NY4120 and NY4120/10: PWM Drive Module
8.1
Overview
The NY4120 is a PWM (Pulse Width Modulation) drive module, which can
drive two axes of the BLDC/BLAC (Brushless DC/AC) motors, DC motors or
stepper motors. The NY4120/10 is designed for linear motors in combination
with the NY4960 Linear Motion System (LMS) MUX module and the NY4073
or NY4078 system housing, or the NY4074 or NY4079 system housing. Part
number for the NY4120 is R911318961, ordering code is
NYM04.1-2PW-NNNN-NY4120. Part number for the NY4120/10 is
R911320447, ordering code is NYM04.1-2PW-LMSN-NY4120/10.
Support for quadrature encoders with and without index pulse is available on-
board, as well as other encoders, and there is a possibility to add one
NY4199 SinCos Option module to connect another position sensor (for
example EnDat or SinCos). The quadrature encoder is also known as A/B
encoder, S0S90 encoder and 3-channel digital incremental encoder. See
chapter 13 "Encoders" on page 157
for the supported encoder types.
