About
The NPAPC is a line of the most advanced PWM servo drives available today.
It is specifically designed to address the most demanding applications with regards to move and settle times,
standstill jitter, and velocity smoothness, such as wafer metrology and inspection, FPD inspection, and ultra-precision
machining for processing of optical components.
The NPAPC is based on ACS' proprietary and unique proprietary and unique technology that exceeds the stand still jitter and
tracking error performance that until now has been achieved only with linear drives while gaining all the benefits
of a PWM type drive, such as lower heat dissipation, smaller size, and better reliability.
The NPAPC is designed to operate by any motion controller that supports two ±10V sine wave current
commutation commands.
The Unique feature enables the motion controller to dynamically modify the current/command gain of the drive for
higher resolution low level current control and thus providing better velocity smoothness and lower position jitter control.
The current loop PI filter is programmable. Its gains can be selected by setting four logic inputs to one of 16 pre-set values
as well as programmed using the SPiiPlusMMI software suite.
The drives are protected against over current, over temperature, and over voltage. The unit supports motor over
temperature protection.
The unit can control external relays to shorten the phases of the motor for dynamic brake proposes.
