Default Reset
To reset non-volatile registers to factory default values, write 65535 (FFFF hex) to Register 14, and then cycle power.
Register 12 Current Motor Speed Instruction (0-100% Duty Cycle)
Used for closed loop applications in which Register 2 is the desired set speed and register 12 is the actual motor speed
duty cycle as the closed loop control function regulates applied motor power to maintain your desired set point.
Register 27 Number of Pulses per Revolution
Used to determine how many pulses coming back from the motor equal 1 revolution. Please refer to the motor
manufacturer’s specification for what this value should be. With EBM EC motors this value can be either 1, 2, or 3.
MODE SELECTION AND WATCHDOG ENABLE - REGISTER 23
Communication Watchdog
ACM1015’s communication watchdog feature acts as a safe guard against system crashes.
If a Modbus
®
packet with a valid CRC is not received at least every 30 seconds, the watchdog activates and causes a
complete micro-controller reset. Should a watchdog event occur, a non- volatile counter is incremented. This counter can
be read in Register 26. Writing to Register 26 clears the counter. This feature can be enabled by writing a value to Register
23 with the Bit 4 set.
