Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14815 [Channel %1: ] Block %2 negative thread pitch change programmed
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A negative thread pitch change has been programmed.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Correct the value assignment. The programmed F value should be greater than zero. Zero is allowed
but has no effect.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14820 [Channel %1: ] Block %2 negative value for maximum spindle speed
programmed with constant cutting speed
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: For the function "Constant cutting speed G96" a maximum spindle speed can be programmed with
the keyword LIMS=.... The values are in the range 0.1 - 999 999.9 [rev/min].
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Program the maximum spindle speed for the constant cutting speed within the limits given above. The
keyword LIMS is modal and can either be placed in front of or within the block that selects the constant
cutting speed.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14821 [Channel %1: ] Block %2 error in selection or deselection of GWPS
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: On selecting GWPS programming (constant grinding wheel surface speed) with GWPSON, one of the
following errors occurred:
- An attempt has been made to select the GWPS programming for a spindle that has already been
assigned to another tool by TMON, GWPSON, CLGON or activation of the tool length compensation.
- An attempt has been made to select a tool which has not been defined.
- An attempt has been made to select an edge (implicitely) which has not been defined (implicit selec-
tion: D1 of a tool, if no tool has been specified.)
- Selection does not refer to a grinding-specific tool (400-499).
- An attempt has been made to select GWPS for the active tool, although the TLC is not switched on.
- Selection refers to an invalid spindle number.
- A grinding wheel radius equal to zero has been specified.
On deselecting GWPS programming with GWPSOFF, one of the following errors occurred:
- Deselection does not refer to a grinding-specific tool (400-499).
- An attempt has been made to deselect GWPS for the active tool, although the tool length compen-
sation has not been activated.
- Deselection refers to an invalid spindle number.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: - Check GWPSON and GWPSOF command.
- Check tool compensation data:
$TC_DP1 : 400 - 499;
$TC_TGP1: Spindle number.
Program Con- Clear alarm with NC START or RESET key and continue the program.
