Code S51-002: Parameter Errors

Spindle parameter setting data is illegal. The alarm No. is the No. of the spindle parameter where the warning occurred. Remedy Check the descriptions for the appropri ate spindle parameters and correct them. Even when the parameter is set to a value within the setting range, an error is occurring due to the hardware compatibility or specifications or in relation to several other parameters. Refer to "Parameter Numbers during Initial Parameter Erro r" of each drive unit instruction manual for details. 00 Axis name Servo : Axis name Spindle : "S1", "S2", "S3" ... Alarm No. Message Alarm class Alarm class Message Name or "Servo warning" ter the following page is the double-digit number displayed ont-side of the drive unit. this number will be displayed in the last two digits of the of the servo warnings, refer to your drive unit's instruc- an alarm which occurred first is displayed on the alarm the drive monitor screen as necessary. Name Details Reset Stop method method An exce ssive difference in feedback amount was detected between the *- main side encoder and the MPI scale in MPI scale absolute position detec- tion system. An error was detected in the offset data that is read at the NC power-ON in PR - MPI scale absolute posi tion detection system. The difference between the magnetic pole position after the phase Z has PR - been passed (magnetic pole shift amount:SV028) and the initially detected position is excessive in the built-in motor's incremental control system.The magnetic pole is controlled by the initial detection value. An error was detected in the revolution counter data of the absolute posi- *- tion encoder. The accuracy of absolute position is not guaranteed. The battery voltage to be supplied to the absolute position encoder is drop- NR - ping. This warning is detec ted until the axis reaches the reference position during PR - the initial setup of the distance-coded reference check function. This warn- ing turns OFF after the axis has reache d the position, thus set the value dis- played on the drive monitor to the parameter. An input was detected in the signal related to the dual signal. *- Refer to "Dual signal warning (A4)" for details. A cooling fan in the drive unit stopped. * - Over-regeneration detection level exceeded 80%. * - A level of 80% of the Overload 1 alarm state was detected. * - An incorrect set value was detected among the parameters send from the *- NC in the normal operation. A contro l axis is being detached. (State display) * - In NC emergency stop. (State display) * Dec stop en- abled The power supply unit detected a warning. *- The error details are different accord ing to the connected power supply unit. *EA: Refer to "Power supply warning". Dec stop en- abled axis is removed, this warning can be reset with the NC RESET button. (Excluding warning 93.) Name Sub info Details Dual signal warning Axis name The system has been set in the STO state. The STO state is also entered at the time of emergency stop, but in this case, this warning will not appear be- cause the emergency stop has priority. Name Details Reset method The power was momentarily interrupted. NR Ext ernal emergency stop signal was input. * Ove r-regeneration detection level exceeded 80%. * A cooling fan built in the power supply unit stopped. * A warning was detected in the power backup unit (power supply option unit). * (Note 3) ton. This warning can also be reset with the PR an d AR resetting conditions. be reset with the NC RESET button. (Excluding warning 93.) Safety function warning 0001 (Axis name)
