Hi

I don't think developing a model 3 motor driver for this piezo controller makes sense. Model 3 motor driver requires other parameters such as velocity, motor resolution, homing, jogging, etc. A stream device interface works the best for your case.

Best Regards,
Abdalla.

Dear EPICS mates,

I need to control a piezo actuator via
Piezosystem Jena's piezo controller NV 40/1 CLE,
which is very old and discontinued.

Its commands are extremely simple:(please see attach files)
i1  activate remote control
i0  deactivate remote control
cl  closed loop on
ol  closed loop off
rd  read a value (µm for closed loop, volt for open loop)
wr,<value>  write a value  (µm for closed loop, volt for open loop)

I'm wondering if it's possible to develop
a "Model 3" motor driver for it.

Do you guys have experience for similiar suuch simple devices?
