Nominal Speed Value Monitoring - HEIDENHAIN iTNC 530 Technical Manual

6.11.2 Nominal Speed Value Monitoring

6 – 164
MP1150 Position monitoring
MP1150.0 Delay time for deleting the nominal velocity value with the
deletable error message: Excessive servo lag in <axis>
Input: 0 to 65.535 [s] Recommended: 0
MP1150.1 Time period for which the monitoring function is to remain off
after the fast PLC input defined in MP4130.0 is set
Input: 0 to 65.535 [s]
0: Monitoring functions on
Recommended: 0.2 to 0.5
MP1150.2 Minimum time period for which the monitoring functions are to
remain effective after expiration of the time from MP1150.1
Input: 0 to 65.535 [s]
MP1410.x Position monitoring for operation with velocity
feedforward control (erasable)
Input: 0.0010 to 30.0000 [mm]
Recommended: 0.5 mm
MP1420.x Position monitoring for operation with velocity
feedforward control (EMERGENCY STOP)
Input: 0.0010 to 30.0000 [mm]
Recommended: 2 mm
MP1710.x Position monitoring for operation with following error
(erasable)
Input: 0.0000 to 300.0000 [mm]
Recommended: 1.2 · following error
MP1720.x Position monitoring for operation with following error
(EMERGENCY STOP)
Input: 0.0000 to 300.0000 [mm]
Recommended: 1.4 · following error
For the axes, the nominal speed value monitoring is effective only in operation
with velocity feedforward.
For the spindle, it is effective in operation with following error as long as the
position control loop is closed (orientation).
If the nominal speed value calculated by the position controller is greater than
the maximum possible nominal value, the blinking error message NOMINAL
SPEED VALUE TOO HIGH <AXIS> appears and the control-is-ready output is reset.
Analog axes: Maximum nominal value = 10 V
Analog spindle: Maximum nominal value = 20 V
Digital axes and spindle: Maximum nominal value = maximum motor speed
