Register 10 - Motor 1 – Default % Out
When the EVO/ECM-Modbus RTU is reset, the value stored in register 10 is transferred to register
2. Register 2 sets the airflow (torque) for motor 1. The motor operates at this airflow until the
Modbus RTU Master changes the value in register 2. Defaults may also be selectively invoked
during loss of communications with the Modbus RTU Master.

Low Byte
Motor Enable/Disable Defaults Nibble
This nibble sets the default enable/disable state for each ECM Motor. When the EVO/ECM-
Modbus RTU resets, the value stored in this nibble is transferred to the enable/disable nibble in
register 1. This causes each motor to be enabled or disabled to the associated default value. The
Modbus RTU Master changes the value in register 1 enable/disable nibble when communication is
established. Defaults may also be selectively invoked during a loss of communications with the
Modbus Master.
Bit 0 = Motor 1, Bit 1 = Motor 2, Bit 2 = Motor 3, and Bit 3 = Motor 4.
