2 HDC2450 Motor Controller Datasheet Version 1.2. July 20, 2010
• Precise speed and position control when Encoder feed-
back is used
• PID control loop with separate gains for each channel
• Multi-range PID gains changing on-the-fly according to
motor speed
• Optional Mixed control (sum and difference) for tank-like
steering
• Configurable Data Logging of operating parameters on
RS232 Output for telemetry or analysis
• Built-in Battery Voltage and Temperature sensors
• Optional 12V backup power input for powering safely the
controller if the main motor batteries are discharged
• Power Control wire for turning On or Off the controller
from external microcomputer or switch
• No consumption by output stage when motors stopped
• Regulated 5V output for powering Encoders, RC radio,
RF Modem or microcomputer
• Separate Programmable acceleration and deceleration
for each motor
• Separate Programmable maximum forward and reverse
power
• Ultra-efficient 1.5 mOhm ON resistance MOSFETs
• Orderable as single channel version up to 300A
• Stall detection and selectable triggered action if Amps is
outside user-selected range
• Short circuit protection with selectable sensitivity levels
• 10 to 32kHz user programmable Pulse Width Modulation
(PWM) output.
• Overvoltage and Undervoltage protection
• Programmable Watchdog for automatic motor shutdown
in case of command loss
• Overtemperature protection
• Diagnostic LED
• Extruded aluminum, heat sinking enclosure for opera-
tion harsh shock and temperature environment
