ATV12 Environment: All Cause: Getting an SCF1 fault on the drive. If a fan is installed, verify correct operation of the fan. A command was sent that requires the drive to be in the operating state Operation Enabled (for example, a command to change the operating mode). Index pulse is too close to the switch. eSM module: System error detected: Error detected during dynamization of STO signal, eSM module: System error detected: Nonvolatile memory incorrect checksum (default values loaded), eSM module: Safety module replaced (default values loaded). Schneider Electric - CCC Expert VSD - A.Dufoss - 16/10/2014 . Verify all connections and cables used for data exchange. If monitoring functions of the drive detect an error, the drive generates an error message. The calculated offsets for the current sensors are out of range. Restart the . Original state of a parameter cannot be restored after an error was detected during recalculation of parameters with user-defined units. An attempt is made to change one of the parameters RESext_ton, RESext_P or RESext_R even though the external braking resistor is active. Verify resolver cable: wiring and shield connection. Welcome the the Schneider Electric French website. Command sent which is not permissible when the motor is not at a standstill. Change of motion blend during the ongoing motion blend (end position of motion blend not yet reached). Disable the power stage and repeat the command. Resolution: This is a Short-circuit fault or grounding fault at the drives output. eSM module: Input ESMSTART high instead of low (manual start). Connect an encoder to the input for encoder 1 before trying to set the absolute position directly via ENC1_abs_pos. System error detected: Motor encoder (Hiperface), System error detected: Motor encoder initialization. If you only have the cheap little LED seven segment display screen this is tougher to navigate. Privacy Policy. In the case of overtemperature, use a motor with a higher winding voltage or use a drive with a lower nominal supply voltage. Welcome to the Schneider Electric corporate Website, Access mySchneider, your personalized digital experience. The frequency of the pulse signal (A/B, Pulse/Direction, CW/CCW) exceeds the specified range. E A325, E A326, E A327, E A328 or E A329. Threshold value can be adjusted via the parameter MON_p_dif_warn. Title: Toshiba E3 ASD Landis and Staefa FLN Interface Manual.pdf Author: Tanya Keywords: TRIAL MODE / Expert features: Print encrypted PDF documents 2019 Schneider Electric. Oscilloscope: No additional data available, Oscilloscope: Parameterization incomplete, Oscilloscope: Trigger variable not defined, Autotuning: Moment of inertia outside permissible range. Verify supply voltage, cabling and function of switch. Adjustment value of the encoder of the third party motor has not yet been determined. This applies to the following series: Altivar ATV12, ATV312, ATV32, ATV61, ATV71. eSM module: System error detected: Indeterminable state of eSM state machine. eSM module: Parameter checksum error detected. Code 8503 / external diag. The recalculation has been started prior to the initialization. Operating mode Electronic Gear with processing method 'Position synchronization with compensation movement' has been activated which resulted in a position change greater than 0.25 revolutions. New command was sent before motor standstill was reached after a HALT request. Limit switch or reference switch signal not defined for signal input function. Clear break condition with command Fault Reset. Verify that the configuration file is valid and matches the type and version of the drive. Bridging progress and sustainability for all. VFD ERROR CODES Some VFD issues can be resolved before requesting service. Check the cables connecting the drive to the motor, and the motor insulation Connect motor chokes SCF3 Ground short circuit SCF4 IGBT short circuit Internal power component short circuit detected at power on Contact your local Schneider Electric representative SOF Overspeed Instability Overspeed associated with the eSM module: System error detected: Position evaluation error detected (values not identical). Reference movements require limit switches. Assign the signal input functions Positive Limit Switch, Negative Limit Switch and Reference Switch. Movement to new reference position is not possible after a limit switch has been triggered and a Fault Reset has been performed. Reach out to our customer care team to receive more information, technical support, assistance with complaints and more. Get monthly updates from Schneider Electric delivered right to your inbox. The drive only checks this for the first velocity jump. Not possible to load parameters into safety module eSM. Resolution of scaling too high (range exceeded), Change for jerk filter input position too great. eSM module: System error detected: States of eSM state machines not identical, eSM module: Output AUXOUT1 (cross fault to another output detected). Change eSM state to write this parameter. Motor movement during Safe Operating Stop (SOS). What is an SCF1 fault on the ATV12 drives? | Schneider Electric Global Contact your Schneider Electric service representative or replace the device. Velocity too high for the encoder. +*hec Schneider Electric Altivar 212 Trip and alarm codes Get answers you need by browsing topic-related Frequently Asked Questions (FAQ). The difference between the actual position and the reference position is too great. Please enter a valid email address, Problem with captcha verification, please check your connection. eSM module: System error detected: Stack overflow, eSM module: System error detected: Program sequence control (communication), eSM module: System error detected: Program sequence control (Idle task), eSM module: System error detected: Firmware checksum, eSM module: Parameter outside of permissible value range. Verify signal input for reference value signal. Change the system inertia used for velocity observer calculations via the parameter CTRL_SpdObsInert. Change the cycle time in the master controller to a cycle time supported by the drive or verify synchronization requirements. PacDrive Diagnostic Messages Verify that the motor is at a standstill at the beginning wake and shake procedure. Select "Macro-Confuguration", Scroll down and select "All" for all parameters, Scrolldown and select "Go To Factory Settings" Select "Yes" > Enter When it changes back to saying "No" it is done. For more details, please read our Internal nonvolatile memory not operative. The memory card has been write-protected. Schneider Electric - CCC Expert VSD - A.Dufoss - 16/10/2014 1. Search topic-related frequently asked questions to find answers you need. Privacy Policy. Contact your Schneider Electric service representative. Reference movement to index pulse cannot be reproduced. System error detected: Motor encoder inoperative, System error detected: Length specification for user data too great, System error detected: Communication with encoder not possible, Motor without electronic motor nameplate (for example, SER motor), No data segment of the electronic motor nameplate, System error detected: Motor configuration cannot be written, Not possible to write motor configuration, Incorrect encoder type selected with parameter MotEnctype, Error detected during the internal conversion of the motor configuration, Parameter of the motor configuration out of permissible range. 3) ATV320 Programming Manual Date : 09/30/2021 Type : User guide Languages : English Version : 04 Document Number : NVE41295 Download Add to my Documents Files File Name ATV320_Programming_Manual_EN_NVE41295_04 PDF (4.1 mb) Your browser is out of date and has known security issues. 8503 SERCOS service channel error detected - Schneider Electric Absolute position is different from incremental position, Amplitude of analog signals too high, limit of AD conversion exceeded. Adapt the frequency of the reference value signal to match the input specification of the drive. % The frequency of the external reference value signals (A/B signals, P/D signals or CW/CCW signals) is higher than the permissible value. Activation of a motion blend without movement. eSM Disable requires the safety module eSM to be in operating state Operation Enabled.
