Wait until motor has come to a complete standstill. eSM Disable requires the safety module eSM to be in operating state Operation Enabled. No zero point defined by means of operating mode Homing. Configuration error detected: Invalid BISS encoder parameter setting. System error detected: Position initialization not possible. Absolute position is different from incremental position, Amplitude of analog signals too high, limit of AD conversion exceeded. A Quick Stop has been triggered via the fieldbus. From 6 long-term commitments to sustainability research and consulting, we are committed to being part of the solution by engaging our entire ecosystem in sustainable progress. Velocity value determined by velocity observer is incorrect. Wait for the running recalculation for scaling to finish. Enjoy! See the chapter Parameters for the parameter that requires a restart of the drive. The parameters have been reset to the default values. Value in parameter CTRL_v_max or resolution or the encoder simulation ESIM_scale are too high. I'd like to receive news and commercial info from Schneider Electric and its affiliates via electronic communication means such as email, and I agree to the collection of information on the opening and clicks on these emails (using invisible pixels in the images), to measure performance of our communications and improve them. % Velocity range exceeded (parameter CTRL_v_max, M_n_max). Use a differently sized motor that can withstand the load torque. In this case, operation with velocity observer is not possible and the velocity observer must be deactivated. eSM module: Output /INTERLOCK_OUT (cross fault to another output detected), eSM module: Output RELAY_OUT_A (cross fault to another output detected), eSM module: Output CCM24V_OUT_A (cross fault to another output detected), eSM module: Output AUXOUT1 (cross fault to 24 V detected). The selected type of usage of the analog inputs is not possible. Maximum velocity of the encoder is exceeded. Verify limit switch function and connection. Retry loading the parameters into the safety module eSM. Verify the position of the motion blend and the movement range. eSM module: No speed limit for negative direction set for direction-dependent SLS. Schneider Electric - CCC Expert VSD - A.Dufoss - 16/10/2014 . Power stage cannot be enabled in the operating state Not Ready To Switch On. What Is in This Chapter? -Check all the cables connecting the drive and motor. Change eSM state to write this parameter. The cycle time tolerance may not exceed one quarter of the set cycle time. An external tool has tried to lock the configuration of the drive for upload or download. o 8009 Program reset Bridging progress and sustainability for all. Module in fieldbus slot not correctly detected. Attention: these dimensions concern fixing holes. stream Parameter write not permissible (READ only).

Verify parameter configuration of ESMSTART. The same signal input function has been assigned to at least two inputs. The acknowledgement signal must be available for less than 6 seconds. The motor only works with a PWM frequency of 16 kHz (motor nameplate entry). Speed limit for multiple SLS in positive direction has a value of zero. The activation of a new operating mode is not possible, the error code is sent as the response to the activation command.

Amplitude of analog signals from encoder too high, signals are clipped, Signal position evaluation of analog encoder inoperative, Error detected with quasi absolute position. RS485/Modbus: Incorrect number of monitor objects. Use correct password. Enjoy! Continuation of interrupted movement in operating mode Profile Position is not possible because another operating mode had been active in the meantime. Incorrect communication between module and encoder. The Quick Stop option code has been set to -1 or -2 which causes the drive to transition to the operating state 9 Fault instead of the operating state 7 Quick Stop Active. The hardware revision does not support the function. Cyclic communication: The selected cycle time tolerance is too high. Error response can be adjusted via parameter ErrorResp_p_dif. Special login is required for Manufacturing Test Firmware, Position capturing has not yet been activated. Activate a jog movement with positive direction of movement (target limit switch must be connected to the positive limit switch). This blog considers the cause of a motor overload fault (OLF) on Altivar drives. eSM module: Parameter cannot be written in this operating state. Verify setting of parameter WakesAndShakeGain. Modify the parameter AT_n_ref or AT_n_tolerance to meet the required condition. If monitoring functions of the drive detect an error, the drive generates an error message. Oscilloscope: No additional data available, Oscilloscope: Parameterization incomplete, Oscilloscope: Trigger variable not defined, Autotuning: Moment of inertia outside permissible range. ATV12 Environment: All Cause: Getting an SCF1 fault on the drive. Connected type of EnDat encoder is not supported, Configuration error detected: Invalid SSI encoder parameter setting. Incorrect motor data, for example motor resistance, motor inertia (in case of rotary motors) or motor mass (in case of linear motors). Under Faults- Causes- Remedies sections. Remove the cause of the stop and restart Autotuning. The recalculation must be started after the initialization. eSM module: Parameter checksums not identical. This may have been caused by an external load. Verify cable specifications, shield connection and EMC.

Analog and digital encoder signals subject to massive interference. The master controller may be unable to provide the required synchronization signals at the set cycle time, for example, due to insufficient computing power. Status and warning messages Fault messages 179 diagnostics running display options Zero point no longer valid due to movement beyond permissible movement range. Drive is in operating state Fault or Fault Reaction Active.
