How to Select a Drive

EDM 453
Stepper motor drive circuit for full, half and microstep mode
Bipolar chopper driver, 3A per phase, 45V
LVD
High-performance low-voltage servo drive, for small and large brushed or brushless DC motors
12-48 VDC, 7A RMS max continuous, 12A RMS peak, CANopen interface

Selection criteria

STEPPER DRIVE

Stepper motor winding

Unipolar/bipolar connection

Driver type

L/R are equivalent to voltage drive, Chopper drive or PWM are current source.

Current and voltage rating

It defines the amount of current the drive can deliver, and it also defines the power supply requirements.

Chopper frequency

The chopper frequency is the frequency the motor coils are powered.
The current value is regulated by the ratio time ON versus time OFF.

Additional options

Boost option, standby option, short circuit protection, overtemperature protection

DC/Brushless DC DRIVE

Current and voltage rating

It defines the amount of current the drive can deliver, and it also defines the power supply requirements.

Feedback

Typically, incremental encoder; TTL single-ended or RS-422 differential

Servo control

PWM frequency range.
Current, velocity and position modes of operation

Reference command

CANopen, serial command, analog input

Additional options

Boost option, standby option, short circuit protection, over-temperature protection, feedback loss
