03/2009 Overview of Alarms NCK alarms Program Continuation: 20095 Clear alarm with the RESET key in all channels of this mode group. Restart part program. Axis %1 illegal torque, current torque %2 Parameters: %1 = Axis name, spindle number %2 = Current holding torque when brake test selected Definitions: The current holding torque, when brake test selected, cannot be attained with the present parameterization of the brake test. Reaction: Alarm display. Remedy: Check the parameterization for the brake test function check: - The torque for the counterweight in the drive machine data p1532 should be nearly the same as the current holding torque. The current holding torque is displayed in the alarm text. - The torque set for the brake test MD36966 $MA_SAFE_BRAKETEST_TORQUE must be greater than the current holding torque. Program Continuation: Clear alarm with the Delete key or NC START. 20096 Axis %1 brake test aborted, additional information %2 Parameters: %1 = Axis name, spindle number %2 = Error information based on $VA_FXS_INFO Definitions: The brake test has detected a problem. The additional info provides more detailed information on the cause of the alarm. The explanation can be found in the $VA_FXS_INFO system variable documentation. Additional information: 0: No additional information available. 1: Axis type is not a PLC or command axis. 2: End position reached, motion completed. 3: Cancel by NC RESET (key reset). 4: Moved out of monitoring window. 5: Torque reduction rejected by drive. 6: PLC has cancelled enables. Reaction: Interface signals are set. Alarm display. Remedy: Note the supplementary conditions of the brake test, see additional info. Program Continuation: Clear alarm with the Delete key or NC START. 20097 Axis %1 incorrect travel direction brake test Parameters: %1 = Axis name, spindle number Definitions: Due to the selected travel direction, the brake test for the current load torque is performed with an incorrect torque. Reaction: Alarm display. Remedy: - Perform the brake test for the other travel direction - Adjust drive parameter p1532 better to the current weight ratio. The alarm will occur only if the current torque deviates from drive parameter p1532 by more than 7.5% of MD36966 $MA_SAFE_BRAKETEST_TORQUE when the brake is released. - Activate the automatic determination of the load torque at the beginning of the brake test via MD36968 $MA_SAFE_BRAKETEST_CONTROL, bit 0 = 1. Program Continuation: Clear alarm with the Delete key or NC START. 20100 [Channel %1: ] :Invalid configuration for digitizing Parameters: %1 = Channel number Definitions: - The digitizing function expects the definition of 3 geometry axes in the channel. - At the available baud rate for a transmission of the actual positions and setpoint velocities between the NC and the digitizing device, the interpolation cycle must be set to a minimum of 5ms. Reaction: Interface signals are set. Alarm display. Remedy: Please inform authorized personnel / the service department. - Define 3 geometry axes for the digitizing channel by means of machine data. - Use an interpolation cycle greater than 5ms. © Siemens AG, 2009.
