I agree.

But I would like to provide motor record for this piezo controller,

in order to treat it like a motor.

Can't I just provide dummy values for these parameters?

Subject: EPICS modulle for Piezosystem Jena's piezo controller NV 40/1 CLE

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?
