Complete Guide to Lenze ECS Servo System

Improve input current waveform and reduce harmonic distortion rate

Reduce the impact on the power grid and improve the power factor

Reduce the AC load on the electrolytic capacitor of the DC bus and extend the lifespan of the driver

Selection example: ECSEE012 power module corresponds to ELN3-0150H024 (24A), ECSEE040 corresponds to ELN3-0055H055 (55A).

5.3 SinCos Encoder Interference Filter

When the motor cable is long (>25m) or the on-site grounding is not ideal, the encoder signal may be interfered with, causing position jitter or runaway. Lenze provides the EZZ0014 interference filter (9-pin Sub-D adapter), which can be directly installed on the encoder input interface to effectively suppress common mode interference.

Control connection and fieldbus

The control terminals of the ECS servo system adopt a plug-in design (maximum 1.5mm ²). The main interfaces include:

1 analog input: ± 10V or 0-20mA, 11 bits+symbol resolution

4 digital inputs: compliant with IEC 61131-2, 24V level

2 digital outputs: 1 50mA, 1 1.5A (can directly drive small brakes)

2 CAN bus interfaces: Supports CANopen protocol, with a minimum cycle time of 1ms, used for multi axis synchronization

1 AIF expansion slot: capable of inserting communication modules such as Profibus, DeviceNet, Interbus, LECOM, etc

Encoder interface: 9-pin Sub-D, supports SinCos/TTL incremental encoder, Hiperface absolute encoder (single/multi turn)

Engineering Tip: Digital frequency input/output (two tracks) can achieve electronic gear synchronization between multiple axes without the need for upper level controller intervention. In the installation of push through or cold plate, it is necessary to use the original Lenze shielding connection kit ECSZS000XOB001 to ensure reliable high-frequency grounding.

Software Features and Application Solutions

The ECS servo system is divided into three versions according to control requirements:

Speed&Torque: Pure speed/torque control, supporting 15 preset speeds, S-shaped acceleration and deceleration, and motor brake logic.

Motion: Angle synchronization based on CAN motion bus, suitable for electronic camshafts (master-slave following).

Application: Fully programmable, supports five languages of IEC 61131-3 (IL, LD, FBD, ST, SFC), can load the following software packages:

7.1 Positioner software package

Up to 128 positioning configurations, can be executed in any order

Support absolute, relative, and modular positioning

Jerk limitation, speed/acceleration multiplier, target position reaching tolerance

16 reset modes with Teach in function

Application: Material transfer, stacking, rotating worktable, robot

7.2 Cam software package (Cam)

Up to 48 cams, with a maximum of 4096 interpolation points per cam

Virtual spindle supports jog, handwheel, periodic operation, and automatic mode

Online stretching, compression, phase shift cam curve

Built in Cam Designer Basic Edition for graphically creating motion curves

Application: contour machining, filling, packaging, cross cutting

7.3 Winder software package for winding machine

Three modes: open-loop tension control, closed-loop tension control, and dance roller control

Automatically calculate roll diameter, inertia, and friction compensation

Acceleration torque feedforward, material density self identification

Application: Central winding/unwinding (cable, textile, paper, film)

7.4 Prepared Solutions

Flying cutter: The processing tool synchronizes with the material movement and returns after cutting is completed. Suitable for fixed length cutting, printing, and marking.

Cross cutting: The rotating knife drum synchronizes with the material during cutting phase, supporting color correction, gap control, and continuous/asynchronous cutting.

These solutions can serve as extension functions for ECSA (Application) controllers, greatly reducing programming and debugging time.

Engineering software and debugging tools

8.1 Global Drive Control (GDC)

GDC is Lenze's traditional parameter setting and diagnostic software, characterized by:

Short Setup Wizard to quickly complete basic parameters

Function Block Editor (interconnecting function blocks without programming knowledge)

Built in oscilloscope (multi-channel recording, trigger conditions can be set)

Supports LECOM, CAN system bus, USB adapter (EMF2177IB) communication

The free version of GDC easy can be downloaded from the Lenze website, and the paid single user license ESP-GDC2 provides all features.

8.2 Drive PLC Developer Studio (DDS)

Integrated development environment for programming ECS Application and 9300 Servo PLC:

Support IL, LD, FBD, ST, SFC, and CFC editors

Online debugging, breakpoints, variable monitoring, simulation

Seamless integration with GDC and GD Oscilloscope

It is recommended to purchase the professional version (ESP-DDS2-P) to obtain the CFC editor and graphical visualization.

8.3 Global Drive Oscilloscope

Without the need for external measuring instruments, 8 channels of variables (speed, torque, current, position error, etc.) can be directly collected from the drive memory. The sampling time can be configured and recording before/after triggering is supported. It is very practical for optimizing control loops and analyzing mechanical resonance.
