Table 4 – Modbus registers
10.5 Normal operation
Write the speed reference in SpeedSet between 0 and 1000 (0-100%). Note that the conversion from SpeedSet to
rpm speed is non-linear. The reference in rpm can be read using register SpeedSetScaled. The minimum and maximum
speed can be read in registers MinSpeed and MaxSpeed.
Start the motor by setting Operation to 1. Stop it by setting it to 0. You can change the speed while the motor is run-
ning.
If communication with the device is stopped, a warning will appear after 10 seconds but the motor will keep running.
Faults and warnings can be reset by setting operation Bit 3.
