NY4125: 5-axis low power PWM Drive Module
9.1
Overview
The NY4125 is a 5-axis PWM (Pulse Width Modulation) drive module, which
can drive brushed DC motors and brushless AC (BLAC) motors. The NY4125
is a cost-effective solution for low demanding applications. Part number is
R911172221, ordering code is NYM04.1-5PW-NNNN-NY4125.
One NY4125 5-axis low power PWM Drive module can be installed in the
NY4063 system housing. The NY4125 drive module must always be installed
in drive slot 0 of the NY4063 system housing, the drive slot right next to the
MCU. Note that only the NY4063 system housing supports the NY4125.
Support for quadrature encoders with and without index pulse, digital Rexroth
MSM encoders and EnDat2.2 encoders is available on-board. The
quadrature encoder is also known as A/B encoder, S0S90 encoder and 3-
channel digital incremental encoder. See
for the supported encoder types.
