Introduction ETEL Doc. - Operation & Software Manual # DSC2P 903 / Ver. F / 3/6/05
Caution: Indicates electrostatic discharges (ESD), dangerous for the controller.
The components must be handled in an ESD protected environment only.
• Before installing or operating the controller, all the corresponding documentations listed page 15 as well as
the one related to the motor(s) used with it.
• Never use the controller for purposes other than those described in this manual.
• A competent and trained technician must install and operate the controller, in accordance with all specific
regulations of the respective country concerning both safety and EMC aspects.
• Troubleshooting and servicing are permitted only for ETEL's technicians and agreed distributors.
• Operating the controller will make the motor move.
Keep away from all moving parts to avoid
injuries!
• High voltage may be present on the power and motor connectors.
• Before connecting or disconnecting a cable on one of these connectors or touching the controller, turn off
all the power supplies and wait 10 minutes (2min for the DSCDM) to allow the internal DC bus
capacitors to discharge.
• All the connector must be handled in an ESD protected environment, only.
• The safety symbols placed on the controller or written in the manuals must be respected.
• In the controller, the leakage current through the protective conductor to the GND is greater than a.c. 3.5
mA.
If the controller is integrated into a machine, the manufacturer of this machine must establish that it fulfils the
89/336/EEC directive on EMC before operating the controller.
How to use this manual
If you are not an experienced user, read first the Chapter A to catch the basis about the controller's internal
functioning and commands' syntax.
Then, follow step-by-step the Chapter B to successfully realize the first installation and setup of the
controller.
In Chapter C, §11.
and §12., all the basic functions necessary to operate the controller are described in
details. Chapter C, §13.
is reserved for experienced users and describes advanced functions only used in
specific applications.
Chapter D describes how to program the controller (movements sequences).
The appendixes in Chapter E include the registers and commands references lists (with commands
examples), as well as error and warning messages lists and units conversion formulas.
Remark: ETEL can provide its customers with training courses including theoretical presentation
and practice in real conditions, at our facilities in Môtiers (Switzerland).
Working principle
These digital position controllers have been designed for direct drive applications. They can work in
interpolated mode if they are mastered by a DSMAX motion controller (refer to the 'DSMAX User's Manual').
They can drive single-phase, two-phase and three-phase motors (two motors for the DSCDP, DSCDL and
DSCDM). You can obtain brushless torque and linear motors from ETEL as well as moving coils and moving
magnets. They can also drive brushless motors, DC motors, steppers (only if three-phase motors are star-
connected). They must be implemented with analog (incremental or absolute (EnDat2.1)) or TTL encoders
available on the market.
