ii. If positioning control is desired, contact your
or Local Business Partner to upgrade your
actuator to positioning control.
4. Diagnostics show a Motor Stall Fault.
a. The easyDrive electric actuator is designed to operate in a manner consistent with a pneumatic actuator. This
means that if the valve plug can not move to its commanded position, the actuator will stop, without damage,
and issue a Motor Stall Fault warning. When the command signal changes outside of the deadband (Modbus
register 40036), it will attempt to move again. Recalibrate the actuator span per instructions in the Startup
section of this manual.
5. Position on D3 is not accurate (proportional positioning units only).
a. If the position of a D3 is too high (i.e. 50% is much higher than 50% on the bonnet), check the valve type. If valve
type is D4, change to D3, cycle power, and recalibrate.
b. If the local analog input is being used (420mA or 15V), the analog inputs of the actuator may be calibrated to
match the input signal.
i. Command 0% (4mA or 1V).
ii. Using a Modbus link, send a 1 to register 40004 or use the Fisher easyDrive configuration software by clicking
the button “Analog Cal at 0%”.
iii. Command 100% (20mA or 5V).
iv. Using a Modbus link, send a 1 to register 40005 or use the Fisher easyDrive configuration software by clicking
the button “Analog Cal at 100%”.
