MICROSPEED
REV 04/05
The Microspeed Servo Amplifier is a compact full DC
four quadrant drive. The (MOSFET) output power stage
is controlled by a 22 Khz PWM (Pulse With Modulation)
signal that allows it drive small to medium sized brushed
servo motors (up to 2Nm) where high dynamic perfor-
mance and precise speed is required.
The Microspeed only requires a single power supply
to operate and develops all needed voltages on board
to make power supply design easy and convenient.The
imput voltage is from 12 to 130 Vdc max "See Tecnical
Data". (Chapter 4 describes how to design a proper
supply.)Closing the velocity feedback loop to motor
may be done in several different ways to accommodate
most applications. Three types of velocity feedback
are available with these drives.
Feedback Types: Tachogenerator, Armature,
Encoder(option), PWM+Dir (option)
Two inputs are present for the disabling of clockwise
and counter-clockwise motor rotation (+LM SW,-LM
SW.option)
The possibility to completely adjust the Dynamic
Constant exists by inserting new values "as opposed to
the standard mounted values".
The insertion of various prearranged operational drive
values are easily realized by opening and closing solder
points. The intervention of drive protections are all
visible with LEDs on the front of the drive.
The nominal current, as well as peak current is adjusted
through resistance on the base.
The operating temperature is from 0 to +40 °C (32° to
104°F). In accordance with the current size and model,
supplemental ventilation can be requested.
