AC20 Series AC Variable Frequency Drives, kW Rated
The AC20 general purpose drive provides advanced Ethernet connectivity and Safe Torque Off for open or closed loop AC induction and PM motor control in applications up to 180kW
Description
The AC20 Advanced Compact Drive is a highly
featured yet economical solution to general purpose
motor control applications. AC20 provides speed
or torque control in the power range 1.5 kW to
180 kW. Its compact dimensions house many
features normally only associated with system
drives, including sensorless vector mode for control
of Permanent Magnet (PMAC) and AC induction
motors, encoder feedback and IO expansion option
cards, Safe Torque Off and an onboard Ethernet port
that supports major industrial Ethernet protocols.
AC20 provides the perfect solution for OEM machine
builders looking for a compact, cost-effective drive
without compromising on performance
AC20 is designed to reduce the time and effort
required to select, install, set up and commission
Two variants of option card are available, and both
are user installable/retrofittable. Minimal wiring
requirements with two easily accessed terminal rails
and removable power cable earthing brackets make
AC20 fast and simple to install. All AC20 come with
a high quantity of user configurable IO and a user
disconnectable C3 EMC filter as standard.
Programming and commissioning is made simple
through its easy to use integrated keypad and the
DSELite programming tool
Proven technology and manufacturing techniques
ensure AC20 has been engineered and built
to deliver consistently outstanding levels of
performance day in, day out - ensuring maximum
uptime and productivity.
Thanks to its conformally coated PCBs, AC20 is built
to withstand C3 environments.
AC20 has been designed with system compatibility
in mind. The compact footprint allows installation
into existing spaces, while the IO count has been
chosen to allow maximum possible flexibility. The
internal block diagram is fully featured to enable
replacement of legacy Parker inverters, and the
onboard Ethernet communications protocols aid
integration into wider systems. Retrofittable, plug-in
communications cards cover all popular protocols
and are simple to configure.
