GD1 – Installation Guide
1.1 – INTRODUCTION
GD1 all-digital drives with sinusoidal PWM control are servo drives that provide the control of brushless AC
motors with a sensor (resolver, encoder or, as an option, second encoder sensor on the load).
Several versions are available:
♦
with integrated power supply unit: 230 V
♦
with external 230 to 480 V
The very small dimensions allow an easy mounting in low depth cabinets.
Height (235 mm) and depth (224 mm) are the same for all voltage and current ratings.
The drives with current rating ≤ 45 A have a single width with 74.5 mm pitch whereas drives with 60 A and 90 A
ratings have a double width with 145 mm pitch.
The drives with current ratings smaller than 8 A in 230 V have reduced 175 mm depth. The angle brackets can be
reverse side mounted in order to allow a wall-crossing fastening. This solution offers the advantage to separate
the part of the drive which requires heat dissipation.
