Unidrive Classic is the drive that established Control Techniques’ universal platform. Two supply classes were built: the 200 V to 240 V range covers 0.37 kW to 22 kW in sizes 1 to 3, and the 380 V to 480 V range covers 0.75 kW to 160 kW in sizes 1 to 5, with output current from 2.1 A to 300 A per unit.
A single unit runs any of the control modes: open loop V/Hz or sensorless vector, closed loop flux vector, and servo for brushless motors. Options plug in as UD modules for MODBUS, PROFIBUS-DP, INTERBUS S and DeviceNet, with UniSoft for commissioning.
In the model number, UNI is the prefix and the character after it gives the frame size, 1 to 5. Each size 5 unit is rated at 300 A and up to eight can be paralleled for 2400 A, so the only size 5 model number published is UNI5401 and any larger output is several of those together.
Universal platform: V/Hz, sensorless vector, closed loop flux vector and servo control in one drive
Frame sizes 1 to 5, 0.37 kW to 160 kW, across 200 V and 400 V supply classes
Maximum output frequency 2000 Hz in open loop, and 30,000 rpm maximum speed in closed loop
More than 700 parameters with nine pre-configured application macros
Internal braking transistor fitted as standard
UD option modules for MODBUS, PROFIBUS-DP, INTERBUS S and DeviceNet

Model numbers are shown without the UNI prefix, and the 200 V and 400 V rating tables are combined so the voltage group column shows which table each row came from. UNI5401 is the only size 5 model number in the manufacturer's own literature; larger outputs are built by connecting size 5 units in parallel.
