Page 4: Introduction
1 Introduction This manual describes the piezo amplifiers NPC & NPCSG from Newport Corporation. You will also find additional information regarding piezoelectric products. Definition: All systems from Newport Corporation such as electronics, actuators and optical systems are called units. If you have any problems please contact the manufacturer of the system: Newport Corporation, 1791 Irvine Ave. -
Page 5: Declaration Of Conformity
2016 Type of Equipment: Electrical equipment for measurement, control and laboratory use in industrial locations. Manufacturer: Newport Corporation 1791 Deere Avenue Irvine, CA 92606 U.S.A. We hereby certify that the above described device in its conception, construction and form put by us into circulation is in accordance with all relevant essential requirements of the EMC Directive 2014/30/EU. -
Page 6: Purchased Part Package
5 Instructions for using piezo electrical elements and power supplies Piezoelectric actuators from Newport Corporation are controlled by voltages up to 150V. These values can be quite hazardously. Therefore read the installation instructions carefully and only authorized personal should handle the power supply. -

For information about where the user can drop off the waste equipment for recycling, please contact your local Newport representative. Control of Hazardous Substances... -
Page 8: Installation, Power Supply
Please use only original parts from Newport Corporation. Newport Corporation does not give any warranty for damages or malfunction caused by additional parts not supplied by Newport Corporation. Additional cables or connectors will change the calibration and other specified data. This can change the specified properties of the units and cause them to malfunction. -
Page 9: Operation
Always grasp the plug portion when unplugging the power plug. Pulling on the power cord may expose or snap the core wire, or otherwise damage the power cord. If the cord is damaged, this could cause an electricity leak and result in a fire or electrical shock. CAUTION! ... -

Each piezo can be controlled separately by turning the voltage offset, by applying an analog voltage signal of 0 to 10V or by PC interface. The voltage of the monitor output correspondents to either applied piezo voltage (NPC3, NPC120) or completed motion (NPC3SG, NPC120SG). -
Page 14: Amplifier Without Integrated Feedback Controller
Any system delivered as open loop mode cannot be modified to closed loop later on. Any closed loop system can be easily calibrated to a different closed loop piezo afterwards. This is only possible at Newport Corporation and will cause additional effort and costs. Please contact our sales team for more information. -

Based on this a signal of 0V is related to an applied voltage of –20V and +10V is related to +130V. In closed loop the minimum and maximum values never reaches caused by the closed loop control reserve. monwpa,x,1: Output of a voltage proportional to the actuator position (delivery status).

call: fenable,<ch>,<0|1> example: fenable,0,1 answer: none the soft start function is switched on for the channel 0 (PIEZO 1) This command 'fenable' enables the soft start function for the given channel. After switching on the system the soft start function is started for 10 seconds to initiate the actuator. While this routine the actuator is moved once through the whole motion range and back. -
