Actual speed monitoring

Actual speed monitoring is realised in the ISG-MCE.

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

For rotary axes or spindles, parameter definition must be possible on the basis of component diameter. This is why the limit is set in the ACHS_MDS list using 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” is output if a motion task is commanded at a higher speed.
• 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.
