Connecting using the Fisher easyDrive configuration software
The Fisher easyDrive configuration software allows configuration and diagnosing of the Fisher easyDrive electric
actuator with a graphical interface. Connect a PC to the actuator using a USB or serial to Modbus RTU converter using
the wiring instructions above. The USB or serial device will be visible in the drop menu under Serial Port Settings. Baud
rate and parity should be set to the Modbus settings of the actuator. Default actuator settings are 9600 baud and Even
parity.
Use the Fisher easyDrive configuration software (figure 8) to make the desired changes, or register values may be
changed to allow different functionality. Modbus register 40034 dictates whether the unit will respond to a physical
signal or to the value in Modbus register 40001. A value of 0 in register 40034 will result in the actuator responding to
the value in 40001 and a value of 1 will result in the actuator responding to physical control signals.
Note
If an actuator is on/off, a Modbus command of 049 in register 40001 will cause the valve to close fully, while a value of 50100 will
cause the valve to open fully.
