• MD36510 ENC_DIFF_TOL (measuring system synchronism tolerance)
Error response
• Alarm: "25105 Measuring systems are not synchronous"
and stopping the machine axes using a speed setpoint ramp whose characteristic is set in
• MD36610 AX_EMERGENCY_STOP_TIME (Time for braking ramp when an error occurs)
Figure 10-18 Monitoring for SINUMERIK 840D sl:
Notice
MD36620 SERVO_DISABLE_DELAY_TIME (Switchoff delay servo enable)
must always be selected greater than
