COMPACT SERVO DRIVE, ACSD
Introduction
ACSD is a compact speed servo drive family for controlling
synchronous AC brushless servomotors.
It has two series depending on the supply voltage they can be
connected to: Hence, we will refer to:
where each of them will have the following models depending on
their peak current:
 For the “ACSD-xxH” series:
with peak currents of 4, 8 and 16 A.
 For the “ACSD-xxL” series:
with peak currents of 5, 10, 20 and 30 A.
General characteristics
Their main characteristics are:
 Three phase power supply.
 Dynamic braking in case of mains failure.
 PWM IGBTs.
 2500-line incremental TTL encoder feedback or 1Vpp sinusoidal
encoder.
 CAN field bus communication interface.
 Two logic inputs to control the motor (speed enable and drive
enable).
 One programmable logic input.
 One programmable logic output.
 “On-line” parameter editing.
 Typical protections in velocity drives.
 RS-232 communication (only for uploading software).
 CANopen communication protocol.
