Fall River,
– maxon’s EPOS 24/1 is a digital motion controller capable of position, velocity,
and current mode. Available in two
versions for brushed or brushless motors, the small package size and
cost-efficient design makes the EPOS 24/1 an ideal choice for controlling small
motors. Dimensions are 55 X 40 X 25 mm
(2.2 X 1.6 X 1 in) and weight is 45 g (1.6 oz). Communication is via RS-232 or
CANopen. Software for CANopen and
Windows DLL’s is complimentary.
Requiring a supply voltage of
9-24
the controller is capable of 1 A max continuous current and 2 A peak
current. Efficiency is up to 85%. The 50 kHz switching frequency and built-in
choke insures compatibility with most low inductance motors, while the
sinusoidal commutation for brushless motors insures minimal torque ripple and
low noise. Maximum motor speed is 25,000
rpm for 2-pole motors. A maximum encoder
input frequency of 1 MHz, six digital inputs, two digital outputs, and two
analog inputs allows for maximum flexibility.
The wide input voltage range of 10 to 50 V means that the DECS 50/5 is very flexible and adaptable. In continuous operation, an output current of 5A of the power stage is permissible, giving it a maximum output performance of 250 Watts — all this with it only being the size of a business card. The speed value can be set via an integrated potentiometer or an analog set value. The 1-Q amplifier can be operated at up to a maximum speed of 80 000 rpm.
The DECS 50/5 also provides control inputs for selecting motor direction, enable and braking. An operating status display (LED) and speed monitor output complete the convenient control features. Plug-in screw terminals and a Flexprint connector for maxon flat motors are available for the connection.
