• Write 4000 (0x0FA0) to the “Speed set-point” register, this will set the set-point speed to 4,000 rpm.
• Write 1 (0x0001) to the “Operation” register, this will set the motor drive to RUN-state and the tool will start running.
• Write 2 (0x0002) to the “Operation” register, this will set the motor drive to STOP-state and the tool will stop running.
• Write 8 (0x0008) to the “Operation” register, this will set the motor drive to OFF-state.
Digital interface
The motor drive can also be controlled via the digital interface instead of Modbus RTU, but with the added drawback
that there is no feedback when using the digital interface. To enable the digital interface, the JP12 jumper needs to be
set.
Connector J5 is used as input for the digital interface. The input is considered high if a voltage between 15–33 VDC is
applied to the input pin. The input is considered low if the voltage is below 12 VDC or if the input is left floating. The GND
pin of connector J6 must be connected between the systems. The J6 connector can also be used to provide a 15 VDC
control voltage if needed.
