Actual speed monitoring

For linear axes, the limit for speed monitoring is compiled at a fixed value of 250 mm/s.

For rotary axes or spindles, parameterisation is required because of the component diameter. This is why the limit is set in the ACHSMDS list by means of the gear parameter "vb_monitor" (P-AXIS-00311). If the parameter is not in the list or is "0", the actual speed is monitored for "vb_not_referenced" (P-AXIS-00268).

• In the SAI, the error message 60241 (P-ERR-60241) "Programmed speed exceeds monitoring limit" if a high-speed motion is commanded.
• In the ISG-MCE, speed monitoring is active by default and can be deactivated with a special safety function, which must be called up cyclically.
• The actual speed is monitored cyclically in the system clock in the BF LR. If the permissible actual speed is exceeded, the error message 70225 (P-ERR-70225) "Max. actual speed exceeded during active speed monitoring" is issued and the axis is stopped by closing of the brake and removal of controller enabling.
