1 Preface and general information
The ETC Motion Control as the leading element of automation is together
with the Lenze drive controllers and motors an optimal system solution for
the control of movements.
In the ETC system both compact controls for installation on top hat rails and
PC insert cards are available. In both hardware designs either a NC or a MC
core can be supplied. The programming of the NC is carried out in accordance
with DIN 66025 (G code), that of MC in accordance with PLCOpen. Both
controls also include a PLC with is programmed in accordancd with 61131−3.
The control system is complemented by the corresponding I/O
subassemblies.
The communication with the drives via CAN or to the PC level via Ethernet
TCP/IP is also integrated into the ETC.
1.1 About this Manual
This manual is intended for all those who plan, install, program or
commission the ETC Motion Control System under the "NC" operating
system.
The ETC device manual contains information on the following topics:
ƒ Technical data
ƒ Structure and function of the system components including interface
description
ƒ Mounting, connecting and maintaining system components
This manual is complemented by the software manuals "MC operating
system" and "NC operating system", which provide important information
for the programmer and commissioner.

The core of the automation system is the ETC control in the top hat rail design
(ETCHx) or as PCI insert card (ETCPx).
The top hat rail design ETCHx is normally used in a so−called ETC island
(¶ 16); it communicates via Ethernet with the applications on the IPC (or
standard PC).
The ETCPC is inserted into the IPC (or standard PC) and communicates with
the applications via the PCI bus.
Both designs have two separate CAN busses:
ƒ At CAN1 bus (or also ME bus) the I/O modules and any operating
components are connected. Third party devices must comply with teh
DS401 profile of the CANopen specification.
ƒ The drives (e.g. the ECS compact servo) are connected to the connection
for the Motion CAN bus (CAN2) at the front plate. External drives must
comply with the profile DS402 of the CANopen specification and in
particular support the "Interpolated Position Mode".

To carry out its allocated control function the ETC control needs various
programs which are transferred from the IPC (or standard PC):
ƒ Operating system or firmware of the control (e.g. ETCHC.rsc)
ƒ PLC programs (e.g. SPSDummy.prg)
ƒ CNC programs; i.e. cycle and DIN programs (e.g. 9000.zyk or
Nikolaus.din)
The ETC control is operated and maintained via the IPC (or standard PC). The
following applications might run on it:
ƒ Windows 2000 or XPoperating system
ƒ Terminal program (e.g. HyperTerminal) for establishing the Ethernet
connection between IPC and ETCHx control and for the configuration of
the ETCHx control via the monitor interface (e.g. firmware update). This
is not required for the ETCPx.
ƒ ETC−MMI gateway as communications program between Windows
applications and the ETC control.
ƒ Lenze ETC−MMI for the configuration, operation and monitoring of the
ETC control and for creating CNC programs.
ƒ CoDeSys development environment for the creation and testing of PLC
programs.
)Note!
An external keyboard is required at the IPC for commissioning. It
is not required for normal operation.

module ETCHT000.

Several ETCHx islands can be connected to form a complete system. Please
note the maximum permissible cable length per CAN level dependent on the
Baud rate (¶ 56). The maximum number of modules in one ETCHx island is
limited by the following constraints.
CAN Bus max. 127 modules
Module address max. 16 modules of the same type
Power supply
unit
In practice the capacity of the power supply unit is the decisive factor for
the maximum number of modules in an island. The current consumption of
the individual modules both via the 24 V and the 5 V supply is relevant and
must be taken into account.
Typically 15 modules can be supplied with one power supply unit
ETCHN003.
The power consumption of the individual modules fromthe 5 V voltage
produced in the power supply unit is shown in the following table.
The figure for "typ." refers to the 24 V supply voltage and with a high signal
being present at half the digital inputs and outputs.
The figure for "max." refers to the 32 V supply voltage and an operating state
with maximum power consumption.

The ampacity of the cables and plug−in connectors of the internal system bus

3.1.3 Set node address
Every ETCHx I/O module in a line represents a separate node at CAN1 bus and
must be set up with a unique node address.
ETC025
The node address is set via a front Hex switch (4 low value address bits) and
via permanently wirded bridges within the housing (3 high value address
bits). This means that a maximum of 16 modules are possible within a
module type.
)Note!
Some modules have internal codings switches instead of the
permanently wired bridges for the optional modification of the
high value address bits.

3.2 Control in top hat rail design (ETCHx)
The ETCHx is a control for top hat rail assembly. Up−to−date communication
interfaces like Ethernet TCP/IP for networking and PC−MMI connection and
dual CANopen for the connection of field bus terminals or digital drive
amplifiers make the ETCHX ideal for use in machines with a distributed
control structure.
The connection to other modules is via the integrated ME bus.

4 MByte static SRAM (32 Bit RAM) and 2 MB Flash PROM are available.
ETCHC: The firmware has a memory requirement of 1 ... 1.5 MB SRAM and
1 MB Flash PROM. This means that the user has 2.5 ... 3 MB SRAM and 1 MB
Flash PROM available. This is sufficient for e.g. typically 12 NC sentences
(preprocessing buffer), 512 kB PLC program, 12 kB PLC data and 1 MB SPV
memory (DIN program memory).
ETCHM: The firmware has a memory requirement of 1 MB SRAM and 1 MB
Flash PROM. This means that the user has 3 MB SRAM and 1 MB Flash PROM
available. Verfügung. This is sufficient for e.g. typically 2000 kB PLC program
and 1000 kB PLC data.
The memory allocation can be configured by the user.
