Note
Some functionalities may not exist in older firmwares.
Please refer to the respective section when using an older firmware:
Overview Functional description
CANopen over EtherCAT Description of the working principle.
Actuator configuration Contains information about motor and gear settings as well as a description of the brake release feature.
Motor and gear settings Description of the motor and gear parameters
Manually controlling phase D voltage Phase D can be used for a single phase device or custom brake options
Brake release Description of the brake release feature
User defined velocity units Users can change the default velocity unit for higher precision
Commutation Offset Detection Aligns the motor’s electrical angle with the position sensor feedback for motion control
Power limit Limits the mechanical output power of the motor
Encoders and I/O Description of analog and digial inputs and outputs and encoder configuration
Analog In How to set up analog encoders directly or using external scaled measurement
Analog Input Scaling Allows to do a nonlinear conversion of an analog voltage using a 5th order polynomial function.
Digital I/O Configuration of digital I/Os as input or output
Digital GPIO Assigns actions to changes in the Digital Inputs and triggers Digital Outputs
Encoder configuration Description of the most important encoder parameters
Commutation with Hall and ABI combined Hall sensors and ABI encoders can be combined for commutation.
Input counter Allows counting pulses in a particular pin of an encoder connector.
Protection Users can define limits for undervoltage, overvoltage and overcurrent.
Errors and warnings A list of all standard and SOMANET specific errors.
Errors thrown by the firmware SOMANET throws firmware errors as specified in CiA 402.
Error report object Each occurring error is described in the Error Report Object.
Remedies for protection errors How to resolve issues with over-current, over-voltage, under-voltage and over-temperature.
Logging Logs are provided at every state change as well as at each occurring error or warning.
Motion control Details about motion functions available via EtherCAT.
Cyclic synchronous torque control (CST) In torque control mode the master sends desired torques to the drive.
Cyclic synchronous velocity control (CSV) In velocity control modes the master sends desired velocities to the drive.
Cyclic synchronous position control (CSP) In position control modes the master sends desired positions to the drive.
Profile position mode In profile position mode the trajectory to a target point is generated on the drive.
Profile velocity mode In profile velocity mode the motor will rotate at a target velocity.
Profile torque mode In profile torque mode the drive sends a target torque to the motor.
Diagnostics opmode Used for triggering diagnostic OS commands.
Switching the modes Describes how the modes can be selected.
Control Loop Tuning Each motor needs to be tuned before it is operational. Synapticon provides an easy-to-use Auto-Tuning feature but all drives can also be tuned manually.
Extended control functionalities These features can be used to enhance performance:
Cogging Torque Compensation Removes ripples caused by magnetic interaction between motor rotor and stator.
Field Weakening The velocity range of electric motors can be extended by weakening the magnetic field of the rotor linearly over the speed range.
Anti-Windup Control An Anti-Windup alogorithm is used to prevent the Integrator part to accumulate beyond acceptable boundaries.
Gain Scheduling Applies controller gains which will change dynamically regarding the current speed.
Motor Overload Protection (i2t) This feature limits the overcurrent injected to the motor to prevent damage from overheating.
Velocity feed forward To increase the velocity of the robot’s reaction, the target position signal can bypass the position controller.
Torque Offset A desired offset torque can be added to the reference torque.
Velocity Offset An additional velocity offset can be used to improve the positioning performance.
Filtering Digital filters can be used to remove unwanted frequencies such as noise or nonlinear effects.
Command smoothing and Interpolation Successive setpoints can be smoothed, so that low command resolution and jitter have a reduced effect on the control.
Control supervision Allows to supervise the work of the control loops
Distributed clocks Allows to synchronize the system time for enhanced performance.
OS Command Offers commands that can’t be executed by single SDO operations.
Quick stop Stops the motor quickly in a controlled way.
