CAUTION! If the voltage amplifier emits smoke, high heat, or unusual smells, immediately turn off the power switch and unplug the power plug from the outlet. Then contact our technical service. www.newport.com... -
Page 11: Maintenance And Inspection
6.3 Maintenance and Inspection CAUTION! Before cleaning the exterior box of the voltage amplifier, turn off the power switch and unplug the power plug. Failure to do so may result in a fire or electrical shock. Clean the exterior box using a damp cloth that has been firmly wrung-out. Do not use alcohols, benzene, paint thinner or other inflammable substances. -

The slew rate of the amplifier can be adapted to your system using the "slew rate" limiter or the 4th order low pass filter, i.e.

Depending on your special application and load, the mechanical response can be optimized. www.newport.com...

Page 28: Scan Function
The scan starts with “ss,1”. During a scan, the status can be requested with "ss<CR>". The answer “ss,2” means the scan is still running, “ss,0” indicates the scan is complete. A running scan can be aborted by setting the status to zero (ss,0<CR>). www.newport.com... - Page 29 Example: scan sine , 100% amplitude, 0% offset, frequency = 0,2Hz gfsin,0.2<CR> gasin,100<CR> gosin,0<CR> scan type: sct,1 start scan: ss,1 sketch 5: output voltage of a sine scan (open loop) Application: The combined use of trigger generation and scan function permits a highly exact scan of a probe. Acceleration forces (and with it oscillations) are minimized by using a sine function, and actions can be initiated by the trigger generation at exactly defined actuator positions.

10 Controller Adjustment When any actuator made by Newport Corporation is connected to the NPCxxxDIG, amplifier their specific values are read from the actuator’s ID-chip. The Digital Signal Processor (DSP) of the amplifier is set with these values. These parameters were investigated in the Newport Corporation laboratory and ensure safe function of the actuator. -
