_START_AC_FIFO, MD28264 $MC_LEN_AC_FIFO, MD28266
$MC_MODE_AC_FIFO cannot be stored in the R parameter field defined in MD28050 $MC_MM_NUM_R_PARAM.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Increase the number of the R parameters or reduce the
FIFO elements.
MD28050 $MC_MM_NUM_R_PARAM = MD28262 $MC_START_AC_FIFO + MD28260 $MC_NUM_AC_FIFO *
(MD28264 $MC_LEN_AC_FIFO + 6)
Program Switch control OFF - ON.
Continuation:
20200 [Channel %1: ] Invalid spindle number %2 with tool fine compensation
Parameters: %1 = Channel number target channel
%2 = Spindle number
Definitions: There is no spindle/axis assignment in the target channel for the spindle specified in the PUTFTOC command.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Modify program in channel that writes the tool fine compensation.
Program Clear alarm with the RESET key. Restart part program
Continuation:
20201 [Channel %1: ] Spindle %2 no tool assigned
Parameters: %1 = Channel number
%2 = Spindle number
Definitions: In order to make allowance for the fine tool compensation for the tool currently in the spindle, a spindle/tool assignment
must be active. This is not presently the case for the programmed spindle in the target channel of fine tool compensa-
tion.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: 1. Modify the part program (write the tool fine compensation).
2. Establish spindle/tool assignment by programming:
- TMON (tool monitoring)
- GWPSON (tool selection)
Program Clear alarm with the RESET key. Restart part program
