75274 [Channel %1: ] RCTR: Excessive velocity near pole, error code %2
Parameters: %1 = Channel number
%2 = Error code
Definitions: Excessive velocity of the machine axes involved can oocur when traversing near the pole with active
transformation, especially in JOG mode. The alarm is triggered if excessive velocity or acceleration
occurs for an output axis of the transformation (MCS).
Error code:
0: Position jump
1: Excessive velocity
2: Excessive acceleration
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Reduce velocity. Avoid JOG traverse near pole.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
75275 [Channel %1: ] RCTR: block: %2, unreachable position on interpolation
Parameters: %1 = Channel number
%2 = Block number
Definitions: On block interpolation a non-approachable position is detected:
Reaction: NC Start disable in this channel.
Alarm display.
NC Stop on alarm.
Remedy: Modify part program.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
75500 [Channel %1: ] HSLC: Configuration error ID=%2
Parameters: %1 = Channel number
Definitions: The function CC_FASTON or CC_FASTON_CONT cannot be executed because the following MD
configuration is incorrect:
ID=2: The NCK system function "Timer-controlled cam signal output" (see Description of Functions
"Software cams, Position switching signals (N3)" ) is configured with machine data MD 10480
$MN_SW_CAM_TIMER_FASTOUT_MASK > 0 at the same time as the function HSLC. As there is
only one hardware timer on the NCU, only one of the two functions can be used.
ID=4: Programming CC_FASTON and CC_FASTON_CONT requires internal block memory:
In order to activate the compile cycle CCHSLC, the entries have to be increased in the following
machine data:
MD 28090 $MC_MM_NUM_CC_BLOCK_ELEMENTS by 1 element
MD 28100 $MC_MM_NUM_CC_BLOCK_USER_MEM by 2 [KB]
Reaction: Alarm display.
Remedy: Modify the stated MD settings
Program Con- Clear alarm with the RESET key. Restart part program
