maxon motor control 4-Q-EC Servoamplifier DES 70/10
Order number 228597
Operating Instructions April 2006 Edition
The DES (Digital EC Servoamplifier) is a very efficient digital
servoamplifier with sinusoidal current commutation for
perfectly controlling EC (Electronic Commutation) motors.
The EC motors must be equipped with Hall sensors and a
digital encoder with line driver.
Control, monitoring and complete control algorithms are
carried out in a very fast digital signal processor.
As with classic, conventional automatic controllers, easy
trimming and adjustment of the servoamplifier is possible,
with just a few potentiometers.
As an alternative, configuration is also possible using a
PC (RS232 or CAN). This is particularly beneficial with
series application, as all adjustments and parameters can
be set quickly, numerically and easily reproduced.
The set value specification can be made conventionally
with an analogue input (0 ... 5 V or ±10 V), RS232 or CAN
bus interface.
The sinusoidal commutation causes minimal torque ripple
and low motor noise.
