B–62755EN/011. DISPLAY AND OPERATION OF CRT/MDI1.10WAVE FORMDIAGNOSTICFUNCTIONTuning becomes easier by graphically displaying servo error amount andtorque command, etc. (Graphic option is required).The following two types of waveform diagnosis functions are supported:(1)One–shot typeThe one–shot type waveform diagnosis function can graphicallydisplay, as a waveform, any variation in those data items listed below.The start of data sampling can be triggered by the rising or falling edgeof a machine signal. This function facilitates the adjustment of theservo and spindle motors.a. Error, pulse distribution amount, torque, speed, current, andthermal simulation data for the servo motor of each axisb. Composite speed for the first, second, and third axesc. Spindle motor speed and load meter valued. On/off state of a machine signal specified with a signal address(2)Storage typeThe storage type waveform diagnosis function enables the storingof any variation in the data items listed below and, if a servo alarmoccurs, the graphical display (as a waveform) of the stored data. Theend of data sampling can be triggered by the rising or falling edgeof a machine signal. This function facilitates the estimation oferroneous locations. Stored data can be output via the reader/punchinterface.a. Error, pulse distribution amount, torque, speed, current, andthermal simulation data for the servo motor for each axisNOTE1 To output stored waveform data, the optional reader/punchinterface must have been installed.2 The waveform diagnosis function is enabled when bit 0(SGD) of parameter No. 3112 is set to 1. Note, however, thata graphics board is necessary to display waveforms.1.10.1Setting Parameters3112#7(1)Set a parameter to utilize the servo waveform diagnostic function.#6 #5 #4 #3 #2 #1 #0SGD#0(SGD)0 : Do not display servo waveform (usual graphic display).1 : Displays servo waveform (usual graphic display function cannot beused.(2)Turn off the power once and turn it on again.3120 Time between servo alarm and sampling stop (storage type)[Data type] Word[Unit of data] ms[Valid data range] 1 to 3276069
