SD
Enhanced drives
Main features:
• Multiform Control Modes
• On Board Safety provisions:
√ fully tested for direct installation unit
√ built in watch dog functionality
√ fault monitoring and handling
√ on field working errors buffering
Description:
The SD fieldbus drives are Full Digital high performance
micro-step devices, able to control stepper motors through
Canopen, Profibus-DP or Modbus-RTU commands, also in
closed loop of torque, speed and position in slave
mode.
With their embedded Advanced Power Motion Module
and the inputs and outputs they are suitable for local devices
to be easily connected to fieldbus systems for the
driving of 2 or 4 phase hybrid stepper motors.
• Main advantages of the drives:
√ low motor vibration
√ low mechanical noise
√ low heat generation
√ closed loop of torque,
velocity and position
√ energy saving
√ no resonance
√ high reliability
√ DC/AC power supply
√ wide range of power
A wide drives series of different power levels are available
to combine with motor series with a
flange size from 1.7” to 4.2”. These
drives can be applied to many machine
types such as labelling systems,
laser cutters, pick-and-place devices,
incision tables, etc. and are suitable
for applications requiring a high precision,
speed and easiness of use.
The units can be configured with ad
hoc firmware to immediately realize
complete applications, such as labelling
systems with advanced functions,
thread guiding and advanced indexing
on specific placements.
