ACD48 Motor Drive Series
The ACD Series motor controllers from Performance Controls, Inc. (PCI) are AC motor drives/invertors for use in battery-powered vehicle applications. They utilize a high performance Digital Signal Processor (DSP), high efficiency MOSFET’s and proprietary control techniques to provide smooth, reliable motor control and programming flexibility. Parameters are available to optimize motor performance, set acceleration/deceleration, set forward/reverse speed limits, and provide other functions. The ACD Series can be customized with expanded voltage or current ranges, alternative form factors, OEM labeling, and other features.
- For Brushless Permanent Magnet and AC Induction Motors
- 24 – 48 VDC Supply Voltage
- 4 Quadrant Operation
- Dual Traction Drive Capability
Applications
The ACD Series motor controllers can be used in these and other applications:
- Vehicle traction, steering, hydraulic pumps and other vehicle auxiliary systems
- Automated guided vehicles (AGV’s)
- Material handling vehicles
- Other battery-powered motion applications
Features and Benefits
Digital Tuning
Optimizes performance, enables cloning, eliminates pot drift, and reduces inventory through the use of the same drive for multiple applications.
Proprietary High Frequency PWM Technique
Enables quiet operation, provides responsive torque and velocity control, efficiently uses supply voltage, and decreases heating and losses in motor.
Health Monitor (Data Logger)
Logs faults, warnings, alarms, and peak values to non-volatile memory for system maintenance and repair.
Electrical Isolation
Eliminates the need for external isolation components and is good for ‘floating battery’ designs for single-point failure immunity.
High Voltage Components
Allow supply voltages as high as 75 VDC while charging without having to use relays or other methods to disconnect the drive from the battery.
"Get Me Home" Over-Temperature Warning Mode
Provides warning and linear reduction of current limit to allow continued operation at reduced capacity for a controlled shutdown.
Regenerative Braking
Recharges battery while operating
Master/ Slave Operation
Coordinates multiple axes (such as dual traction drives) from a single command and allows digital mode selection. Reduces drive inventory since drive works as either master or slave.
Internal Closed-Loop Speed and Torque Control
Eliminates need for an external controller, allows separate forward/reverse speed limits, and provides smooth transitions with programmable acceleration/deceleration.
Optional Separate Logic Suppy
Provides additional safety measure by optionally powering internal control logic from a separate power supply.
Superior Fault Protection
Safeguards both amplifier and motor against faults which may occur.
