1.2 Operation mode and feedback
Description
This is a drive capable to drive DC brush motors, up to 3Nm. It‘s a High Performance full four
quadrant drive servo amplifier. The mosfet output power stage is controlled by a 20 Khz PWM
(Pulse Width Modulation) signal that allows it to drive servo motors where high dynamic per-
formance and precise speed is required.
Operation mode
General characteristic
Velocity feedback
Closing the velocity feedback loop to motor may be done in several different ways to accom-
modate most applications. This types of velocity feedback are available with DC brush motors.
Velocity feedback
• DC motor with encoder
• DC motor with internal PWM (Armature)
• DC motor with tachogenerator
It is speed piloting using an analogue
reference (differential or common mode)
It is torque piloting using an analogue
reference. This function allows you to control
the current from the drive. SPEED CONTROL
