1,2 drives, 12-100V, up to 13.3/40A
Single/Dual Axis NanoPWM Drive with ±10V commands interface
The NPAPM 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 NPAPM is based on ACS' proprietary and unique technology that exceeds 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 unit is designed to operate with 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 and its gains can be set either by a DIP-Switch setting to one of 16 pre-set values. Finer tuning can be done by using PC based setup software.
The drives are protected against over current, over temperature, and over voltage. The unit supports motor over temperature protection.
Optional built-in relays will shorten the motor phases when the drive is disabled.
Optional STO (Safe Torque Off) is available to comply with EN ISO 13849-1 system safety standard.
