Summary

Safety instructions

Basic safety instructions

Covers personnel qualifications and responsibilities for safe product operation, and process engineering considerations.

Application as directed

Defines the conditions and directives for operating the product correctly and safely, including compliance with EU directives.

Residual hazards

Identifies potential hazards associated with the product, including electrostatic sensitive devices, electrical voltage, leakage current, hot surfaces, and motor protection.

Commissioning

Important notes

Provides critical safety notes and prerequisites for commissioning, including wiring, motor connection, and emergency off functions.

Configuring the "Electronic Gearbox" TA

Configure position control

Operating mode "CiA 402 Cyclic sync position mode (csp)"

Details the default mapping for the cyclic sync position mode, including parameters received from the controller and sent to the controller.

Monitoring the position error

Explains position error monitoring for servo control, comparing system deviation to tolerance and defining error response.

Configure speed control

Operating mode "CiA 402 Velocity mode (vl)"

Details the default mapping for the velocity mode, including parameters received from and sent to the controller.

Operating mode "CiA 402 Cyclic sync velocity mode (csv)"

Describes the default mapping for the cyclic sync velocity mode, covering control words, status words, and operating modes.

Monitoring the speed deviation

Explains speed deviation monitoring for servo control, comparing system deviation to tolerance and defining error response.

Configuring the torque control

Operating mode "CiA 402 Cyclic sync torque mode (cst)"

Describes the default mapping for the cyclic sync torque mode, including control words, status words, and parameters for speed and torque limits.

Configuring the feedback system

Configure feedback system for motor control

Explains how to access parameter settings for motor feedback systems via EASY Starter, offering choices for resolver or encoder.

Synchronous motor: Pole position identification (PPI)

Explains pole position identification for synchronous motors, including requirements, methods, and monitoring.

Configuring the motor control

Servo control for synchronous motor (SC-PSM)

Describes the servo control for synchronous motors, detailing preconditions and required commissioning steps.

Servo control for asynchronous motor (SC-ASM)

Details the servo control for asynchronous motors, covering preconditions and required commissioning steps.

Motor protection

Motor overload monitoring (i²*t)

Monitors thermal utilization of the motor using currents and a mathematical model, including speed-dependent evaluation and UL 508 compliance.

Overcurrent monitoring

Monitors instantaneous motor current for protection, highlighting the importance of adapting the threshold and setting the maximum output current.

Testing the motor control

I/O extensions and control connections

Configure engineering port

Basic setting

Covers preconditions, automatic and manual configuration of the engineering port, including IP address, subnet mask, and gateway.

Configuring the network

Device functions

Device overload monitoring (i*t)

Explains the inverter's i*t utilization calculation for thermal overload protection, including warnings and error thresholds.

Additional functions

Safety functions

Safe Torque Off (STO)

Explains the STO safety function which prevents the motor from generating torque and movements, ensuring safe disconnection.

Safe Emergency Stop (SSE)

Details the SSE safety function, which has the highest priority and triggers based on external stop requests.

Ramp monitoring

Explains ramp monitoring for stop functions SS1 and SS2, ensuring deceleration ramps are not exceeded and triggering error stops.

Safe Stop 1 (SS1)

Describes the SS1 safety function that monitors stopping time and switches the inverter to STO if the time elapses or speed is too low.

Safe Stop 2 (SS2)

Explains the SS2 safety function that monitors drive speed within tolerance windows and switches to SOS or STO.

Safe Operating Stop (SOS)

Details the SOS function where the drive is not switched to torque-free operation, maintaining reached position and active control functions.

Safe Maximum Speed (SMS)

Monitors compliance with the safe maximum motor speed, triggering an error message if exceeded.

Safely-Limited Speed (SLS)

Monitors the parameterized speed limit (Nlim) and triggers an error stop if limits are exceeded or braking time elapses.

Safely Limited Increment (SLI)

Allows setting a maximum permissible position change and initiates an error stop if limits are exceeded.

Safe Direction (SDI)

Monitors motor rotation direction and parameterizable tolerance ensures drive does not change permissible direction.

Position-dependent Safe Speed (PDSS)

Monitors drive speed as a function of absolute position, allowing use of physically limited motion range without mechanical buffers.

Operation mode selector (OMS)

Switches between normal and special operation, activating safety functions like STO, SS1, SS2, SLS, and SLI.

Enable Switch (ES)

Allows overriding normal stop functions (STO, SS1, SS2) during special operation and repair mode.

Repair mode select (RMS)

Moves the drive from a blocking situation ('Deadlock'), restricting safety functions to STO, SS1 and monitoring effectiveness of enable switch.

Cascading (CAS)

Allows synchronized shutdown of an entire drive network, typically triggered by STO stop function.
