The BLD 3502-SE2P is a 2-Quadrant PWM (Pulse-Width Modulation) Servo Amplifier suitable
for speed control of our three-phase brushless DC-Servomotors, type 1628, 2036 and 2444.
The phase commutation sequence of the brushless DC-Servomotor is automatically made by
the Servo Amplifier.
A specially designed frequency-to-voltage converter allows precise speed regulation
(regulator type P, proportional).
Two amplifier configurations for speed control:
•
Hall sensors signals for operation above 1000 rpm;
•
Encoder signals for operation down to 100 rpm.
The Servo Amplifier is supplied with Hall sensor configuration as standard.
The analog speed command is a unipolar signal, from 0 to +5 V, (optional 0 to +10 V)
producing a fixed speed proportional to the input voltage.
The maximum output power without additional heat sink is 50 W.
