MDD 121-1
Axis Module 400 V/480 V MDD 121-1

1 Overview

The MDD 121-1 is an axis module for two axes with a
continuous sum current of 6 A at 230 V and 4 A at 400/480 V
and a peak current of 18 A at 230 V and
12 A at 400/480 V.
MDD 100 is a small to midsize power range servo drive
system, especially developed for multi-axial applications in
the low, middle and high performance range.
It is fully integrated in the LASAL operating system and has 1
to 8 servo axes.
Depending on the supply module used and the motor type,
the system is a 1-phase 230 VAC or a 3-phase 400-480 VAC
system.
Four axis modules are available, two single-axis modules for
230 V and 400 V and two dual-axes module for 230 V and
400 V, which have a scalable output current range of the 2
axes.
The supply module and the axes modules are put on a
module carrier, which is mounted on the mounting plate of the cabinet.
The current, speed, and position control of the up to 8 axes work with a cycle time
of 62.5 µs. MDD 100 has a high flexibility in connection of various feedback systems.
VARAN connects the servo drive system to the machine controller.
Integrated safety functions "Safe Torque off" STO and "Safe Stop 1" SS1 with a high safety
level ease the integration into the safety concept of the machine.
