Siemens 14822 - Block incorrect programming of GWPS

When selecting GWPS (constant grinding wheel peripheral speed) with GWPSON or programming the GWPS with "S[spindle number] = value" one of the following errors has occurred: Invalid spindle number. Invalid parameter number for radius calculation in $TC_TPG9. The following values are valid: 3 for $TC_DP3 (length 1) 4 for $TC_DP4 (length 2) 5 for $TC_DP5 (length 3) 6 for $TC_DP6 (radius) Invalid angle in $TC_TPG8. The following values are valid: -90 <= $TC_TPG8 < +90. A grinding wheel radius equal to zero was specified Control reaction: Correction block is reorganized. Interface signals are set. Alarm display.

Safety

  • Spindle hazard: ensure the spindle is at standstill before working near it; follow lockout/tagout procedures.

Common Causes

  • When selecting GWPS (constant grinding wheel peripheral speed) with GWPSON or programming the GWPS with "S[spindle number] = value" one of the following errors has occurred: Invalid spindle number.
  • Invalid parameter number for radius calculation in $TC_TPG9.
  • The following values are valid: 3 for $TC_DP3 (length 1) 4 for $TC_DP4 (length 2) 5 for $TC_DP5 (length 3) 6 for $TC_DP6 (radius) Invalid angle in $TC_TPG8.

Troubleshooting Steps

  1. 1Check tool compensation data.
  2. 2$TC_DP1 : 400 - 499.
  3. 3$TC_TPG1: Spindle number.
  4. 4$TC_TPG8: Inclination angle for slope grinding wheel.
  5. 5$TC_TPG9: Compensation parameters for radius computation, e.g. 3 for $TC_GP3.
  6. 6Clear alarm with NC START or RESET key and continue the program
