DigiDrive Manual Series 2000 / 4000
CHAPTER A DESCRIPTION AND TECHNICAL DATA
The servo-amplifiers series 2000 and 4000 are intended for the control of 3 phases brushless
servo-motors equipped with resolver and asynchronous servo-motors equipped with resolveror
encoder.
To avoid any confusion, the motors regulated by the series 2000 and 4000 servo-amplifiers
should have the following characteristics:
Rotor constructed with permanent magnets or winding cage arranged in 1, 2, 3, 4, 5 or
6 pole pairs, without commutator.
Stator constructed with 3 windings connected in star or delta.
Brushless motors : electronic commutation is only effected by means of a speed one
resolver (motors with Hall effect sensors and tachogenerator are not suitable).
Asynchronous motors : electronic commutation is only effected by means of a speed
one resolver or an incremental encoder.
The servo-amplifier series 2000 and 4000 are fully digital. High-performance torque, speedand
positioning control fulfils all requirements for rapid response and control accuracy.
Digital control allows comprehensive diagnostics, motor parameters tuning, data andfault
logging, etc.. using a PC based user program.
A wide range of firmware assures that it will meet the requirements of practically anyapplication.
The particular features of the servo-amplifiers series 2000 and 4000 are described there under:
Power supply
Single-Axis unit incorporating a braking module for connection to 3 phase power. The
drive also can be run from a common DC-bus voltage.
