PS0003

TOO MANY DIGIT

Fanuc · Series 30i/31i/32i-MODEL B Parameter

What does PS0003 mean?

This alarm is issued when a value specified for an M, S, T, or B code exceeds the allowable number of digits. The maximum allowed digits are configured by parameters 3030, 3031, 3032, and 3033. For the B code, the ability to specify a decimal point, which affects the digit count, is controlled by bit 0 (AUP) of parameter No. 3450.

Common Causes

  • Input value for parameter 'TOO MANY DIGIT' exceeds allowed limit.
  • Data entry error for a numeric parameter.
  • Incorrectly formatted input for a digital parameter.
  • Validation failure for a string-based parameter.

  6. 6

    Review the NC program for the M, S, T, or B code causing the alarm — ensure the specified value does not exceed the allowed number of digits defined by parameters 3030-3033.
