LA Series Linear Servo Amplifier Technical Reference Manual

Warning! Potentially lethal voltages exist within the amplifier when power is
applied. Never attempt to handle or probe the amplifier with power applied.
This product contains static sensitive devices and requires proper handling with
ESD protection.
These amplifiers are capable of producing large amounts of energy. Serious
injury or death can result from improper motor or load movement. The amplifier
requires an external controller for Sinusoidal mode operation to commutate the
motor properly. In Trapezoidal mode operation, the amplifier requires properly
phased Hall sensors for commutation. Verify proper Hall sensor phasing and
motor direction before connecting any load to a motor.
Do not connect the motor to the system load during initial testing and installation.
These amplifiers require customer supplied airflow for proper operation.
Operation of the amplifier without proper cooling will void the warranty. Contact
the factory for information on adequate airflow for your application.
Be sure power is off when inserting or removing connectors or connections.
For motors with a phase to phase inductance of less than 250uH, please consult
the factory. A special set of current loop bandwidth components will need to be
installed for safe operation of the amplifier.
CAUTION! READ THIS SECTION BEFORE PROCEEDING.
