1.2 PRODUCT RANGE
DS2000 is a full digital drive series for permanent magnet synchronous servomotors
(hereinafter: brushless) and for vector control asynchronous servomotors (hereinafter:
asynchronous).
The range is made up of 11 models, corresponding to 3, 4, 6, 8, 14, 20, 25, 30, 50, 60 and
100 A
rms
nominal currents.
The standard transducers provided with the motor are the incremental encoder or the
resolver (with its simulated encoder).
The recovery resistors are placed outside the drive; only the 3, 4, and 6 A models can be
equipped with built-in recovery resistor (optional).
DS2000 drive is provided together with this manual and the Application Notes in the
Appendix of DS2000 user’s manual, for a deep understanding and the best use of the
product.
1.3 GENERAL FEATURES
The DS2000 features provide the automation industry with the best response to the hardest
requirements related to motion control:
FULL DIGITAL:
• Speed and current control loops and many other functions, as the DC BUS status
monitoring, the soft-start and recovery circuit management, and the protections
thresholds detection are carried out through numeric algorithms.
• The digital mode allows a maximum stability related to the aging, the temperature and
the various application cases.
• Settings are carried out through numbers calculated by means of analytic models and
do not depend upon analog calibrations.
FLEXIBLE:
• Any brushless motor can be very well driven by entering a maximum of 8 parameters
which adjust the current loop and identify the motor electromechanical characteristics
(peak current, electromotive force, inductance, resistor, poles number, voltage rating,
speed).
• Any asynchronous motor can be very well driven by vector control, working as a
brushless servomotor; by entering the magnetization current (ID) and the slip gain
(frequency) additional parameters it is possible to use any kind of asynchronous
motor. The other parameters, the ones in connection with the hardware features in
common with brushless motors, remain active.
• The motor transducer can be both a resolver (2 to 24 poles) and an incremental
encoder (1024 to 8192 pulses).
• It is possible to program the device in 2 different languages: Italian and English. The
required language should be specified in the purchase order.
• The power supply voltage range can be from Three-phase 65 V
ac
to 510 V
ac
with no
previous setup.
• With power supply voltages lower than 120 V
ac
Three-phase, it is necessary to supply
a 24 V
dc
auxiliary voltage.
